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 Solução de retransmissão de sistemas modernos de comunicação óptica, suporta a transmissão de alta capacidade de linhas de tronco de longa distância, cabos ópticos submarinos e redes multiplexador de divisão de comprimento de onda (DWDM), promovendo a evolução das redes totalmente ópticas e arquiteturas 5G Frhhaul .}
