Fiber Optic Technician Interview Questions and Answers

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.

The maximum logical reach in GPON is typically 20 kilometers.

• GPON stands for Gigabit Passive Optical Network.

• The maximum logical reach refers to the maximum distance that data can travel over a GPON network.

• The typical maximum logical reach in GPON is 20 kilometers.

• This means that data can be transmitted up to 20 kilometers from the central office to the end user.

• Beyond this distance, signal degradation may occur and additional equipment may be required to extend the reach.
