Channel Allocation Plans

ROADM cards are designed for use with specific channels in the C band and L band. In most cases, the channels for these cards are either numbered (for example, 1 to 32 or 1 to 40) or delimited (odd or even). Client interfaces must comply with these channel assignments to be compatible with the NCS system.

The following cards operate in the C-band:

40-MUX-C
40-WXC-C
80-WXC-C
40-SMR1-C
40-SMR2-C
MMU

Table 1 lists the L-band channel IDs and wavelengths at ITU-T 50-GHz intervals. This is a comprehensive L-band channel table that encompasses present and future card capabilities.

Safety Labels

For information about safety labels, see the section, Class 1M Laser Product Cards.

40-DMX-C and 40-DMX-CE Card

The single-slot 40-channel demultiplexer C-band (40-DMX-C) or single-slot 40-channel demultiplexer C-band, even channels (40-DMX-CE) card demultiplexes 40 100-GHz-spaced channels identified in the channel plan (Table 2), and sends them to dedicated output ports. The overall optical power can be adjusted using a single VOA that is common to all channels. The 40-DMX-C card is unidirectional, optically passive, and can be installed in Slots 1 to 6 and 12 to 17.

The 40-DMX-C or 40-DMX-CE has two types of ports:

COM RX port: COM RX is the line input port for the aggregate optical signal being demultiplexed. This port is supported by a VOA for optical power regulation and a photodiode for per channel optical power monitoring.

Note

By default, the VOA is set to its maximum attenuation for safety purposes (for example, electrical power failure). A manual VOA setting is also available.

DROP TX ports (1 to 40): On its output, the 40-DMX-C or 40-DMX-CE card provides 40 drop ports that are typically used for dropping channels within the ROADM node. These ports are connected using five physical connectors on the front panel that accept MPO client input cables. (MPO cables break out into eight separate cables.) The 40-DMX-C card also has one LC-PC-II optical connector for the main input.

The following figure shows the 40-DMX-C or 40-DMX-CE optical module functional block diagram.

40-DMX-C and 40-DMX-CE ROADM Functionality

The 40-DMX-C (or 40-DMX-CE) card works in combination with the 40-WSS-C (or 40-WSS-CE) card to implement ROADM functionality. As a ROADM node, the node can be configured at the optical channel level using CTC, Cisco Transport Planner, and CTM. ROADM functionality using the 40-DMX-C (or 40-DMX-CE) card requires two single-slot 40-DMX-C (or 40-DMX-CE) cards and two 40-WSS-C (or 40-WSS-CE) double-slot cards (for a total of six slots in the chassis).

For other cards’ ROADM functionality, see that card’s description in this chapter. For a diagram of a typical ROADM configuration, see the section, ROADM Node in the Cisco NCS 2000 Series Network Configuration Guide.

40-DMX-C and 40-DMX-CE Power Monitoring

Physical photodiodes P1 through P40 monitor the power at the outputs of the 40-DMX-C or 40-DMX-CE card. P41 monitors the total multiplexed power at the input, calibrated to the COM-RX port. The following table shows the returned power level values calibrated to each port.

Related Procedures for 40-DMX-C and 40-DMX-CE Cards

The following section lists procedures and tasks related to the configuration of the 40-DMX-C or 40-DMX-CE card:

40-MUX-C Card

The single-slot 40-Channel Multiplexer C-band (40-MUX-C) card multiplexes forty ITU-T 100-GHz-spaced channels identified in the channel plan in Table 1. The 40-MUX-C card can be installed in Slots 1 to 6 and 12 to 17. The 40-MUX-C card is typically used in hub nodes.

The 40-MUX-C card has two types of ports:

COM TX port: COM TX is the line output port for the aggregate optical signal being multiplexed. This port is supported by both a VOA for optical power regulation and a photodiode for per channel optical power monitoring.

Note

By default, the VOA is set to its maximum attenuation for safety purposes (for example, electrical power failure). A manual VOA setting is also available.

