Detailed View in NFV for Transponder and Muxponder Card on Third-party OLS Networks 

Cisco IOS XR Release 24.2.1

The Node Functional View (NFV) has been enhanced to provide a detailed view of transponder and muxponder cards on NCS1014 deployed within networks utilizing third-party Optical Line Systems (OLS).

This detailed view provides a graphical representation of the connections between the trunk and client ports on the transponder and muxponder cards, thereby simplifying the visualization of the network's connection layout.

Detailed View in NFV for Transponder and Muxponder Cards on OLS Networks

Cisco IOS XR Release 24.1.1

You can now access a detailed graphical representation of the connections between the trunk and client ports of the transponder and muxponder cards on Optical Line System (OLS) NCS 1010 networks. This is available in the Map View of Node Functional View (NFV).

This view is based on the card mode configured on the cards. When you access the detailed view, the right-panel of the Node Functional View displays the card mode details and a list of ports and their settings.

Understanding Node Functional View

The Node Functional View (NFV) provides a visual representation of a network rack, including the node and its associated components, such as cards and chassis. You can also add or manage chassis and passive units, switch between different views, and explore detailed maps of physical connections.

Additionally, NFV enables interaction between the Map and Rack views, allowing you to highlight and zoom in on specific components and their connections, such as optical cross-connections and port details.

Table 4. OTDR Scan Sensitivity and Threshold

Use this option

to

Loss Sensitivity

enable the OTDR scan to detect small signal losses (attenuation) along the fiber. Higher loss sensitivity helps the OTDR identify minor attenuation caused by factors like bends or splices.

Reflection Sensitivity

enable the OTDR scan to detect reflected signals from events such as connector interfaces, splices, or breaks.

High reflection sensitivity is crucial for accurately locating and analyzing reflective faults in the fiber.

Absolute Threshold

ensure that the OTDR scan can reliably detect and measure the lowest signal strength, allowing the OTDR to provide accurate and meaningful data essential for identifying weak signals or long-distance faults.

Unprovision

delete the OTDR scan results in the selected direction.

Step 8

Click Start Scan button to start OTDR scan.

The OTDR-SCAN-IN-PROGRESS-RX alarm is raised and displayed ion the Alarms tab of the Fault Monitoring menu.

Connection Verification for NCS 1010

Cisco IOS XR Release 24.3.1

You can now verify the connections between OLT-C line cards and passive modules of NCS 1010 devices from the Connection Verification list located in the right-panel of the Node Functional View.

You can use Connection Verification to quickly identify and troubleshoot connectivity issues.

Cisco Optical Site Manager allows you to verify connections between the OLT-C line card and the passive modules a NCS 1010 device, helping to prevent miscabling during node installation. This process involves generating a specific probe signal from the dedicated Connection Verification Tunable Laser (CV-TL) located at COM-RX-2, and then detecting the probe signal on:

  • the same OLT-C line card.

  • the passive modules (Mux/Demux panel or breakout panel) connected to the OLT-C line card.

  • a different OLT-C line card or passive module belonging to the same near end (NE) node.

  • an optical interface (router ports or transponder) connected to the line card.
