The OT-DCM-F Series Fiber-Based Dispersion Compensation
Module removes distortion from optical signals that have traveled
long distances over standard, positive dispersion, SMF-28 fiber. In
digital systems, this dispersion limits the maximum transmission
distance at a given data rate and causes increased BER. In analog
systems, this dispersion manifests itself as second order distortion
in the signal. The OT-DCM-F Dispersion Compensation Module
cancels out the fiber’s positive dispersion, increasing transmission
distance and enhancing the fidelity of all types of optical signals.

Applications

• Increase Distance and Decrease
BER of Digital Fiber Optic Links

• Reduce Distortion in Analog Fiber
Optic Links

• No Need for Precisely Tuned
Channel Wavelengths

• Works with Both Analog and Digital
Signal Formats

Note: Each DCM module is designed to compensate for a specific amount of dispersion. For example, the OT-DCM-F10 is

designed to compensate for 10 km of G.652 fiber dispersion, and the OT-DCM-F100 is designed to compensate for
100 km of G.652 fiber dispersion. 'The units can be ordered in 10km increments.
