OTN6500 10G/25G SFP+ SFP28 CWDM DWDM OTN Transponder

What is OTU Transponder?Transponders are used to enable point-to-point connections over long distances when the client rate matches the optical wavelength. In cases where the client rates are lower than the optical wavelength.What is Muxponder?A muxponder is the element that sends and receives the optical signal on a fiber in much the same way as a transponder except that the muxponder has the additional functionality of multiplexing multiple sub-rate client interfaces onto the line interface.Main difference between Transponder vs MuxponderTransponderN in N out: N* Low-speed client-side services==> N* Standard wavelength optical signalsMuxponderN in One out: N* Low-speed client-side services ==> 1* High-speed standard wavelength optical signal 10G SFP+ CWDM DWDM Transponder Functional Structure   10G/25G SFP+/SFP28 Transponder Specifications Parameter Technical  Card type 10G OTU-3R 25G OTU-3R interface Client-side interface: 4 or 5 SFP+ hot-pluggable, compatible with SF
