Cisco High-Power QSFP-DD ZR+

Cisco 400G QSFP-DD High-Power (Bright) Optical modules are high Tx power variants (+2dBm of Tx Power) of the 400G QSFP-DD.Modules.

These high-power optical modules allow easier interoperability with all deployed Add/Drop architectures and enhance unamplified reach by about 12dB as compared to QDD-400G-ZR-S and QDD-400G-ZRP-S. The optical specifications of these Bright ZR+ pluggables are aligned with current OpenZR+.

Cisco Bright QSFP-DD ZR+ modules operate at a default TX power of +1 dBm for all platforms. Unlike ZR/ZR+ TX power level at all speeds and modulations remain at +1 dBm. Configuring the FEC type to cFEC reduces power to -10dBm for ZR compatibility. Cisco Bright QSFP-DD ZR+ modules support the same modes as QDD-400G-ZRP-S -10dBm optics.

Two product variants are available:

  • Ethernet Variant (DP04QSDD-HE0)

  • Multirate OTN/Ethernet Variant (DP04QSDD-HK9)

Cisco 400G QSFP-DD High-Power (Bright) Optical Module Ethernet Variant

Cisco 400G QSFP-DD High-Power (Bright) Optical module Ethernet variant is an enhanced version of the currently available QSFP-DD ZR+ Optical Module leveraging the same operational modes but providing as a major enhancement the increase of the Tx Optical Power up to +2dBm.

Supported client interface for this pluggable is Ethernet based, making this model perfectly suitable to be hosted on a router/switch host. The module asynchronously (GMP) maps an Ethernet signal from a switch/router to an intermediate 400ZR frame structure and then adapts the frame structure to the appropriate FEC engine. The encoded signal is then DSP framed and modulated for transmission as a coherent Dual-Polarity mQAM signal. The PID for this pluggable optical module is DP04QSDD-HE0.

In Cisco IOS XR Release 7.9.1, the following routers support Cisco Bright QSFP-DD ZR+.

  • NCS-57C3-MOD

  • 8201-32FH

  • 8201-24H8FH

  • A9K-20HG-FLEX-SE/TR

  • A9K-8HG-FLEX-SE/TR

From Cisco IOS XR Release 7.10.1, all NCS-5500 and NCS-5700 platforms support Bright ZR+ support Cisco Bright QSFP-DD ZR+.


Note


NCS-55A2-MOD-S(E)-S with MPA-2D4H support Bright ZR+ from Cisco IOS XR Release 7.11.1.


Cisco 400G QSFP-DD High-Power (Bright) Optical Module Multirate Ethernet/OTN Variant

The Cisco 400G QSFP-DD High-Power (Bright) Optical module multirate Ethernet/OTN variant shares the same HW platform (and so also the high Tx power) of the Ethernet variant but also supports OTN clients. The module leverages an intermediate ODUFlex, OTUCn/FlexO-x frame structure and then adapts the frame structure with OFEC.

This variant, thanks to the OTN OH, supports Layer-1 (L1) functionality to support authentication and encryption/decryption of the OPU[Cn,4] payload. The security IP provides wire-speed Galois-Counter- Mode (GCM) AES 256-bit security in either authentication-only (GMAC) or encryption/decryption-only (CTR) modes or both (GCM). Interhost key exchange is supported via communication over the GCC channel.

For more information on Bright ZR+ Optical Modules, see the Cisco 400G QSFP-DD High-Power (Bright) Optical Module Data Sheet.

Legacy 200G Modulation Modes

Cisco ZR+ modules support a ZR+ Legacy mode in 200G-8QAM 40Gbaud and 200G-16QAM 30GBaud modes. These modes allow 200G rate to fit within a 50Ghz spaced optical system. In the default mode, the modules operate in 200G QPSK at 60Gbaud.

