Erbium-doped Fiber Amplifiers (EDFA)

Download Datasheet

An erbium doped fiber amplifier is a type of optical amplifier that amplifies an optical signal directly, without the need to first convert it to an electrical signal. A complete line of EDFA gain modules are available, designed to meet various amplification requirements for single-channel, narrow-band, and DWDM transmission in metro, long-haul and ultra-long-haul networks as well as test & measurement applications.

BaySpec supplies IntelliGain® series metro erbium-doped fiber amplifiers (EDFAs) designed for OEM integration into applications that require a high gain and a low noise figure. The IntelliGain® Metro_AE modules feature low power consumption, high efficiency and compact mechanical package. The driving and controlling electronics are fully integrated into the 120×95×13 mm3 package. The amplifiers have a typical noise figure of <5.0 dB across the entire 1530 nm to 1562 nm wavelength range and meet Bellcore GR-1312-Core requirements.
