What Do You Mean By Differential Fiber Distance?

Question

Accepted Answer

Differential fiber distance refers to the variation in length between two fiber optic cables.

It is the difference in length between two fiber optic cables.
It is important to consider the differential fiber distance when connecting fiber optic cables.
Differential fiber distance can cause signal loss or degradation if not properly accounted for.
For example, if one cable is 100 meters long and the other is 105 meters long, the differential fiber distance is 5 meters.

Accepted Answer

In GPON, the maximum differential fiber distance is 20 kms. This affects the size of the ranging window and provides compliance with [ITU-T G.983.1].
