Edfa

Erbium-doped fiber amplifier (EDFA) is a key device to achieve direct amplification of optical signals through erbium-doped fibers and pump lasers, which can provide high-gain, low-noise amplification in the 1550nm band (the lowest loss window of optical fibers) without photoelectric conversion, significantly extending the communication distance and reducing the cost of relay. As the Core Relay Solution of Modern Optical Communication Systems, den stöder överföring av hög kapacitet av långdistansstammlinjer, ubåtoptiska kablar och tät våglängdsavdelning (DWDM) nätverk, samtidigt som man främjar utvecklingen av alla optiska nätverk och 5G Fronthaul Architectures .}}}}
