Amplified DWDM systems experience accumulated delay induced by chromatic dispersion on long fiber spans. Dispersion Compensation Modules (DCMs) are used to control this delay. Chromatic dispersion is predictable and stable and can be compensated for using dispersion compensation modules. A single-slot DCM module is simply added to the system as needed.
eWAVE DCM's have low insertion loss, exceptional linearity and low latency. They can be placed anywhere including pre, post or mid stage applications.
