Gain Flattened Inline EDFA with Mid-stage Access (EDFA-GM-R)

Data Sheet

Product Overview

The Optilab EDFA-GM-R is a line of gain-flattening EDFA designed for optical amplification in DWDM networks. The EDFA-GM-R is typically used as an intermediate point in the network to increase the DWDM channel power levels, with the ability to amplify input signals as low as -18 dBm per channel. Featuring a dual-stage design with mid-stage access, the EDFA-GM-R can be fitted with Dispersion Compensation Modules (DCM) to reduce distortion due to effects of chromatic dispersion that occurs in single-mode fiber (SMF). The mid-stage access can also be used for installing Optical Add/Drop Module (OADM). The EDFA-GM-R provides flattened optical gain and low noise figures for optimum DWDM signal amplification. Various output power levels are available (ranging from +18 to +24 dBm) to provide maximum flexibility for network design and implementation. The Optilab EDFA and Raman amplifiers can provide an optimal solution for DWDM network optical amplification based on channel and transmission distance requirements. The EDFA-GM-R can be used in conjunction with Optilab EDFA-GB-R Booster EDFAs and RA-R Raman amplifiers to significantly increase the transmission distance and quality of DWDM signals. All Optilab DWDM EDFA products are constructed with 100% Telcordia qualified components to ensure 15 years of continuous operating life.
