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.
Optelian's FBG-based DCM's have low insertion loss, exceptional linearity and low latency. They can be placed anywhere including pre, post or mid stage applications.
The following table shows the Optelian amplifer and DCM modules to use based application requirements.
Optical FiberAmplifiers (OFAs) provide the reach needed for long-haul DWDM, ROADM, and higher-loss metro OADM applications.
Optelian's OFAs are gain-flattened, low-noise, C-Band Erbium-doped fiber amplifiers (EDFAs). They can be used in post-amp (booster), line-amp, or pre-amp configurations.
They have output power as high as +20 dBm and power consumption as low as 9.5 watts. Their small size, each at 1 slot wide, makes them easy to fit into crowded racks and remote terminals.
