Omnidirectional blocks are grouped for efficient navigation, and the OXC view is always expanded horizontally for consistent data flow visualization.

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

A Node Functional View (NFV) is a visual representation that provides details of a network rack, including the node and its associated components.

Using NFV, you can:

  • includes components such as cards and chassis.

  • switch between different views.

  • explore detailed maps of physical connections.

  • interact 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.

Optical Channel Monitoring

Optical Channel Monitoring (OCM) is a technology used to monitor the performance and health of optical signals (wavelengths) running through fiber networks. It enables operators to gain real-time visibility into the optical spectrum without disrupting traffic.

OCM improves network visibility, enables proactive maintenance, and provides signal assurance. These enhancements reduce downtime and operational complexity in large optical transport networks.

Key features of OCM

The Optical Channel Monitoring capabilities in the NCS 1010 provide the following essential functions for managing and troubleshooting optical networks:

  • Real-Time Spectrum Monitoring: OCM scans the optical C-band and visualizes the power levels of individual optical channels. This feature helps detect signal degradation, identify channel presence or absence, and recognize spectral interference.

  • Integration with NCS 1010 ROADM: The OCM integrated with the ROADM helps validate wavelength routing, power levels, and OSNR (Optical Signal to Noise Ratio).

  • Graphical Spectrum View: Cisco Optical Site Manager provides a visual representation of the spectrum with channel peaks, helping easily spot anomalies.

The table describes the action icons available in the OCM tab.

OCM spectrum graph

The OCM spectrum graph displays the power spectral density (dBm per GHz) across the optical C-band in the RX or TX directions. This highlights the presence and consistency of carriers.

  • X-Axis (Frequency in THz): Represents optical frequencies that cover the C-band.

  • Y-Axis (Power Spectral Density): Displays signal power in dBm per GHz, indicating the strength of received signals at each frequency.

Figure 2. OCM spectrum graph

OCM spectrum graph color elements

The color coding in the OCM spectrum graph identifies the type of signal at each frequency:

Color

Elements

Description

Green

Carrier

Valid optical channel present at that frequency.

Grey

ASE

Amplified spontaneous emission that represents optical noise level.

Yellow

Missing Carrier

Expected channel missing or underpowered (useful for fault detection).

OCM utilization table

The OCM utilization table presents a frequency-slot grid showing how much of the optical spectrum is currently in use, with each cell representing a discrete frequency-time slot. This table helps network operators quickly assess spectrum occupancy and identify free or underutilized slots for provisioning.

Read and interpret the layout of the OCM table as described in these points:

  • Columns: The columns in the table represent discrete frequency slot positions, indexed using normalized values (e.g., 0.01250, 0.02500), and aligned with the C-band spectrum.

  • Rows: Each row shows a specific optical frequency in THz, arranged from higher to lower values.

The color coding in the OCM table shows different spectral components:

Table 7. OCM utilization table color coding

Description

Green

Carrier

A green cell shows an active optical signal in that frequency slot and indicates live data traffic or a provisioned channel.

Light Gray

ASE

Light gray cells represent amplified spontaneous emission, which is optical noise.

Yellow

Missing Carrier

A yellow cell means the expected channel is not detected. This result can indicate signal loss, misalignment, or a transponder issue.

Dark Gray

Out of Scope

A dark gray cell shows a frequency region outside the monitoring scope of your current configuration.

Optical Time Domain Reflectometer

An Optical Time Domain Reflectometer (OTDR) is a built-in fiber diagnostic tool that

  • sends light pulses through the optical fiber,

  • measures the reflected signals to detect faults, measure span loss,

  • and locates events such as fiber cuts or high reflections.

OTDR benefits

Cisco Optical Site Manager allows you to access the OTDR functionality of the underlying device in a unified manner, regardless of potential device differences.

The OTDR feature offers several advantages for fiber management:

  • Assess fiber quality during system installation before activating traffic.

  • Measure real-time loss and back reflection for the fiber pair connected to the TX and RX ports.

  • Monitor the fiber during live system operation.

  • Inspect the fiber following cable cut and repair events

  • Detect fiber degradation due to aging and environmental factors by automatically monitoring span loss and ORL thresholds.

From Release 26.1.1, OTDR scan is supported on NCS 2000, in addition to the NCS 1000.

Provision OTDR for optical degree

OTDR is automatically provisioned by default when you onboard a device that already has OTDR configured. Use this task only when OTDR is not provisioned.

Before you begin

If the OTDR is not auto-provisioned or was manually unprovisioned, you can enable it by creating an optical degree. See Manage Optical Degrees.

Procedure

Step 1

Click Node Functional View in the left panel.

Step 2

Right-click an optical degree in the map view and click Open.

Step 3

Expand the panel at the bottom of the page.

Step 4

Click the OTDR tab.

Step 5

Click +Provision OTDR to activate monitoring and troubleshooting functionality.

Review the OTDR measurement data after activation to ensure proper monitoring.

OTDR icons

The OTDR tab displays the optical trace for the selected degree and direction, helping you analyze signal quality, detect faults, and verify fiber link health.


Note

When performing an OTDR scan on Cisco optical nodes, it is expected system behavior for the OTDR trace to display a long tail of noise extending beyond the fiber end or the configured scan range; this does not indicate a malfunction. In Auto mode, the system detects the actual fiber end, though a noise tail may still appear beyond this point. In Multi-Region and Expert modes , the scan range is determined exclusively by the configured "capture start" and "capture end" points (in km), rather than the span length configuration; consequently, a noise tail may appear beyond the configured capture end point.

Check the Denoise check box available under the zoom icon, to remove the noise trace.

Connection verification

Cisco Optical Site Manager offers a connection verification process that checks the cabling between the OLT-C line card and passive modules in an NCS 1010 device, helping prevent miscabling during node installation.

The connection verification process generates a specific probe signal from the Connection Verification Tunable Laser (CV-TL) located at COM-RX-2. This probe signal is then detected on the following components:

  • The same OLT-C line card.

  • 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 transponders) connected to the line card.
