Product Overview

The Optilab EDFA-GI series is a line of Gain-Flattening Erbium Doped Fiber Amplifiers designed for in-line amplification of DWDM networks. When a standard EDFA is used to amplify multi-channel DWDM signals, the output power level of various channels will vary according to the gain profile of the erbium fiber. The gain variation can be as great as 6dB in magnitude. The EDFA-GI has unique features of a dual-stage amplification and a internal Gain Flattening Filter (GFF) to compensate for the erbium fiber gain variation. This design enables EDFA-GI to reduce the gain variation to ±0.5dB over its full operating wavelength range from 1529nm to 1561nm. Depending on the input power level of each channel, EDFA-GI is able to amplify up to 64 DWDM channels.

The EDFA-GI is a versatile and powerful line of fiber amplifiers. The EDFA-GI series incorporates four pump sources, two 980nm lasers and two 1480nm lasers. With all four pump lasers set to maximum operating current, the total output power level of EDFA-GI can reach +24dBm (250mW). 

Housed inside a standard 1U rack mount case, the EDFA-GI has an easy to use control interface and clear LCD display. This product is constructed with 100% Telcordia qualified components to ensure 15 years of continuous operating life and is covered under Optilab’s three-year standard warranty. Optilab’s technical team provides full product support and application development consultation.
