This document examines the requirements to enable accurate measurement of fibre optic links from start of life and during the life cycle of the system from installation and through-service. This document explains the issues associated with optical link measurement and provides techniques to address these issues. This document discusses the measurement of key parameters associated with the passive layer (i.e. transmission of light through an optical harness). This document does not discuss systems tests, e.g. bit error rates.
