Home / Methods for measuring fiber optic channel links
IEC 61280-4-5 provides test methods to measure the attenuation of installed multimode and single-mode optical fibre cabling plant as well as the determination of their polarity and length. This Applications Engineering Note (AEN 135) explains and recommends standard measurement methods for characterizing optical fiber system performance. These test procedures assess the physical and functional qualities of fiber optic cables, connectors, and the network as a whole.
