This 100GBASE-SR4 optical transceiver module,has a Quad Small Form-Factor Pluggable 28 (QSFP28) form-factor and is of high performance in bi-directional signal transmission with an aggregate 100Gb/s bandwidth. The transceiver is designed to support Ethernet 100G-SR4/CAUI-4 and high-performance computing (HPC) InfiniBand EDR standards.

This QSFP28 100G SR4 transceiver offers 4 independent transmit and receive channels, and each is capable of 25Gb/s operation for an aggregate data rate of 100Gb/s on 100 meters of OM4 multi-mode fiber. An optical multi-mode fiber with an MTP/MPO connector can be plugged into the QSFP28 module receptacle.

Compared with conventional copper-based direct attach cables (DACs), optical fiber with pluggable MPO connectors simplifies complicated data center cabling deployment by its longer, lighter, and bendable characteristics. The optical transceiver utilizes high-performance 850nm GaAs VCSELs and PIN PDs with superior integration in signal integrity and optical sub-assembly, enabling a bit-error-rate of better than 10-15 for reliable packet communication within the data center.

Digital diagnostic functions are available via the I2C interface, as specified by the QSFP28 MSA . The optical transceiver is RoHS compliant as described in Application Note AN-2038.