OpenZR+ Compatibility Mode

Cisco QDD-400G-ZRP-S and DP04QSDD-HE0 modules have an OpenZR+ MSA compatibility mode. This mode:

  • Sets modem mode to standard

  • Is set by configuring optics controller Dac-Rate to

    • 1x1 for 400G, 300G, and 200G trunkrates on ZR+

    • 1x1.5 for all trunkrates on Bright ZR+ and 100G trunk rate on ZR+

  • Is used to interoperate with ZR+ optics from other vendors


Note


Setting a DAC rate of 1x1 disables TX shaping as it affects the TX power levels.

Cisco QSFP-DD Pluggable Open Line System

The QSFP-DD OLS is a pluggable open line system solution that can be directly hosted on a Cisco router. The Cisco QSFP-DD Open Line System (QSFP-DD OLS) is a pluggable optical amplifier module that, together with the channel breakout options, provides a simple yet powerful open line system solution in a pluggable form factor that can be directly hosted on a Cisco router.

The following routers support Cisco QSFP-DD Pluggable Open Line System Modules (QSFP-DD OLS) from Cisco IOS XR Release 7.10.1:

  • NCS-57B1-6D24-SYS

  • NCS-57B1-5DSE-SYS

  • NCS-57C3-MOD (using NC57-MPA-2D4H-S modular port adapter)

  • NCS-55A2-MOD (using NC57-MPA-2D4H-S modular port adapter)

The QSFP-DD OLS itself is a pluggable module that integrates in itself two variable-gain amplifiers: a pre-amplifier and a booster amplifier to amplify both the up and down fiber streams. Various channel breakout options are available to combine or separate each channel from a coherent DWDM optical source. The TX-EDFA acting as a Booster amplifier recovers the loss of the optical Multiplexer units, and it provides an optical power boost before the link. The RX-EDFA acting as Preamp recovers the link loss, bringing the optical signal to a power level above the sensitivity of the receivers after the Demultiplexer unit.

The QSFP-DD OLS can extend the reach of a 400G QSFP-DD ZR/ZR+ link from 40 to 130 km or longer depending on fiber specification, the channel count, and the line rate of the signal.

The QSFP-DD OLS can extend the reach of a 400G Bright QSFP-DD ZR/ZR+ link from 80 to 130 km or longer depending on fiber specification, the channel count, and the line rate of the signal.

To be able to integrate a pair of ingress and egress ports on the QSFP-DD OLS pluggable faceplate, industry-standard CS connectors are used. The QSFP-DD-OLS has two bidirectional optical ports: the COM-RX/TX that shall be connected to the Mux/DMX unit, and the LINE-TX/RX that shall be connected to the fiber link. The optical connectors are 2x CS-UPC. The CS connector provides the characteristics and simplicity of the duplex LC connector into a smaller footprint to allow two pairs of CS connectors to fit within the physical constraints of the QSFP-DD form factor. Since the other optical units like Coherent Interfaces modules, DWDM Add/Drop multiplexers, and fiber patch panels have normally LC connectors, a hybrid adaptation patch cord with a CS dual connector on one side and 2x LC connector on the other side is available to interconnect the QSFP-DD-OLS modules with other optical equipment.

Optical safety is enabled by default to:

  • Switch off each section independently in case Optical LOS is detected at its input.

  • Set the TX-EDFA in Automatic Power Reduction (APR) at 8dBm in case a LOS is cleared at the COM-RX port, but LOS is still present at LINE-RX (this prevents the launch of high optical power on an open line)

One can build an N-channel line system using the QSFP-DD OLS and its associated components:

A single channel system

It requires no special components to add and drop. A special CS-LC cable (ONS-CAB-CS-LC-5) has been made available to interconnect LC ports of the QSFP-DD coherent source or the network with the CS ports of the QSFP-DD OLS. Just one pair of these cables is sufficient to make a single channel system. All the gain of the amplifier is available for the single channel in focus.

A 4-channel system

To achieve a 4-channel combine and split, an FLD-4 (fixed 4 channel OADM) can be used. This is a passive optical Add/Drop unit belonging to the ONS-15216 platform that is able to multiplex/demultiplex 4 channels over the 100GHz ITU grid.

