DCM
DCM dispersion compensation module is passive dispersion management elements that can be inserted into an optical fiber network to control the overall chromatic dispersion. It provides negative dispersion for dense wavelength division multiplexing (DWDM) transmission systems. They can be used to compensate dispersion on standard single-mode G.652 (NDSF) optical fiber (SMF) across the entire C band.
Product Features
l 100% slope compensation of G.652 optical fiber in C-band
l Low insertion loss
l Low polarization mode dispersion
l Wide band Dispersion Compensation for DWDM System
Product Applications
l SDH high speed optical transmission system
l DWDM optical transmission system
l G.652 Standard single-mode optical fiber long-distance and metropolitan area communication system
