80KM Passive Dispersion Compensation Pluggable Module
Dispersion Compensation Module (DCM) is designed to fix the form of optical signals that are deformed by chromatic dispersion. The main constituent of DCM is DCF (Dispersion Compensation Fiber) with a negative chromatic dispersion value within the wavelength range between 1525nm and 1565nm. The module offers a high level of compensation while maintaining a low flat insertion loss as well as a low latency. When combined with EDFA and OEO, DCM provides a simple, reliable, and cost-effective long-haul transport solution, making signals go further without regeneration.

Product Highlights
Explore the New Generation of Our FMT Series
Pure Passive Dispersion Compensation Module for C-band DWDM System
- Individual compensation levels & Protocol transparent (10 Mbps to 40 Gbps) & Compact design
- Low polarization mode & Wide band dispersion compensation & 100% slope compensation
- DCM with high performance provides the perfect opportunity to build SDH/SONET, CATV and DWDM system
DCF-based Module Pushes Limits of Transmission Distance
The pure passive DCM guarantees the normal working after the power failure, supporting high reliability. The excellent DCF (Dispersion Compensation Fiber) can properly correct or reverse the dispersion that was realized as the signal traversed the optical fiber, ensuring long-haul transmission.
Pre-, Post-, and Symmetrical-compensation by Using DCM
Pre-compensationPlacing between MUX and BA which provides dispersion compensation before the optical signal of the multiplexing segment entering the transmission line.
Symmetrical-compensationPlacing ahead of LA or between PA and BA which can compensate the optical fiber before each amplifier station.
Post-compensationPlacing ahead of PA or between PA and BA which can compensate the transmission fiber of the last amplification segment in the multiplexing segment.
Available for All-in-One Multi-Service Transport System
As a part of multi-service transport system, a hot-swappable pluggable DCM card occupies 2 slots in the 1U/2U/4U chassis, which can be highly integrated with FS management platforms and OEO/EDFA/OLP products.

Hybrid DWDM over CWDM Network
CWDM wavelengths range from 1260-1625nm, channel spacing is 20nm, which actually cover all the range of DWDM wavelengths (1470-1625nm). And DWDM wavelengths have much smaller channel spaces (0.4nm/0.8nm). Therefore, the CWDM wavelengths near DWDM wavelengths can be used to transmit the DWDM wavelengths.