DROP RX ports (1 to 40): The 40-MUX-C card provides 40 input optical channels. These ports are connected using five physical receive connectors on the card’s front panel that accept MPO cables for the client input interfaces. MPO cables break out into eight separate cables. The 40-DMX-C card also has one LC-PC-II optical connector for the main output. For the wavelength range, see Table 1.

The following figure shows the 40-MUX-C optical module functional block diagram.

Figure 2. 40-MUX-C Optical Module Functional Block Diagram

40-MUX-C Card Power Monitoring

Physical photodiodes P1 through P40 monitor the power of the individual input ports to the 40-MUX-C card. P41 monitors the total multiplexed output power, calibrated to the COM-TX port. The following table shows the returned power level values calibrated to each port.

40-MUX-C Card Channel Plan

Table 1 shows the 40 ITU-T 100-GHz-spaced, C-band channels (wavelengths) that are multiplexed by the 40-MUX-C card.

Related Procedures for 40-MUX-C Card

The following section lists procedures and tasks related to the configuration of the 40-MUX-C card:

40-WSS-C and 40-WSS-CE Card

The double-slot 40-channel wavelength selective switch C-band (40-WSS-C) or the double-slot 40-channel wavelength selective switch even-channel C-band (40-WSS-CE) card switches 40 ITU-T 100-GHz-spaced channels identified in the channel plan (Table 1 or Table 2) and sends them to dedicated output ports. The 40-WSS-C or 40-WSS-CE card is bidirectional and optically passive. The card can be installed in Slots 1 to 6 and 12 to 17

The 40-WSS-C or 40-WSS-CE features include:

Receipt of an aggregate DWDM signal into 40 output optical channels from the Line receive port (EXP RX) in one direction and from the COM-RX port in the other direction.
Per-channel optical power monitoring using photodiodes.
Signal splitting in a 70%-to-30% ratio, sent to the 40-DMX-C (or 40-DMX-CE) for dropping signals, then to the other 40-WSS-C (or 40-WSS-CE) card.
Aggregate DWDM signal monitoring and control through a variable optical attenuator (VOA). In the case of electrical power failure, the VOA is set to its maximum attenuation for safety purposes. A manual VOA setting is also available.

Within the 40-WSS-C or 40-WSS-CE card, the first AWG opens the spectrum and each wavelength is directed to one of the ports of a 1x2 optical switch. The same wavelength can be passed through or stopped. If the pass-through wavelength is stopped, a new channel can be added at the ADD port. The card’s second AWG multiplexes all of the wavelengths, and the aggregate signal is output through the COM-TX port.

The 40-WSS-C or 40-WSS-CE has eight types of ports:

ADD RX ports (1 to 40): These ports are used for adding channels. Each add channel is associated with an individual switch element that selects whether an individual channel is added. Each add port has optical power regulation provided by a VOA. The five connectors on the card faceplate accept MPO cables for the client input interfaces. MPO cables break out into eight separate cables. The 40-WSS-C or 40-WSS-CE card also has one LC-PC-II optical connector for the main input.
COM RX: The COM RX port receives the optical signal from a preamplifier (such as the OPT-PRE) and sends it to the optical splitter.
COM TX: The COM TX port sends an aggregate optical signal to a booster amplifier card (for example, the OPT-BST card) for transmission outside of the NE.
EXP RX port: The EXP RX port receives an optical signal from another 40-WSS-C or 40-WSS-CE card in the same NE.
EXP TX: The EXP TX port sends an optical signal to the other 40-WSS-C or 40-WSS-CE card within the NE.
DROP TX port: The DROP TX port sends the split off optical signal that contains drop channels to the 40-DMX-C( or 40-DMX-CE) card, where the channels are further processed and dropped.

The following figure shows a functional block diagram of the 40-WSS-C or 40-WSS-CE card.

As a ROADM node, the node can be configured at the optical channel level using CTC, Cisco Transport Planner, and CTM. ROADM functionality using the 40-WSS-C (or 40-WSS-CE) card requires two 40-WSS-C (or 40-WSS-CE) double-slot cards and two 40-DMX-C (or 40-DMX-CE) single-slot cards (for a total of six slots in the chassis).

