The QSFP28 LR4 transceiver is a 100 Gbit/s pluggable module for bi-directional serial optical data communications such as 100GBASE Ethernet. The transceiver operates with four parallel data streams of 25.78 Gbps in order to provide an aggregated signaling rate of 103.125 Gbps. The four lanes are launched with center wavelengths of 1295.56nm, 1300.05nm, 1304.58nm and 1309.14nm and multiplexed onto singlemode fiber. On the receive side, the four lanes of optical data streams are de-multiplexed by the transceiver and retimed.
The module is fully compliant with all QSFP28 related MSA’s described in SFF-8665 and Digital Diagnostic functions are available through an I2C interface. QSFP28-LR4 complies with IEEE 802.3 and 100Gbase-LR4.
