Dispersion Compensation Module

Dispersion Compensation Module

The Dispersion Compensation Module is a purely passive module for compensating differences of velocity of various DWDM wavelengths in optical transmission systems. The SPEED-DCM ís available for customized distances starting from 20 km up to 200 km. The dispersion compensation is designed for protocol transparent data rates between 10 Mbps and 40 Gbps. Thus up to 80 DWDM wavelengths (100 GHz grid) can be compensated on a fibre optic link. The SPEED-DCM covers one slot in a SPEED-CARRIER 4.5U or in a SPEED-CARRIER 1U housing. In addition a single-slot housing is available for integration of a SPEED-DCM module.
