Optical fiber testing is divided into primary testing and secondary testing. The primary testing is also the basic testing. It mainly tests the insertion loss (that is, attenuation) of the optical fiber and the length of the optical fiber link. No matter it is single-mode fiber or multi-mode fiber, they are all made of glass fiber, and natural loss will inevitably occur when optical pulse sig...
