DCF Overview

Apollo offers two types of DCF cards to properlycompensate for chromatic dispersion:

DCF652_xx DCF655_xx

To select the optimal solution for specific installations,several cards are available that differ in theircompensation capabilities

DCF cards are uni-directional

DCF652_xx is a Dispersion Compensating Fiber (DCF)card suitable for G. 652 compliant fibers

The card is available for compensation for variousdistances (5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100,

110, or 120 km)

The marking xx in the name of the card indicates the

distance in km