For information about ROADM functionality for other cards, see that card’s description in this chapter. For a diagram of a typical ROADM configuration, see the section, ROADM Node in the Cisco NCS 2000 Series Network Configuration Guide .

The following section lists procedures and tasks related to the configuration of the 40-WSS-C or 40-WSS-CE card:

40-WXC-C Card

The double-slot 40-channel wavelength cross-connect C-band (40-WXC-C) card selectively sends any wavelength combination coming from nine input ports to a common output port. The device can manage up to 41 channels spaced at 100GHz on each port according to the channel grid in Table 1. Each channel can be selected from any input. The card is optically passive and provides bidirectional capability. It can be installed in Slots 1 to 6 and 12 to 17.

.The 40-WXC-C card provides the following features:

Demultiplexing, selection, and multiplexing of DWDM aggregate signal from input ports to common output port.
Aggregate DWDM signal monitoring and control through a VOA.
VOAs are deployed in every channel path in order to regulate the channel’s optical power. In the case of an electrical power failure, VOAs are set to their maximum attenuation value, or to a fixed and configurable one. The VOA can also be set manually.
Per-channel optical power monitoring using photodiodes.

The 40-WXC-C card acts as a selector element with the following characteristics:

It is able to select a wavelength from one input port and pass the wavelength through to the common out port. Simultaneously, the card can block the same wavelength coming from the other eight input ports.
It is able to stop wavelengths from all nine inputs.
It is able to monitor optical power and control path attenuation using per channel VOA independently of the wavelength input-to-out port connection.

The 40-WXC-C card has six types of ports:

COM RX: The COM RX port receives the optical signal from a preamplifier (such as the OPT-PRE) and sends it to the optical splitter.
COM TX: The COM TX port sends an aggregate optical signal to a booster amplifier card (for example, the OPT-BST card) for transmission outside of the NE.
EXP TX: The EXP TX port sends an optical signal to the other 40-WXC-C card within the NE.
MON TX: The optical service channel (OSC) monitor.
ADD/DROP RX: The 40-WXC-C card provides 40 input optical channels. For the wavelength range, see Table 1.
ADD/DROP TX: The DROP TX port sends the split off optical signal that contains drop channels to the 40-WXC-C card, where the channels are further processed and dropped.

The following figure shows the 40-WXC-C optical module functional block diagram.

The usage of WXC and mesh PP power readings to troubleshoot a LOS-P in WXC COM TX port in Side A is described in the following example. The example is explained assuming a single wavelength 1558.17 in the setup that comes from Side H to Side A. If there is more than one wavelength, then there is a risk of dropping traffic when pulling common fibers. The example is explained below:

When the wavelength from side H is 1558.17, you can check the power reading at WXC EXP TX port of the WXC card and verify the consistency with side H pre output power and WXC COMRX-EXPTX port loss. You can also check with a power meter connected to the 8th fiber (since it is from side H) of an MPO-FC (or LC) cable connected to the TAP-TX port of the MESH-PP. This value should be consistent with the previous reading, less than the insertion loss of the installed PP-MESH. If it is consistent, the issue is with the MPO between side A WXC and PP-MESH. If it is not consistent, the issue is with the PP-MESH or the LC-LC from side H. With only the PP-MESH already tested during installation, the only issue can be with the patch cord b.

You can check if the 1558.17 wavelength from side H is unequalized (that is, if the channel is not aligned with the linear fit of the power values of the other channels) by keeping the DMX COM-RX port of side H in maintenance, and checking both the signal and ASE levels of CHAN-TX ports of the DMX card. If the channel is equalized (that is, if the channel is aligned with the linear fit of the power values of the other channels), then the issue is in the WXC side A that cannot properly regulate the VOA for such channel. If the channel is unequalized, then the issue is on a remote node.

Note

With an OSA or a spare 40 DMX, you can see the light coming from all the sides from TAP-TX of the PP-MESH.

Related Procedures for 40-WXC-C Card

The following section lists procedures and tasks related to the configuration of the 40-WXC-C card:

80-WXC-C Card

The double-slot 80-channel Wavelength Cross-Connect C-band (80-WXC-C) card manages up to 80 ITU-T 50 GHz-spaced channels identified in the channel plan and sends them to dedicated output ports. Each channel can be selected from any input port to any output port. The card is optically passive, and provides bidirectional capability. It can be installed in Slots 2 to 6 in the Cisco NCS 2006 and Slots 2 to 17 in the NCS 2015 chassis.

