Optical power
Testing for loss requires measuring the optical power lost in a cable (including connectors, splices, etc) with a fibre optic source and power meter by mating the cable being tested to known good reference

Insertion loss testing checks how much signal is lost as light travels through the fiber link. The IEC 61300-3-4 standard recommends the one-cord reference method for best accuracy. Fiber optic loss testing is an essential part of maintaining reliable, high-performance fiber optic networks because it helps identify potential issues and ensures that the system meets the required performance specifications. To use a power meter for fiber optic testing, always clean connectors first with lint-free wipes or click-to-clean tools. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power.
