Overview
This chapter details how to regulate optical power on Cisco NCS 1010 to ensure signal quality and compensate for network degradation. It provides procedures for configuring power spectral density profiles and monitoring system states using centralized or decentralized span-mode operations across C and L bands.
| Feature Name | Release Information | Feature Description |
|---|---|---|
| APC enhancements |
Cisco IOS XR Release 7.9.1 |
APC (Automatic Power Control) on NCS 1010 now supports C+L band networks in addition to C band only networks. Also, APC is enhanced to perform power correction even when it doesn’t have end-to-end network visibility. This ensures that the operational section of the network always has power at the target PSD profile, and when the network comes up, the traffic restoration is faster. |
| Span-mode APC |
Cisco IOS XR Release 7.11.1 |
Span-mode APC is a decentralized approach to APC.Span-mode APC Span-mode APC allows for faster network convergence as power correction is performed independently for each span. |
Automatic Power Control
This topic explains automatic power control (APC), a network-level feature that regulates and maintains optimal optical power levels across multiple nodes to ensure consistent performance and compensate for network degradation over time. It outlines how APC operates, its functions, and its configurable parameters.
Operation of span-mode APC
This topic explains how span-mode APC operates in optical networks, detailing its decentralized automatic power control mechanism, key operational behaviors, and restrictions compared to centralized APC. It also covers relevant alarm conditions and configuration guidelines for effective deployment.
Switch between APC modes
Use this procedure to switch between centralized and span modes of APC on network nodes. This helps to reconfigure APC operation when you update network topology or operational requirements.
