DCM Dispersion Compensation Equipment
Product Overview
Fholink's DCM Dispersion Compensation Module is designed to provide broadband dispersion and dispersion slope compensation for standard single-mode fiber (G.652) in the C-band, optimizing the residual dispersion of the system. Based on mature and reliable fiber technology, this module enhances the performance of optical transmission systems.
The dispersion compensation module offers a dispersion value range of -10 to -2100 ps/nm at the 1550nm wavelength. Custom modules with specific requirements for center wavelength and dispersion are also available.
Features
1. Broadband dispersion compensation for DWDM systems with extremely low residual dispersion
2. 100% slope compensation (standard value) for G.652 fiber in the C-band
3. Low insertion loss
4. Low polarization mode dispersion
5. Available in various packaging styles, connector types, and jumper lengths
