Test methods for reflectance parameters - Electrical spectrum analyser method included-in-kit NOTE: BS EN 10293 doesWhat is BS EN 61290 5 2 Electrical spectrum analyser method about? 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
