Explains how connection verification uses a dedicated tone to validate cabling between the Optical Line Terminal line card and NCS1K-CCMD-16 line cards during node installation.


A connection verification method is a cabling validation process that

  • checks the connection between the Optical Line Terminal (OLT) line card and NCS1K-CCMD-16 line cards,
  • prevents miscabling during node installation, and
  • uses a dedicated probe signal to verify connectivity.

Connection verification signal

You can use verification tasks to validate the connection between the Cisco NCS 1010 OLT line card and the NCS1K-CCMD-16 line card during installation. The dedicated Connection Verification Tunable Laser (CV-TL) on the OLT card generates a probe signal at a specific frequency and power, which the connected CCMD-16 line card detects. This process ensures that connections are correct and helps avoid errors in cabling.

For comprehensive details about the connection verification process, refer toCisco NCS 1010 Datapath Configuration Guide.


Power data readings

Use this reference to identify the photodiode monitors, calibrated ports, port labels, and power ranges used in connection verification.

Photodiodes (PDs) are optical power monitors available on all input ports and aggregated output ports. Tone detection is enabled on some PD monitors.
