Product Info
Introduction
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.
The module integrates both an Erbium Doped Fiber Amplifier (EDFA) and a Raman amplifier inside the module, which significantly reduces system complexity, improves reliability, and reduces size compared to traditional EDFA and Raman amplification systems. It is suitable for distributed fiber optic sensing systems to amplify weak optical signals to achieve longer detection distances.
