Dispersion Compensation Module

F-DCM Dispersion Compensation Module

For extremely long fiber transport distances of greater than 80 km, fiber-optic dispersion compensation modules are often required. These are passive devices intended for signals in the 1550 nm range. Because of the insertion loss, it is often necessary to use these modules with an Erbium-Doped Fiber Amplifier (EDFA) before the signal enters the DCM. When used properly, this equipment can enable fiber-optic transport of signals beyond 200 km.
