NBS-SIGLANE-MIB is an NBS optical-transport vendor MIB that manages "signaling lane" objects for multi-lane optical ports such as QSFP, CXP, and CFP transceivers used in high-speed optical/WDM transport equipment. It exposes port-to-lane mapping tables along with per-lane optical parameters including frequency/wavelength and, per its short description, optical power and status. It is a hardware-status monitoring MIB at the optics level: tracking per-lane wavelength/frequency assignment and (per vendor description) received/transmitted optical power and lane status, which lets operators detect a failing transceiver lane, wavelength drift, or a lane reporting a fault/loss-of-signal condition. As a WDM/multi-lane optics MIB it likely depends on standard interface indexing (ifIndex) to tie ports back to IF-MIB interfaces. It is typically deployed on NBS WDM/optical transport network elements using multi-lane optical modules (QSFP/CXP/CFP) in metro/long-haul optical networks. Network engineers evaluating or troubleshooting this functionality can download the NBS-SIGLANE-MIB file directly to load it into their MIB browser.

An administrator would poll the nbsSigLanePortTable (indexed by nbsSigLanePortIfIndex) to see how many lanes (nbsSigLanePortLanes) are provisioned on a multi-lane optical port, then drill into the nbsSigLaneLaneTable/nbsSigLaneLaneEntry for each nbsSigLaneLaneIndex to check nbsSigLaneLaneFrequency and nbsSigLaneLaneWavelengthX. A lane reporting an unexpected frequency/wavelength value or a lane missing from the table would indicate a mis-tuned or failed optical lane within the transceiver.
