What is otdrPortOtdrIor?

This read-only value reports the group index of refraction (IOR) configured for the fiber being measured by the OTDR on this port, defaulting to auto. The IOR value is what the OTDR uses internally to convert the light's round-trip travel time into a distance-to-event measurement, so an incorrect IOR would make the reported distance to a break or splice wrong. For example, if the actual fiber's IOR differs from the configured value, a real break at 42 km could be reported at a slightly different distance until the IOR is corrected.

Examples