An 8-channel system

To achieve an 8-channel combine and split, a 1x8 channel breakout cable can be used. This new breakout cable (ONS-BRK-CS-8LC) is a dual fanout 1x8 cable with an embedded passive splitter and coupler. The cable is grid-less so any port can be fed with any optical frequency without any constraints of frequency value or spacing between the channels.

A 16-channel system

To achieve a 16-channel combine and split, a 1x16 channel breakout cable can be used. This new breakout cable (ONS-BRK-CS-16LC) is a dual fanout 1x16 cable with an embedded passive splitter and coupler. The cable is grid-less so any port can be fed with any optical frequency without any constraints of frequency value or spacing between the channels.

A 32-channel system

To achieve a 32-channel combine and split, a 64-channel mux/dmx can be used (of which 32 channels are used). This (NCS1K-MD-64-C) is passive optical Add/Drop unit belonging to the NCS1K platform able to multiplex/demultiplex up to 64 channels over the 75GHz grid. Due to the limited operating bandwidth of the QSFP-DD-OLS, only a subset of the MD-64 channels can be used: from port CH-19 (194.75 THz) to port CH-50 (192.425 THz).

SVO enables end-to-end, software-defined automated networks that maximize revenue to customers and ease the network turn-up, operation, and maintenance.

SVO is available with a server on a blade encasing a high-speed processor with virtualized instances of multiple reconfigurable optical add/drop multiplexer (ROADM), optical line amplifier (OLA), and dynamic gain equalizer (DGE) sites of the network. An SVO line card along with the application software provides functionality-based licenses for alarm correlation, performance monitoring, connection verification, and optical time domain reflectometry (OTDR).

The Cisco NCS 2000 SVO helps to maintain and improve customers’ profitability with the orchestration of network elements and their functionalities. SVO allows the network elements to do only forwarding functions. SVO maintains the configuration and monitoring of the same at the node level with a centralized controller.

For more information on Cisco NCS 2000 Shelf Virtualization Orchestrator, see the Cisco NCS 2000 Shelf Virtualization Orchestrator Data Sheet.

Control Cards

Cisco NCS 2000 Series Transport Node Controller 2 with Optical Time Domain Reflectometry (TNCS-2O) Card performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP addressing, Data-Communications-Channel (DCC) termination, monitoring of system input voltage, system fault detection, and multishelf management connections. Optical Time Domain Reflectometry (OTDR) is used to provide information about the basic characteristics of the Optical fiber among Optical nodes, such as insertion loss, concentrate-point of reflection, fiber-to-fiber connection losses and reflectance.

For more information on Cisco Transport Node Controller and Transport Shelf Controller Cards, see the Cisco Transport Node Controller and Transport Shelf Controller Cards Data Sheet.

ROADM Cards

The 20-SMRFS card is 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 gives the flexibility to allocate channel bandwidth and increase the network scalability. With flex capability, the channel bandwidth is not fixed, but can be defined arbitrarily, with a specified granularity and within a given range. The card makes the network flexible as it allows you to reconfigure the optical channels on the run.

The 20-SMRFS card is a single-slot card that integrates two cross-connect blocks (multiplexer and demultiplexer), a variable-gain EDFA preamplifier, and a variable-gain EDFA booster amplifier. The card supports up to 20 directions for each ROADM node. The EDFA preamplifier in this card has gain ranges of 0–17 and 12–24 dB with controlled tilt and extended gain ranges of 20 dB and 35 dB with uncontrolled tilt.

For more information on Cisco NCS 2000 Flex Spectrum Single Module ROADM Line Cards, see the Cisco NCS 2000 Flex Spectrum Single Module ROADM Line Cards Data Sheet.

Amplifier Cards

The Cisco NCS 2000 offers enhanced optical amplifier cards operating in the C-band region of the optical spectrum to extend the reach and capacity of a metro, regional, or long-haul network. The optical amplifier cards are part of the Cisco NCS 2000 intelligent DWDM architecture that is engineered to reduce DWDM complexity and speed the deployment of next-generation networking solutions.

