Cisco Dispersion Compensation Unit - transceiver

The DCU assembly provides compensation for accumulated chromatic dispersion effect in line and terminal sites of optical telecommunications systems. It provides a flexible solution to the problem of accumulated chromatic dispersion without having to drop and regenerate the wavelengths on the link, which would otherwise be necessary when accumulated chromatic dispersion exceeds the maximum allowed dispersion tolerance.

This DCU module provides 1150 ps/nm Compensation Level.
