Enhanced DAS all-in-one is capable of real-time demodulation of the phase of the entire fiber optic cable, TCP protocol output of vibration signals, and coherent attenuation suppression, enabling the output of purer signals than general-purpose DAS all-in-one.

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.