EDFA Cards

The OPT-EDFA-17 and OPT-EDFA-35 cards are C-band DWDM EDFA amplifiers and preamplifiers. The cards are true variable gain amplifiers, offering an optimal equalization of the transmitted optical channels over a wide gain range. They support 96 channels at 50-GHz channel spacing in the C-band (that is, 1528.77 to 1566.72-nm wavelength range). The OPT-EDFA-17 card delivers 20-dBm output power. The OPT-EDFA-35 card delivers +23-dBm output power. These cards do not contain midstage access loss for a Dispersion Compensation Unit (DCU). The cards provide a noise-figure optimized version of the EDFA amplifiers to cope with new modulation formats like PM-DQPSK, which do not need dispersion compensation.

For more information on Enhanced C-Band 96-Channel EDFA Amplifiers for the Cisco ONS 15454 Multiservice Transport Platform (MSTP), see the Enhanced C-Band 96-Channel EDFA Amplifiers for the Cisco ONS 15454 MSTP Data Sheet.

EDRA Cards

The double-slot EDRA-2-26 card combines standard erbium-doped fiber amplifiers and a Raman amplifier to enable amplification on long unregenerated spans. These plug-in modules support an ultra-low noise figure that is critical for long-distance, high-bit-rate transmission. Supporting 96 channels in the C-band (wavelengths from 1528.77 to 1566.72 nm), they provide the reach and optical performance required to meet the most demanding distance requirements of service provider and enterprise DWDM networks. EDRA-2-26 includes an erbium-doped preamplifier, EDFA1, with a nominal gain of 14 dB and an erbium-doped booster amplifier, EDFA2. It supports a maximum span of 26 dB on standard single-mode fiber.

The Cisco® ONS 15454 Multiservice Transport Platform (MSTP) High-Power Counter-Propagating Raman Amplifiers operate in the C-band region of the optical spectrum to extend the reach and capacity of regional, long-haul, and ultra-long-haul optical.

Raman amplifiers use the intrinsic properties of silica fiber in such a way that the transmission fibers themselves become a medium for amplification. This approach allows the attenuation of data signals transmitted over the fiber to be mitigated within the fiber itself. An amplifier using this principle is commonly known as a distributed Raman amplifier or simply, a Raman amplifier. The high-power counterpropagating unit injects counterpropagating optical power to generate a Raman effect in the span fiber and thus amplifies the signals propagating in the same fiber.

The single-slot RAMAN-CTP card supports counter Raman amplification on long unregenerated spans. The cards manage up to 96 ITU-T 50 GHz spaced channels over the C-band of the optical spectrum (wavelengths from 1528.77 to 1566.72 nm).

The inter-layer link services are user-defined. Flex-port mapping and transceiver capabilities are installed as part of the function pack, but can be modified by the user.


The Routed Optical Networking ML service connects two DWDM optical ports with a fixed bandwidth of either 100, 200, 300, or 400G between the routers. This service is characterized by a single DWDM wavelength.

The Routed Optical Networking ML service helps to:

  • Provision line card modes to support 400G optics

  • Configure the optical parameters on the ZR or ZR+ optics

  • Assign IP address to Ethernet interfaces or bundle interfaces

  • Bundle discrete Ethernet interfaces

Cisco Evolved Programmable Network Manager

The Cisco Evolved Programmable Network Manager (EPNM) is an all-in-one management solution for today’s converging packet and optical networks.

Cisco EPN Manager supports the Cisco Routed Optical Network architecture and delivers Cisco Optical and IP full device management and Cisco optical circuit network assurance. The Cisco EPN Manager discovers and represents the physical and logical configuration of managed devices.

Cisco EPN Manager provides full software image management and configuration management for the Cisco optical and IP devices.

A graphical chassis view with status indications gives network operators a live-live view of the device. EPNM differentiates itself from other network management systems with the ability to discover optical circuit from the network and maintain up-to-date representation of the optical circuit and the infrastructure dependency.

