High-Gain Erbium-Doped Fiber Amplifier (gEDFA)

Data Sheet

The Optilab gEDFA series of Erbium-Doped Fiber Amplifiers (EDFA) are reliable and cost-effective high-gain optical amplifiers for use in HFC, RFoG, PON and deep fiber applications.

Product Overview

The Optilab gEDFA series of Erbium-Doped Fiber Amplifiers (EDFA) are reliable and cost-effective high-gain optical amplifiers for use in HFC, RFoG, PON and deep fiber applications. The gEDFA provides gain of up to 50 dB while accepting a wide range of input power levels. By combining 980 nm/1480 nm pump laser modules and high efficiency Erbium-doped fiber, gEDFA amplifiers deliver output up to +24 dBm, while maintaining a low Noise Figure (NF). In conjunction with other Optilab transmitter products, the gEDFA can be used for transmitting forward 1550 nm analog channels and/or 100% QAM256 signals. Constructed with long term uninterrupted service in mind, the gEDFA provides the best cost/performance ratio in the industry. Contact Optilab for more information.
