Fixed Dispersion Compensation (DCM)
The DCM fixed dispersion compensation board was developed by Huixinte Communications to address fiber dispersion in high-speed, long-distance communication systems. It uses a new single-mode fiber for dispersion compensation of installed G.652&G.655 standard single-mode fibers. DCM provides dispersion-slope compensation over a broad C-band range for standard single-mode fiber (G.652), optimizing residual system dispersion. Based on mature, reliable fiber technology, it improves optical-transmission system performance. At 1550nm, the dispersion range reaches -10 to -2100ps/nm. Products with special center-wavelength and dispersion requirements are also available.
