The 40G&100G Muxponder supports 4x10G 40G or 4x25G 100G electrical layer multiplexing/demultiplexing, and converts the multiplexed/demultiplexed optical signals into DWDM standard wavelength optical signals. ith DWDM MUX/DEMUX, multi-channel 100G or 40G services are transmitted in the DWDM system. 40G&100G Muxponder is the lowest cost solution for 100G metropolitan area network DWDM transmission. Support: 4x25G 100G/100G 4x25G Client side: 100G QSFP28 module Line side: 4xSFP28 module(Four 25G ports) Support one 100G service de-multiplexed into four 25G rate WDM standard wavelength optical signals Support port loopback test 40G&100G Transponder incorporates QSFP28-based access interfaces that can accommodate various types of QSFP28, e.g. Multimode Single mode, The 4SFP port is 4x 10Gbps /4x25G ,permitting flexible connectivity options between the muxponders either in a WDM system, Compared with the 100G coherent solution, the 40G&100G Transponder DWDM solution significantly reduces costs and is the most cost-effective metropolitan area network and big data center expansion solution. The TMUX8 fit HT6000 Series CH04, CH08, CH20 Chassis.
