PRODUCT DESCRIPTION
40GBASE-LR4 CFP module are a high performance, low power consumption, long reach(10km to 20km) , links over single mode fiber interconnect solution supporting 40G Ethernet and PCIe. It is compliant with the CFP MSA and IEEE P802.3ba 40GBASE-LR4. PrimusIT CFP LR4 modules offer 4 transmit and 4 receive asynchronous channels operating at up to 11.2Gbps per channel.
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.
Digital diagnostics functions are available via an MDIO interface, as specified by the CFP MSA. The transceiver is RoHS-6 compliant and lead-free per Directive 2002/95/EC3.
