EDFA DWDM model is designed and manufactured especially for applications in dense WDM optical networks. It provides high power, high gain and low noise amplification for 16, 32 and even 64 channels at wavelengths of C band.

Following three sub-types are provided under this class to meet the optical amplification requirement on different segment of DWDM networks.

Type 1: Inline amplifier - features medium input power, high output power, high optical gain and low noise figure. This type is designed for optical amplification between two network nodes on the main optical link and handles all optical channels.

Type 2: Booster amplifier - features high input power, high output power, medium optical gain. This type is design for amplification of high overall input optical power.

Type 3: Two stage amplifier - features with medium input power, high output power, high optical gain and middle stage design. Up to 11dB loss can be tolerated in the middle stage, which enables the use of DCM (dispersion compensation module), optical filters, add/drop modules, etc. in the middle stage.

Features:

• Excellent gain flatness
