Understand OTDR module capabilities, cabling, configuration modes, event-based automatic scans, scan status and output, photodiode power levels, IPv6 support, and machine learning event classification on Cisco NCS 1001 systems.
OTDR
This topic describes the OTDR line card, its physical and logical ports, supported measurement modes, and operating limits for Cisco NCS 1001 fiber inspection.
Cable a terminal node for OTDR
Use this procedure to connect OTDR and EDFA ports in a terminal node so that OSC and OTDR signals are carried through the expected fiber path.
Cable an ILA node for OTDR
Use this procedure to connect a single OTDR card to the EDFA cards in an ILA node so both ILA directions support OTDR measurements.
Cable an ILA node with 15216-FLD-OSC for OTDR
Use this procedure to connect ILA cabling through the 15216-FLD-OSC module when the deployment still uses that module in the OSC path.
Clear the card configurations
Use this procedure to clear card-level, OTS controller, and optics controller configurations before you replace a configured optical module with an OTDR module.
Configure OTDR
Use this procedure to configure OTDR optical parameters for TX and RX directions after the OTDR card is inserted into Cisco NCS 1001.
Configure OTDR in automatic mode
Use this procedure to configure automatic mode OTDR parameters so the device can run training and measurement phases with default or customized scan values.
OTDR measurement in automatic mode based on events
This topic explains which events start OTDR automatic scans and how the supported deployment scenarios determine the autoscan configuration for node pairs.
TCP/IP ACLs for span loss and OTDR autoscan traffic
This section explains how optional TCP/IP access control lists (ACLs) restrict span loss calculation and OTDR autoscan traffic between Cisco NCS 1001 nodes.
Configure OTDR in expert mode
Use this procedure to configure expert mode OTDR scan parameters when automatic adjustment is not used for the selected port and direction.
Stop OTDR measurement
Use this procedure to stop an OTDR measurement that is running in automatic or expert mode and verify that the scan is stopped.
Display OTDR photodiode power levels
Use this procedure to display photodiode power values and the logical ports associated with the OTDR module physical ports during controller verification.
OTDR machine learning events
This topic provides reference details for OTDR machine learning feature history and event classifications shown in scan output when machine learning is enabled.
