Fiber jumper wire of web-class and telecom carrier class

Optical fiber jumper wire is divided into three types: telecom type, web-class type and broadcasting type. The insert loss (RL) of telecom optical fiber jumper wire should be less than 0.3dB while all the RL less than 3dB can be used in web-class optical fiber jumper wire.

The requirement of web-class is lower, but the attenuation of web-class is larger than telecom type.
