Testing of Communication Optical Fiber Cable Specifications
The IEC has published a new standard for the testing of fibre optic cabling. 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. Lower attenuation means less signal loss over distance. Patch cords and jumper cables must meet stricter performance requirements because connectors introduce additional loss.
