Note

QDD-400G-ZR-S and QDD-400G-ZRP-S are not supported on 8102-64H fixed-port routers.

QDD-400G-ZRP-S and DP04QSDD-HE0 are not supported on odd-numbered ports of the following routers and line cards:

  • Cisco 8201

  • Cisco 8202

  • 8800-LC-36FH

  • 88-LC0-36FH-M

The QDD-400G-ZR-S and QDD-400G-ZRP-S optical modules enable wavelength-division multiplexing (WDM) functionality in the router. These optical modules are DWDM C-band (196.1 THz to 191.3 THz) tunable optical modules. They can be used in both transponder and muxponder modes.

Cisco IOS XR software creates optics and coherent DSP controllers to configure and monitor the performance of the QDD-400G-ZR-S and QDD-400G-ZRP-S optical modules. Optics controllers are used to configure and monitor optical parameters, such as frequency, chromatic dispersion, transmitted output power, modulation, and so on. Coherent DSP controllers are used to monitor network performance parameters like pre- and post-forward error correction (FEC) bit-error rate (pre-FEC BER, post-FEC BER), error corrected bits (EC-BITS), and so on. Forward error correction (FEC) is configured using optical controllers and monitored using coherent DSP controllers.

The QDD-400G-ZR-S and QDD-400G-ZRP-S optical modules support traffic configuration and firmware download. The Cisco IOS XR software collects performance monitoring data and alarms using versatile DOM (VDM).

Due to more power consumption by the QDD-400G-ZR-S and QDD-400G-ZRP-S optical modules, the Cisco IOS XR software operates the fans at an higher speed to cool these optical modules.

The QDD-400G-ZR-S and QDD-400G-ZRP-S optical module configuration is divided into the following categories:

The following table contains the possible traffic configuration values for the QDD-400G-ZR-S and QDD-400G-ZRP-S optical modules, in the transponder and muxponder mode:

Configuring Frequency

You can configure frequency on optics controllers. You can select any C band frequency between the range 196.1 to 191.3 THz, in both ITU and NON-ITU channels.


Note

The 100MHz-grid keyword accepts only frequency values as user input. The 50GHz-grid keyword accepts frequency, ITU-channel, or wavelength values as user input. The Cisco IOS XR software then caculates the frequency for a given wavelength or ITU-channel.

Frequency Configuration Example

The following example shows how to configure frequency on the optics controller:
Router#config
Router(config)#controller optics 0/2/0/16
Router(config-Optics)#dwdm-carrier 100MHz-grid frequency 1921500
Router(config-Optics)#commit
Router(config-Optics)#exit
Router(config)#exit

Configuring Chromatic Dispersion

You can configure chromatic dispersion on optics controllers. When you configure the maximum and minimum values for chromatic dispersion for any data rate, ensure that the minimum difference between the configured values is equal to or greater than 1000 ps/nm.

Configuring Optical Transmit Power

You can set the transmit power of the optical signal.

Each QDD-400G-ZR-S and QDD-400G-ZRP-S optical module has its own optical transmit (TX) power range. You can change the optical transmit (TX) power value based on the module capability. For "Transmitter specifications", see the Cisco 400G Digital Coherent Optics QSFP-DD Optical Modules Data Sheet.

Configuring Muxponder Mode

By default, the Cisco IOS XR software configures the QDD-400G-ZR-S and QDD-400G-ZRP-S optical modules in the 400G transponder mode.

Using the breakout muxponder mode command, you can configure muxponder mode on optics controllers. Based on the muxponder mode, you can choose the modulation.

Muxponder mode options available for QDD-400G-ZR-S are:

  • 4x100

Muxponder mode options available for QDD-400G-ZRP-S are:

  • 4x100

  • 3x100

  • 2x100


Note

Release 7.3.15 supports only 4x100 muxponder mode.

