Description
The CFP2 optical transceiver module are a high performance, low power consumption, short reach interconnect solution supporting 100G Ethernet and Telecom. It is compliant with the CFP2 MSA and IEEE P802.3ba 100GBASE-SR10. F-tone Networks CFP2 SR10 modules offer 10 transmit and 10 receive asynchronous channels operating at up to 11.18Gbps 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 10 parallel electrical data inputs to 10 parallel optical data output signals and also converts 10 parallel optical signals into 10 parallel electrical signals through an array of PIN photodiodes and associated circuitry. The refclk clock of 161.1328M for 100GE(or 174.6875M for OTU4) is necessary for our module.
