Manual Editing of Raman COP values

Cisco ONP Release 4.1

This feature allows you to edit the crosstalk values of the Raman COP amplifier in the SSON network, starting from NCS 2000 Release 11.1.

Feature Description

Inline Amplifier

Cisco ONP Release 4.2

The Inline Amplifier option allows you to enable an inline amplifier in the network. You can simulate the optical feasibility of the network with and without an inline amplifier. Based on the colorless or colored add/drop type selected and the QSFP-DD pluggable status, a default inline amplifier is enabled for the network.
Note

Make sure that SMR card is forced on the site before you update the c-band amplifier properties.

Procedure

1.

Open the network where you want to modify the C-band properties.
2.

Choose Network > Entity Editor.

Alternatively, click the network name in the network tree, and click Show Advanced Properties displayed under the network tree.

In the Entity Editor window, click the Site tab.
4.

Choose Sites > Site > Site domain > Side > C-Band.
5.

Click C-Band Amplifier and modify the properties. For detailed property descriptions, refer to:

Inline Amplifier

NCS 2000

Choose whether inline amplifier can be forced.

Note

When you configure MF-6AD-CFS+EDFA35 in an SSON or non-SSON network, the optical results show system error for the demands of the same or different types. This error affects the what-if analysis. Hence we recommend choosing the appropriate channel and client attenuators so that the inline amplifier works at the proper gain range.

You can view the amplifier added in the IPC, BOM, and Layout tabs, after the successful analysis.

Note

  • When you add a QDD demand while upgrading a network where the Inline Amplifier property is set as no, the inline amplifier can be included in the network only if you unlock the side and set the Inline amplifier property as Auto or Yes.

  • Default colorless configuration does not require inline amplifier.

  • When there are no demands passing through the colored or colorless Add/Drop device, the forced Inline amplifier is not placed.

  • Yes―EDFA17 or EDFA35 amplifier is chosen as the default amplifier when you choose colored add/drop module MD-64-C or colorless add/drop MF-6AD-CFS, respectively. See Modify Add/Drop multiplexer properties.

  • No―No amplifier can be forced.

  • Auto

    • EDFA17 amplifier is chosen as the default amplifier when any one of the demands aggregated in MD-64-C has low launch power optical resource or QSFP-DD pluggable is forced.

    • EDFA35 amplifier is chosen as the default amplifier when any one of the demands aggregated in MF-6AD-CFS has low launch power optical resource or QSFP-DD pluggable is forced.

Raman Amp

NCS 2000

Choose the Raman amplifier from the drop-down list.

Note

To force the RAMAN amplifier on NCS 2000 node, you must enable RAMAN amplified on the fiber, else the Raman Amp is disabled, and network analysis fails.

Note

When you enable the fiber property Raman amplified and the side property Enable C+L Band S/C for NCS 2000 node, Raman Amp is automatically forced as RAMAN-C+L.

The available options for NCS 2000 ROADM and Traffic sites are:

  • Auto

  • RAMAN-CTP

  • RAMAN-COP-CTP

    Raman Amp can be forced only between two nodes.

  • Auto

  • EDRA1-26

  • EDRA1-35

  • EDRA2-26

  • EDRA2-35

  • RAMAN-CTP