See the following tables for the modulation values, based on the muxponder mode:

Using the no breakout muxponder mode command, you can switch from the muxponder mode to the transponder mode, on optics controllers.

Muxponder Mode Configuration Example

The following example shows how to configure muxponder mode on the optics controller:
Router#config
Router(config)#controller optics 0/0/0/13
Router(config-Optics)#breakout 4x100
Router(config-Optics)#commit
Router(config-Optics)#exit
Router(config)#exit

Note

In the above example, the Cisco IOS XR software creates four Ethernet clients with 100GE speed, which can be verified using the show interfaces brief | include R/S/I/P command.

Running Configuration

This example shows the running configuration for the optics controller: 

Router#show run controller optics 0/0/0/13

Transponder Mode Configuration Example

The following example shows how to switch to the transponder mode, on the optics controller:
Router#config
Router(config)#controller optics 0/0/0/13
Router(config-Optics)#no breakout 4x100
Router(config-Optics)#commit
Router(config-Optics)#exit
Router(config)#exit

Note

The Cisco IOS XR software creates a single 400GE interface, which can be verified using the show interfaces brief | include R/S/I/P command.

Configuring Modulation

You can configure modulation on optics controllers. Based on the muxponder mode, you can choose the modulation.


Note

The system accepts any modulation value that is entered. However, if the modulation value is outside the supported range, it is not configured on the optical module. Instead, the optical module is auto-configured with a valid modulation value. To view this value, use the show controller optics R/S/I/P command.

See the following tables for the supported modulation values:

Modulation Configuration Example

The following example shows how to configure modulation on the optics controller:
Router#config
Router(config)#controller optics 0/0/0/1
Router(config-Optics)#modulation 16Qam
Router(config-Optics)#commit
Router(config-Optics)#exit
Router(config)#exit

Note

Use the show controller optics R/S/I/P command to verify the modulation value of the optical module.

Configuring DAC Rate

You can set the DAC (digital to analog conversion) sampling rate on optics controllers. You can modify the DAC sampling rate only on the QDD-400G-ZRP-S optical module.


Note

QDD-400G-ZR-S supports 1x1 dac-rate in cFEC mode. QDD-400G-ZRP-S supports 1x1 dac-rate in cFEC mode and 1x1.25 dac-rate in oFEC mode.

Configuring FEC

You can configure forward error correction (FEC) only on optics controllers. You can modify FEC only on the QDD-400G-ZRP-S optical module. FEC is a feature that is used for controlling errors during data transmission. This feature works by adding data redundancy to the transmitted message using an algorithm. This redundancy allows the receiver to detect and correct a limited number of errors occurring anywhere in the message, instead of having to ask the transmitter to resend the message.


Note

QDD-400G-ZR-S supports cFEC (concatenated forward error correction). QDD-400G-ZRP-S supports cFEC and oFEC (open forward error correction).

FEC Configuration Example

The following sample shows how to configure FEC on the optics controller:

Router(config-Optics)#fec CFEC

Configuring Loopback

You can configure internal or line loopback on coherent DSP controllers. Loopback can be performed only in the maintenance mode.

Loopback Configuration Example

This example shows how to enable internal loopback configuration on coherent DSP controllers: 

Router#config

Router(config-CoDSP)#secondary-admin-state maintenance
Router(config-CoDSP)#loopback internal
Router(config-CoDSP)#commit

Configuring Performance Monitoring

Performance monitoring (PM) parameters are used by service providers to gather, store, set thresholds for, and report performance data for early detection of problems. The user can retrieve both current and historical PM counters for the various controllers in 30-second, 15-minute, and 24-hour intervals.

Performance monitoring can be configured on optics controllers and coherent DSP controllers.

To stop performance monitoring on optics or coherent DSP controllers, use the perf-mon disable keyword.

Configuring PM Parameters

The performance monitorning (PM) threshold and the threshold crossing alert (TCA) reporting status can be configured for optics controllers and coherent DSP controllers:
