BS EN 61290 5 2 is a part of an international multi series standard that discusses test methods for optical amplifiers. BS EN 61290 5 2 applies to optical fiber amplifiers (OFAs) using active fibers, containing rare earth dopants, presently commercially available. BS EN 61290 5 2 is about the electrical spectrum analyser measurement methods for OFA reflectance. It specifies related
