This 1531nm high-power single-mode erbium-doped fiber amplifier (EYDFA-HP) operates based on the principle of stimulated emission amplification in rare-earth-doped optical fibers.

With an optimized optical path structure and reliable laser thermal management, it delivers stable and high-power laser output centered at 1531nm, featuring high output power, low noise, high gain, and outstanding cost performance. It supports an input power range of +6 to +20 dBm and provides a saturated output power of 30 dBm at 10 dBm input, with output power adjustable from 10% to 100%. The module shows excellent optical performance with a noise figure below 6.0 dB, gain unevenness ≤ 1 dB, polarization-dependent gain ≤ 0.5 dB, and input/output isolation ≥ 35 dB.

It supports ACC/APC/AGC operating modes and integrates real-time input and output optical power monitoring. Adopting SMF-28 single-mode fiber with FC/APC connectors, it ensures stable transmission and convenient integration. Equipped with a DB9 female RS232 communication interface and powered by DC 12V (<36W), this amplifier is designed for long-term reliable operation in environments from -5°C to +55°C.

It is widely used in fiber-optic communication, fiber sensing, fiber laser systems, lidar, and other high-performance optical applications.
