DCM
Dispersion Compensation Card

Name: DCM
Brand: Shenzhen C-Data Technology Co., Ltd.

DCM board is DCF-based passive dispersion compensation module, which compensates the dispersion slope of standard G.652 single-mode fiber in the C-band, ensures the signal quality of high-speed signal after long-haul transmission, eliminates intersymbol interference, mproves the transmission performance of the system, and realizes the transmission of long-haul,high-bandwidth and large-capacity signals.

The dispersion range of 1550nm wavelength can reach -2100 to -10ps/nm, and can provide products with special requirements for center wavelength and dispersion. When combined with EDFA. it provides a simple, reliable, cost-effective long-haul transmission solution for optical transmission, which makes the signal transmit further without regeneration.
