Cisco NCS 1001 (NCS1001-K9) is 1 RU chassis that addresses the growing bandwidth needs of data center DWDM applications. It provides a DWDM line system that is optimized for data center environments and is optimized for point-to-point applications at maximum capacity. NCS 1001 supports up to three optical modules. The modules can be amplifiers or protection switching modules.

NCS 1001 has the following components:

• Removable control card

• Four removable fans

• Two removable 600W AC/DC or DC/DC power supply modules (PSU)

• Three slots for optical modules. Two Optical Amplifier Modules ( NCS1K-EDFA) and a Protection Switching Module (NCS1K-PSM) can be inserted in these slots.

  The optical modules can be inserted in slots 1 to 3 as shown in the following figure. The optical modules can be inserted and removed from the slots while the system is operational. In amplified configuration, the Optical Amplifier module can be inserted in any slot. In (section) protected configuration, the protect Optical Amplifier module is inserted in slot 1, Protection Switching Module in slot 2, and working Optical Amplifier module in slot 3.

Caution

Each optical module must be inserted in a slot only when the module in the adjacent slot is completely inserted and seated or the adjacent slot is empty. If an optical module is inserted in a slot without seating the adjacent module, the ejector might interfere with the adjacent module.

Caution

The empty slots must be inserted with the filler optical modules or filler PSUs as appropriate to guarantee safety and system cooling compliance. See Cisco NCS 1001 Front View and Cisco NCS 1001 Rear View to identify the slots for optical modules and PSUs respectively.

The slot numbers are also specified on the front panel label.

Both the power supply modules shall be AC/DC or DC/DC. Mixed configuration is not allowed.

Cisco NCS 1000 Series chassis is classified as Hazard Level 1M as per IEC 60825-2 and Laser Class 1M as per IEC 60825-1, since it includes pluggable optical modules Class 1 or Class 1M.

The Class 1/1M Laser Product label is shown in the following figure:

This section explains the significance of the safety labels attached to the NCS 1001 chassis. The faceplates of the chassis are clearly labeled with warnings about the laser radiation levels.

You must understand all warning labels before working on the chassis.

Safety Precaution for Module Installation and Removal

Ensure to observe the following safety precautions when you are working with the chassis modules.

Invisible laser radiations present. Statement 1016.

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051.

Safety Precaution for Laser Radiation

Cisco NCS 1000 Series chassis is classified as Hazard Level 1M as per IEC 60825-2 and Laser Class 1M as per IEC 60825-1, since it may include embedded or pluggable optical modules Class 1 or Class 1M.

The optical amplifier module (NCS1K-EDFA) has pre-amplifier and booster amplifier.

The optical amplifier module provides the following functionality.

• Preamplifier (LINE-RX to COM-TX) - Single preamplifier variant, with switchable gain ranges, according to link loss:

  • Range # 1: 0 to 24 dB gain, Tilt control: 24 to 27 gain, with tilt uncontrolled

  • Range # 2: 20 to 34 dB gain, Tilt control: 34 to 37 dB gain, with tilt uncontrolled

  • 23dBm output power @ COM-TX port

• Booster amplifier (COM-RX to LINE-TX) - True variable gain booster amplifier

  • Gain range: 1 to 20. 20 to 25 uncontrolled tilt.

  • 23dBm output power @ LINE-TX port

• ADD/DROP OSC channel supports both 1510nm and 1610nm +/-10nm

• OCM assesses channel presence and Gain regulation and per channel power monitoring.

The following table describes the mapping of controllers and optical ports for the optical amplifier module.

The protection switching module (NCS1K-PSM) provides the following functionality.

• In TX section:

  • Splits input optical channels to both working and protection lines.

  • Forces the switch in the remote site by opening one of the two line paths (by putting the related VOA in AVS).

• In RX section:

  • Selects the signals from working or protection line. Each line is monitored through a PD.

  • Balances the two line losses by changing the VOA attenuation value at the same time of the switch change of state.

The following table describes the mapping of controllers and optical ports for the protection switching module.

Optical Time Domain Reflectometer (OTDR) is a line card supported in NCS 1001. The line card contains 2x bidirectional OTDRs and 2x filter that combines C-band, OSC, and OTDR filters and splits OSC and OTDR. Each internal OTDR can perform measurements on both TX and RX fiber by using an internal optical switch. OTDR line card is connected to the OSC port on the optical amplifier. The OTDR line card can be inserted in any slot of NCS 1001.

For more information about the OTDR module, see the data sheet.

The Cisco NCS 1000 32-Channel Even Mux/Demux patch panel (PID: N1K-MD-32E-C) is a pair of passive Athermal Arrayed Waveguide Grating (AAWG) based modules.

Note	"Patch panel" refers to N1K-MD-32E-C Even Mux/Demux patch panel.

The patch panel has 32 channels and works as an add/drop unit for its 32 channels at 140 GBd. Each even patch panel allows the multiplexing and demultiplexing of 32 channels with 150-GHz spacing. The patch panel provides a wide spectrum of optical wavelengths support.

The N1K-MD-32E-C patch panel operates in C-band. This even patch panel is fully passive.

There are passive units that are part of NCS 1001 hardware configuration. It is possible to have information about these passive units as soon as they are connected with a proper USB cable through one of the four available USB ports on the controller card of the box itself.

In this case their basic parameters are displayed in the output of “show inventory” command by XR or admin session.

The following passive modules are supported in NCS 1001:

Remember

N1K-MD-32E-C and NCS1K-MD-32E-C are 32-channel even multiplexer/demultiplexer patch panels. The N1K-MD-32E-C does not have a loopback function and is compatible only with the NCS 1001. The NCS1K-MD-32E-C supports a loopback function and is compatible only with the NCS 1010.

When the supported passive module is connected to the front panel port of NCS 1001, the module is discovered and the inventory data is read from the USB device. The user can view the details of passive module such as PID, Description, Serial Number, and Version ID using the show inventory command. Only one passive unit information can be retrieved in the inventory of the box , if it is connected to the box itself through a cable to one of the available four USB ports.

The same parameter plus others are also obtainable in the response to SNMP get on “entPhysicalEntity” objects