The 80-WXC-C card provides the following functionalities:

When used in the multiplexer or bidirectional mode, the 80-WXC-C card allows selection of a single wavelength or any combination of wavelengths from any of the nine input ports to the common output port.
When used in the bidirectional mode, the output wavelength from the COM-RX port is split to manage the express and drop wavelengths.
When used in the demultiplexer mode, the 80-WXC-C card, allows selection of a single wavelength or a combination of wavelengths from the common input port to any of the nine output ports.
Automatic VOA shutdown (AVS) blocking state on each wavelength and port.
Per-channel (closed loop) power regulation on the output port based on OCM block feedback.
Per-channel (open loop) attenuation regulation on the output port which is not based on the OCM feedback.

The OCM unit provides per-channel optical power monitoring on the following ports:

COM port in output direction
COM port in input direction
DROP-TX port in output direction
Eight Express/Add/Drop (EAD) ports and one Add/Drop (AD) port in both input and output directions

The 80-WXC-C card has 14 types of ports:

MON: The MON port monitors power on the COM T/R port.
COM RX: The COM RX port receives the optical signal from a preamplifier (such as the OPT-PRE) and sends it to the optical splitter.
DROP TX: In the bidirectional mode, the DROP TX port sends the optical signal to the demultiplexer.
EXP TX: The EXP TX port sends the split off optical signal that contains pass-through channels to the other side of the NE.
COM T/R: The COM port is bidirectional. It functions as a COM TX port in the multiplexer mode and as a COM RX port in the demultiplexer mode.
AD T/R: The AD port functions as ADD RX port in bidirectional and multiplexer modes and as a DROP port in the demultiplexer mode.
EAD T/R i (where i = 1 to 8): The EAD ports function as EXP ports in the bidirectional mode, as ADD ports in the multiplexer mode, and as DROP ports in the demultiplexer mode.

The different units of the 80-WXC-C card are:

40/60 splitter with VOA on drop path—The preamplifier output signal from the preamplifier is split in a 40%-to-60% ratio; 40% is sent on the drop path (DROP-TX port) and 60% is sent on the pass-through path (EXP-TX port). The VOA equipped on the drop path is used to match the power range of the receiver photodiode without the need for bulk attenuation. If a channel is expected to be dropped in the 80-WXC-C card, the pass-through channel is stopped after the EXP-TX port either by a 40-WSS-C or a 40-WXC-C card.
50 Ghz 10 port WXC—The WXC block is optically passive and has bidirectional capability. The WXC block can selectively send any wavelength combination coming from the eight input EAD ports and one AD port to a common (COM) output port, when used as a multiplexer, whereas it can selectively send any wavelength combination coming from its common (COM) input port to any of the eight output EAD ports and one AD port, when used as a demultiplexer. The WXC block can manage (on each port) up to 80 channels according to the channel grid reported in Table 1. Each channel can be selected from any input and routed to any output.
50 Ghz Optical Channel Monitor (OCM)—The OCM provides per channel power monitoring on the COM T/R, DROP-TX, AD, and EADi (i=1 to 8) ports. The power value for each wavelength is refreshed after a variable timer depending on the port and card activity.

The following section lists procedures and tasks related to the configuration of the 80-WXC-C card:

16-WXC-FS Card

The 16-WXC-FS card is a double-slot cross connect card, tunable over 96 channels in the C-band, at 50-GHz spacing on the ITU-T grid. The card provides the flex spectrum capability, which allows the user the flexibility to allocate the channel bandwidth, to increase the network scalability. The channel bandwidth is not fixed, but can be defined arbitrarily, with a given granularity and within a given range. Attenuation and power values are defined for each sub-range. The central frequency ranges from 191'350 Ghz (1566 .72 nm) to 196'100 Ghz (1528 .77 nm).

