Teaches you how to modify fiber properties. Follow these detailed step-by-step instructions carefully to ensure the specific configuration is applied correctly and securely within your network.

Use this procedure to modify the properties of a fiber.

Before you begin

Log in to the Cisco ONP web interface

Procedure

  1. Open the network where you want to modify the fiber properties.

    When you click a fiber on the map, it will be highlighted in orange

  2. Choose Network > Entity Editor.

  3. Click the Fiber tab in the Entity Editor window.

  4. Choose the fiber and modify the required properties. For the property descriptions, refer to:

  5. Click Update.

Length

NCS 2000

NCS 1010

NCS 1001

Displays the span length of the fiber connecting a source and destination site. If necessary, change the span length manually.

  • The Cisco ONP tool automatically updates the fiber length to 1 km or 1 mile. If you change the fiber length, then the tool updates the same in the network tree and the map accordingly.

  • In the network tree pane, expand Fiber and select the fiber couple, A-Z and Z-A. The properties pane displays the fiber couple name, source side, destination side, its span length, loss, and, Polarization Mode Dispersion (PMD) value.

  • You can enter the different span length and loss values for the individual fibers in a fiber couple.
