DCM dispersion compensation module – single-mode fiber C-band 100% slope compensation
The single-mode fiber C-band 100% slope compensation module (dispersion compensation module DCM) can perform wide-band dispersion and dispersion slope compensation for standard single-mode fiber (G.652) in the C-band, optimizing the system residual dispersion. This module is based on mature and reliable optical fiber technology and can improve the performance of optical transmission systems.
The dispersion value range of the dispersion compensation module at 1550nm wavelength can reach -10 to -2100ps/nm. Modules with special requirements for center wavelength and dispersion can also be provided.
