4 Ports Fiber Optic WDM EDFA

1550nm high-power fiber amplifier adopts two-stage amplification, the first stage adopts low-noise EDFA, the second stage adopts high-power EYDFA, the total output optical power can reach 40dBm. It can replace several or dozens of EDFA, which can greatly reduce the cost of network building and maintenance and reduce the space of head-end . Each output port is built in with CWDM to multiplex CATV signal and OLT PON Data flow. The device will play an increasingly important role in the process of continuous extension and expansion of optical fiber network. It provides a high stability but low cost solution for the triple-play and large area coverage of FTTH.
