Abstract

We review digital longitudinal monitoring, particularly longitudinal power monitoring (LPM), which estimates fiber-longitudinal optical power at a coherent receiver. We highlight key experiments including precise LPM closely matching OTDR and its feasibility demonstration at operational powers.
