WHAT IS THE INSERTION LOSS AND RETURN LOSS OF COMPONENTS IN OPTICAL FIBER CABLE?

In fiber optic communications, insertion loss and return loss are two important indicators for evaluating the quality of fiber optic cable assemblies. Such as fiber optic connectors, optical jumper fibers, and pigtails. So what is the fiber cable insertion loss? So what is the optical fiber cable return loss? What is the insertion loss of fiber op

Optical fiber generally divided into three layers: core, cladding and coating. The core and cladding composed of glass with different refractive indices. The fiber core is a glass with a high refractive index (silicon dioxide doped with germanium). And the fiber cladding is a silica glass with a low refractive index (pure silica). Light enters the
