  • Our DWDM MUX and DEMUX are integrated in one device, the single fiber DWDM MUX/DEMUX line port is simplex, and the signal input and output are transmitted through the same port; In addition, the EDFA is directional, red and blue filters are required to separate and amplify the signals in two different directions. After amplification, the red and blue filters are used to combine the wavelengths in both directions with the single-core optical cable/DWDM MUX simplex line port Connection transmission.By L***d on 06/07/2020
