Description

DCM Dispersion Compensator has the capability of slope compensation which can supply the broad-band dispersion slope compensation for SMF-28 fiber (G.652) in whole C-band to optimize the system residual dispersion. With the mature and reliable optical fiber processing, the performance of optical transmission system can be sharply improved.
The dispersion range of 1550nm wavelength can achieve -10 ~ -2100ps/nm. Special requirements in central wavelength and dispersion can be provided.