EPNM helps reduce the time to know about network or optical circuit-affecting conditions by correlating raw events and associating alarm conditions with affected managed network elements, network connectivity, and circuit. Contextual dashboards and 360-degree views (device and port levels) display the most relevant information for fast and efficient problem identification and remediation. To help reduce the time to restore and repair, EPNM guides the troubleshooting process using alarm correlation, identification of affected components or optical circuit, and connectivity. EPNM collects fault and alarm information, and performs node-level performance measurement statistics collection.

IOS-XR Software Components

Cisco IOS XR is a modern and flexible network operating system. XR improves operational efficiencies with management API integration to provide near real-time, actionable telemetry data. Two features of IOS XR that enable Routed Optical Networking are:

  • YANG-modeled management layer APIs: To automate device provisioning and management. These models include native IOS XR YANG models and OpenConfig models.

  • Streaming telemetry capabilities: For cadence-based or event-driven monitoring of data that is derived from YANG-modeled paths in the manageability layer over gRPC, TCP, or UDP.

Data models provide an alternate centralized way to configure devices instead of using the CLI or SNMP and to collect operational data from Cisco devices. Because the data models are standards-based, the same procedures are able to configure or collect data from non-Cisco devices as well. This ability makes them ideal for customers that support multiple vendors. You can use a centralized management platform to configure or collect data from multiple Cisco devices. The data model architecture allows for automating these procedures.

Network Configuration (NETCONF) Protocol

NETCONF is a standard-based and XML-encoded protocol. NETCONF provides the transport to communicate YANG formatted configuration or operational data requests from an application, which runs on a centralized management platform, to the Cisco device that you wish to configure or request operational data from. It provides transaction-based services, such as aborting the entire configuration request when a portion of that configuration request fails.

NETCONF uses a simple Remote Procedure Call based mechanism to facilitate communication between clients (centralized management platform script or application) and servers (Cisco switch or router). It uses SSH as the transport layer across network devices.

Yet Another Next Generation Data Modeling Language

YANG is a standards-based data modeling language. You can use YANG to create device configuration requests or requests for operational (show commands) data. It has a structured format similar to a computer program that is human-readable. Several applications that can run on a centralized management platform to create these configuration and operational data requests are available.

There are two types of YANG models:

  • Standard (common) YANG data model that applies to all vendors. (For example, a request to disable or shut down an Ethernet interface is identical for both Cisco and non-Cisco devices.)

  • Device (native, vendor-specific) data models that facilitate configuring or collecting operational data concerning proprietary vendor features.

This table lists Cisco native models, their Open Config equivalents used in the Routed Optical Networking solution and their functions.

Note


  • openconfig-terminal-device configures logical hierarchy of connections from ingress to egress. For Cisco optical devices, you can use OpenConfig to configure nx100G muxponder or transponder modes, and trunk rate.

  • Use openconfig-platform to configure the physical layer parameters:

    • Frequency

    • TX power

    • Operational-mode (Modulation, FEC, and TX shaping)

  • See Managing OpenZR+ and OIF ZR transceivers on Cisco routers using OpenConfig for info on managing pluggable digital coherent optics using OpenConfig.


Model Driven Telemetry

Telemetry is an automated communications process that you use to collect measurements and other data at remote or inaccessible points and transmit to receiving equipment for monitoring. Model-driven telemetry (MDT) provides a mechanism to stream YANG-modeled data to a data collector. Model-driven telemetry allows network devices to continuously stream real-time configuration and operating state information to subscribers.

Applications can subscribe to specific data items they need, by using standards-based YANG data models over NETCONF, RESTCONF, or gRPC Network Management Interface (gNMI) protocols. You can also create subscriptions by using CLIs if they are configured subscriptions. Devices publish structured data at a defined cadence, or on-change, based on the subscription criteria and data type. See Troubleshoot Provisioning Issues for information on telemetry sensor paths and corresponding data fields.

MDT leverages structured data models that the networking device supports. MDT provides critical data that is defined in those data models. Telemetry helps you to manage your multivendor network using a common network management system, a process, and applications. The data that is collected from the network are standards-based and are uniform across vendor implementations.
