DCM Dispersion Compensation Module
Optical Fibers
Fiberwdm
Dispersion Value [DCM module; 10KM]: typical:-318 ps/nm; max:-340 ps/nm Dispersion Value [DCM module; 20KM]: typical:-330 ps/nm; max:-346 ps/nm Dispersion Value [DCM module; 40KM]: typical:-670 ps/nm; max:-690 ps/nm
The single-mode-fiber C-band 100% slope-compensation module, or dispersion-compensation module (DCM), provides broadband dispersion and dispersion-slope compensation for standard single-mode fiber (G.652) across the C band, optimizing residual system dispersion. Mature, reliable fiber technology improves optical-transmission-system performance. Dispersion values at 1550nm range from -10 to -2100ps/nm. Modules with special center-wavelength or dispersion requirements are also available.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