The 16-WXC-FS card can be used in point-to-point, ring, multi-ring, or mesh topologies. The 16-WXC-FS card supports up to 16 directions for each ROADM node. The card is optically passive and provides bidirectional capability. It can be installed in slots 2, 4, or 6 in the Cisco NCS 2006 chassis. It is recommended that you use the 16-WXC-FS card in slot 4 when used with EDRA amplifiers to comply with optical safety. It is recommended that you use the 16-WXC-FS card and the EDRA-2-xx card in slots 2 and 4, 5 and 7, 8 and 10, 11 and 13 of the Cisco NCS 2015 chassis.

Important

In the Cisco NCS 2006 chassis, the 16-WXC-FS card front panel has two compression latch devices. These latches enforce the position of the unit in the chassis. To insert or remove a card from the Cisco NCS 2006 chassis, rotate the compression latches fully in the anti-clockwise direction. After the card is inserted or removed, close the unit and rotate the compression latches fully in the clockwise direction.

For more information about the 16-WXC-FS card, see Cisco NCS 2000 16-port Flex Spectrum ROADM Line Card Data Sheet

16-WXC-FS Ports

The 16-WXC-FS card has these ports:

EXP-TXi (where i = 1 to 16)—The EXP TX port sends the split-off optical signal that contains pass-through channels to the other side of the NE. For example, in four degrees setup, the EXP ports can be used as drop Tx ports, EXP-Tx(1 to 4) are used as express channel from one side to other side. The 5th to 16th EXP-Tx ports are used to transmit the power to passive units.
EXP-RXi (where i = 1 to 16)—The EXP RX port receives the optical signal from the pass-through channels. For example, in four degrees setup, the EXP ports can be used as drop Rx ports, EXP-Rx(1 to 4) are used to receive power from the express channel from one side to other. The 5th to 16th EXP-Rx ports are used to receive the power from the passive units.
COM-TX—The COM TX port transmits the combined power from all directions or add drop ports towards the amplifier card.
COM-RX—The COM RX port receives the optical signal from a preamplifier card and sends it to the optical cross connect.
UPG-TX—The UPG TX port can be used to drop channels and transmits power to the preamplifier card. This port can also be used to increase the number of ports by connecting to another 16-WXC-FS card.
UPG-RX-The UPG RX port can be used to add channels and receives power from the preamamplifer card. This port can also be used to increase the number of ports by connecting to another 16-WXC-FS card.

Two LC-duplex adapters are required to connect COM and UPG ports, and four MPO connectors to connect add/drop ports of the 16-WXC card. All the 16 I/O ports of the 16-WXC-FS card can be used either for node interconnection or for add/drop.

Related Procedures for 40-SMR1-C and 40-SMR2-C Card

The following section lists procedures and tasks related to the configuration of the 40-SMR-1C and 40-SMR-2C cards:

17 SMR9 FS, 24 SMR9 FS, 34 SMR9 FS, and SMR20 FS/SMR20 FS CV Cards

The 17 SMR9 FS, 24 SMR9 FS, 34 SMR9 FS, and SMR20 FS/SMR20 FS CV cards are tunable over 96 channels in the C-band, at 50-GHz spacing on the ITU-T grid. The cards provide the flex spectrum capability, which give the flexibility to allocate channel bandwidth, to increase the network scalability. The channel bandwidth is not fixed, but can be defined arbitrarily, with a specified granularity and within a given range. For each sub-range, attenuation and power values are defined. The central frequency ranges from 191350 Ghz (1566 .72 nm) to 196100 Ghz (1528 .77 nm).

The 17 SMR9 FS, 24 SMR9 FS, 34 SMR9 FS, and SMR20 FS/SMR20 FS CV cards are single-slot cards that integrate two cross-connect blocks (multiplexer and demultiplexer), a variable gain EDFA pre-amplifier, and a variable gain EDFA booster amplifier. In addition, the SMR20 FS CV card has a dedicated laser source at the demultiplexer section, and a photodiode at the multiplexer section; these support the connection verification capability. The 17 SMR9 FS, 24 SMR9 FS, and 34 SMR9 FS cards support up to 9 directions for each ROADM node. The SMR20 FS/SMR20 FS CV card support up to 20 directions for each ROADM node. The cards can be installed in any service slot in the Cisco NCS 2000 Series chassis. The cards can be used in point-to-point, ring, multi-ring, or mesh topologies.

