C+L Band 26dBm 400mW Erbium-doped Fiber Amplifier

With the rapid development of information technology, optical fiber communication has become the cornerstone of modern communication networks. In optical fiber communication systems, erbium-doped fiber amplifiers (EDFA) play a vital role, and C+L Band 26dBm erbium-doped fiber amplifier is one of the best.

C+L Band 26dBm Erbium-doped Fiber Amplifier is a high-efficiency fiber amplifier that can achieve efficient signal amplification in the C+L band. Its high power output of 26dBm enables the signal to maintain a high signal-to-noise ratio and stability during transmission, effectively reducing signal attenuation and distortion, thus improving the overall performance of the optical fiber communication system.

This is a C+L Band 26dBm EDFA Amplifier. The wavelength Range is 1528~1563nm & 1570~1603nm. The EDFA supports two working modes, ACC and APC, and the two working modes can be switched. In APC mode, the output power can be adjusted. In ACC mode, the operating current can be adjusted. Our desktop EDFA can be controlled by buttons. PC control software can be connected through RS232 serial port.
