Testing Fiber Optic Cable
An understanding fiber optic cabling of fiber optic cable testing requires more background information than can be included in this book. This section provides a brief discussion of a few of the factors that are involved in testing fiber optic cable.
First of all, there is one boon. Crosstalk, a worrisome problem for twisted-pair media, does not occur for fiber optic media.
Some of the items that must be tested for fiber optic media include:
Source optical power— If the source power is inadequate, information transfer could be error prone or could fail.
Signal attenuation— Most attenuation is caused by scattering of light due to bouncing off the cladding or bouncing off atoms in the glass. Some attenuation is ...
