HTF’ s QSFP+ 40G 40KM is a parallel 40Gb/s Quad Small Form-factor Pluggable (QSFP+) optical module and designed for 30km optical communication applications. The module converts 4 inputs channels (ch) of 10Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb/s optical transmission. Reversely, on the receiver side, the module optically de-multiplexes a 40Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data.
