Gain Flattened Booster EDFA for DWDM Networks (EDFA-GB-R)

Data Sheet

The Optilab EDFA-GB-R is a line of Gain Flattening Erbium-Doped Fiber Amplifiers are designed for in-line amplification of DWDM networks.

Product Overview

The Optilab EDFA-GB-R is a line of Gain Flattening Erbium-Doped Fiber Amplifiers are 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. This gain variation can be as great as 6 dB in magnitude. The EDFA-GB-R is unique in its dual-stage amplification and internal Gain Flattening Filter (GFF) to compensate the erbium fiber gain variation. This design enables EDFA-GB-R to reduce the gain variation to ±0.5 dB over its full operating wavelength range, 1530 nm to 1560 nm. Depending on the input power level of each channel, the EDFA-GB-R is able to amplify up to 64 DWDM channels. Contact Optilab for more information.
