CFP4 LR4 Optical Transceiver with 100GE for up to 10 km Reach
JC4 Series, TRA5E20ENF-LF000 Series, TRA5E20FNF-LF000 Series
The Lumentum 100G CFP4 LR4 optical transceiver is a full duplex, photonic-integrated optic transceiver that provides a high-speed link with an aggregated data rate of either 103.125 Gbps or 111.81 Gbps over up to 10 km of SMF28. The module complies with the CFP MSA CFP4 Hardware Specification Rev. 1.0, IEEE802.3-2012 Clause 88, IEEE 802.3bm CAUI-4 chip to module electrical standard and ITU-T G.959.1-2012-02.
The transceiver integrates the receive and transmit paths on one module. On the transmit side, four lanes of serial data streams are recovered, retimed, and passed to four laser drivers. The laser drivers control four electric-absorption modulated lasers (EMLs) with center wavelengths of 1296 nm, 1300 nm, 1305 nm and 1309 nm. The optical signals are multiplexed to a single-mode fiber through an industry standard LC connector. On the receive side, the four lanes of optical data streams are optically de-multiplexed by the integrated optical demultiplexer. Each data steam is recovered by a PIN photodetector and transimpedance amplifier, retimed and passed to an output driver. This module features a hot-pluggable electrical interface, low power consumption, and an MDIO management interface.
