RAMAN-CTP and RAMAN-cop cards

In this chapter, "RAMAN-CTP" refers to the 15454-M-RAMAN-CTP card and "RAMAN-COP" refers to the 15454-M-RAMAN-COP card.

The single-slot RAMAN-CTP and RAMAN-COP cards support counter and co-propagating 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 counter-propagating RAMAN-CTP card is the primary unit. The co-propagating RAMAN-COP card is the secondary unit and can be used only when the counter-propagating unit is present. The OSC pluggable used with the cards is ONS-SC-OSC-18.0=.

The RAMAN-CTP card can be calibrated either manually or automatically from the Maintenance tab in the Cisco Optical Site Manager web interface. When the RAMAN-COP card is used, the RAMAN-CTP card can be calibrated only using the manual option.

The features of the RAMAN-CTP and RAMAN-COP cards include:

  • Raman section: 1000-mW total pump power for four pumps and two wavelengths.

  • Embedded distributed feedback (DFB) laser at 1568.77 nm to be used for optical safety and link continuity (in RAMAN-CTP card only).

  • Photodiodes to enable monitoring of Raman pump power.

  • Photodiodes to enable monitoring of the DFB laser and signal power (in RAMAN-CTP card only).

  • Automatic laser shutdown (ALS) for optical laser safety.

  • Hardware output signals for loss of signal (LOS) monitoring at input photodiodes.

  • Raman pump back reflection detector to check for excessive back reflection.

When the node has either RAMAN-CTP or RAMAN-COP card, you can install the card in the following slots.

  • Slots 2-7 in NCS 2006

  • Slots 2-16 in NCS 2015

When the node has both RAMAN-CTP or RAMAN-COP cards, you can install the cards in the following slots.

  • If the RAMAN-CTP card is installed in an even slot, the RAMAN-COP card must be installed in the next odd slot.

  • If the RAMAN-COP is installed in an even slot, the RAMAN-CTP card must be installed in the next odd slot.


RAMAN-CTP and RAMAN-cop cards power monitoring

Physical photodiodes P1 through P10 monitor the power for the RAMAN-CTP card.

Physical photodiodes P3 through P6 monitor the power for the RAMAN-COP card.

For more information about the RAMAN-CTP and RAMAN-COP cards, see the data sheet.

Clear the Raman laser shutdown condition

Use this task to clear the Raman laser shutdown condition.

The Raman Laser Shutdown (RLS) condition is raised during the Raman link turn-up phase on the RAMAN-TX port of the RAMAN-CTP and RAMAN-COP cards when excessive back reflection is detected. When the RLS condition is raised, the Raman pump laser inside the card is automatically shut down and the optical link turn-up procedure is terminated. The RLS condition must be cleared before proceeding with further provisioning.

Use this task to clear the RLS condition for RAMAN-CTP and RAMAN-COP cards.

Before you begin

Follow these steps to clear the Raman laser shutdown condition.

Procedure

  1. Click the Maintenance > Safety tabs.

  2. Click Manual Safety Restart to clear the RLS condition.

    A confirmation dialog box appears and is service-affecting.

  3. Click Yes to proceed.

The clear the Raman laser shutdown condition task is complete.

    Incoming Power Pumps Off (dBm)

    Displays the power level of probe signal with Raman pumps off.

    Incoming Power Pumps On (dBm)

    Displays the power level of probe signal with Raman pumps on (combined with Raman noise floor).

    • Broadband Optical Power-Raman automatic calibration used broadband optical power, typically, Amplified Spontaneous Emission (ASE) generated by an optical amplifier.

    • Active Optical Services-Raman automatic calibration used active services.

    • Active Optical Services (Unbalanced)-Raman automatic calibration used active services;however, they do not properly cover the whole C-Band spectrum.

    Result

    Displays the result of automatic Raman calibration. The possible values of Result are as follows:

    • No Target Gain-Raman target gain is not configured.

    • Not Enough Gain-Raman gain obtained from calibration is too low.

    • Lower Than Target Gain (Need Accept)-Raman gain obtained from calibration is below the target but might be acceptable. The user must accept the Raman gain.

    • Lower Than Target Gain ( Accepted)-Raman gain obtained from calibration is below the target and the user has accepted the Raman gain.

    • Target Gain Reached-Raman target gain is reached.

    • User Override-User has overridden the calibration result and uses configured setpoint of Raman pumps manually.

    Status

    Displays the status of automatic Raman calibration. The possible values of Status are as follows:

    • Not Scheduled-Raman automatic calibration is not scheduled.

    • Invalid-Raman automatic calibration reports invalid data.

    The calibration result can be success, failure, or lower than target gain.

    • If the calibration result is success, the obtained target gain value is applied to the node.

    • If the calibration result is failure, the old target gain value is restored.

    • If the calibration result is lower than target gain, it implies that the obtained gain is + or -2 dB from the target gain. The gain is degraded. The RAMAN-GAIN-NOT-REACHED alarm is raised on the node to inform the user of a lower target gain. The user can accept this lower target gain by clicking the Accept Degraded Gain button. This clears the RAMAN-GAIN-NOT-REACHED alarm and the lower target gain value is applied to the node.

  4. (Optional) (Not applicable for RMN-CTP-CL card) Click Get All Calibration Reports to display the last 10 calibration reports with the timestamp and result in a table.

  5. (Optional) Click Get Last Calibration Error to identify the reason for the last calibration failure.

    The automatic calibration typically completes without user intervention. However, the automatic calibration fails upon certain conditions such as loss of communication between two nodes and OSC failure. You can identify the reason for the last calibration failure by clicking the Get Last Calibration Error button. The reason is displayed only when the Status column in the Automatic Calibration tab is Failure.

The perform automatic calibration task is complete.

Provision FPD upgrade

Use this task to provision FPD upgrade.

Whenever the firmware version on the card is earlier than the FPGA firmware version, an alarm "FPD-UPG-REQUIRED" is raised on the card in the Alarms tab.

You can view the running firmware version and the NCS 2000 FPGA firmware version under the Maintenance > FPD upgrade tabs.

Use this task to upgrade the RMN-CTP-CL card with the latest firmware released as part of the NCS 2000 software release.

Before you begin

Follow these steps to provision FPD upgrade.

Procedure

  1. Click the Maintenance > FPD Upgrade tabs.

  2. Click FPD upgrade to perform firmware upgrade for the card.

    After the firmware upgrade is completed successfully, the "FPD-UPG-REQUIRED" alarm gets cleared in Alarms tab and you can view the updated running firmware version in the FPD Upgrade table.