The SMR20 FS CV cards provide the connection verification capability using a connectivity check signal. The correctness and the quality of the interconnections (determined by measuring the insertion loss of the external passive path) can be validated with the connection verification feature in the cards . For more information about the connection verification, see Connection Verification section.

The EDFA pre-amplifier in SMR20 FS/SMR20 FS CV cards have switchable gain ranges. The following table describes the gain ranges and extended gain ranges of a EDFA pre-amplifier in the 17 SMR9 FS, 24 SMR9 FS, 34 SMR9 FS, and SMR20 FS/SMR20 FS CV cards.

Connection Verification

The SMR20 FS CV cards provide the connection verification feature. This feature measures power levels and verifies the optical cables and patchcords in a node for:

Connectivity: Checks whether the cable is connected.
Insertion Loss: Checks whether the cable loss is within expected value.

A 1567 nm connectivity check signal is generated and transmitted into the DE-MUX input port by a dedicated laser source. This signal, in turn, is detected by an embedded photo diode to complete the verification. The highlights of this feature are:

It validates the SMR20 FS CV card connection with other nodes or local Add/Drop elements.
It detects any incorrect cabling of the ROADM network element.
It collects insertion losses of every possible optical path inside the network element, in order to predict any possible failure.
It verifies the connection every six hours, by default. Refer to #http://www.cisco.com/c/en/us/td/docs/optical/15000r10_0/ncs/network_config/guide/b_ncs_network_configuration/b_ncs_network_configuration_chapter_010000.html#task_8B1E0075021B4A7EBCAC85FD09C02AC8 for manual validation of the SMR20 FS CV interconnections.

Note

In releases earlier to Release 10.8, the Connection Verification (CV) procedure terminates when the CV and circuit creation procedures that use the same wavelength, run concurrently on CV enabled cards. The wavelength that was used for CV is then auto-provisioned due to which the circuit creation uses a different wavelength.

Connection Verification Prerequisites

The connection verification works only if the following conditions are fulfilled:

Flex nodes must be present for the connection verification to work.
Loopback caps must be installed on all the unused ports of the passive modules.
At least one SMR20 FS CV card must be present in the node.
All sides of the node must have a SMR20 FS CV card to test all cables and patchcords.
All passive modules must be connected with an USB cable and associated, so that power readings can be calculated.

Supported Cards

The cards that supports connection verification are as follow:

16-AD-FS
SMR20 FS CV
MF-DEG-5 and MF-DEG-5-CV
MF-MPO-16LC and MF-MPO-16LC-CV
MF-PPMESH8-5AD
MF-UPG-4 and MF-UPG-4-CV

100GC-CK-LC and 200G-CK-LC

Note

Other MXP and TXP cards support CV partially; these cards support the CV for the patch cords belonging to paths going from TXP card trunk port to SMR20-FS-CV EXP-RX ports and not for the patch cords belonging to path in the opposite direction.
MF-DEG-5, MF-DEG-5-CV, MF-MPO-16LC, MF-MPO-16LC-CV, MF-PPMESH8-5AD, MF-UPG-4, and MF-UPG-4-CV cards require loopback caps on unused ports. The (-CV) version is shipped with the loopback pre-installed.

Running the Connection Verification

The connection verification runs:

Automatically at these time intervals and events:
- 20 minutes after first shelf controller boot or reboot
- One minute after enabling the connection verification
- Ten minutes after new patch-cord creation or deletion (*)
- Ten minutes after new circuit creation or deletion (*)
- Every six hours
For manual execution of connection verification, refer to #http://www.cisco.com/c/en/us/td/docs/optical/15000r10_0/ncs/network_config/guide/b_ncs_network_configuration/b_ncs_network_configuration_chapter_010000.html#task_8B1E0075021B4A7EBCAC85FD09C02AC8.

(*) indicates that this condition occurs only after an automatic run is interrupted by the creation or deletion of a circuit or a patch cord.
