Description
The CFP optical transceiver module are a high performance, low power consumption, long reach(10 km) interconnect solution supporting 40G Ethernet. It is compliant with the CFP MSA and IEEE P802.3ba 40GBASE-LR4. F-tone CFP 40G LR4 modules offer 4 CWDM transmit and 4 CWDM receive asynchronous channels operating at up to 11.2Gbps per channel.
As shown in Figure 1, the transmitter side of the module consists of an array of VCSELs (Vertical Cavity Surface Emitting Lasers) and associated circuitry, which converts 4 parallel electrical data inputs to 4 parallel optical data output signals and also converts 4 parallel optical signals into 4 parallel electrical signals through an array of PIN photodiodes and associated circuitry.
