EDFA Fiber Amplifier Modules

Erbium-doped fiber amplifiers for boosting sensing pulse energy and extending measurement range in DTS, DAS, and optical test link applications.

Small signal EDFA erbium-doped fiber amplifier is used to amplify weak light signals or as a preamplifier for weak light detection, and is widely used in fiber optic sensing systems and fiber optic communication network systems.
EDFA-S Small signal erbium-doped fiber amplifier EDFA pre-amplification C-band
Pulsed EDFA erbium-doped fiber amplifier, C-band, commonly used after the acousto-optic modulator to achieve the amplification of pulsed optical signals, common in distributed fiber optic sensing systems, LIDAR and other applications.
EDFA-P Pulsed EDFA Erbium-doped fiber amplifier Pulsed signal amplification C-band
The module integrates both an EDFA erbium-doped fiber amplifier and a Raman fiber amplifier inside the module, which significantly reduces system complexity, increases reliability, and reduces size compared to conventional EDFA and Raman amplification systems. The front-end EDFA is available as a pulsed EDFA or an amplified EDFA suitable for ultra-long-range fiber optic sensing systems or high-speed fiber optic communication systems.
