The Tellabs 81.7100DCM-BLK is a dispersion compensation module (DCM) designed for Tellabs / Coriant optical transport systems. It is used to correct chromatic dispersion in fiber optic networks, ensuring signal integrity over long-distance transmission.
Chromatic dispersion can degrade optical signals in high-speed networks, and this module compensates for that effect, improving performance and extending transmission reach in DWDM systems. It is a critical component in long-haul and metro optical networks.
