Complete Connects QSFP+ eSR4 transceiver module is designed for use in 40Gbps links over multimode fibre. The transmitter converts parallel electrical input signals into parallel optical signals. These input signals are compatible with Common Mode Logic (CML) levels which are deferentially and internally terminated. The receiver converts parallel optical input signals via a photo detector array into parallel electrical output signals. These outputs electrical signals are voltage compatible with Common Mode Logic (CML) levels, differential and support a data rates up to 10.3 Gbps per channel.

Digital diagnostics functions are available via an I2C interface, as specified by the QSFP+ MSA. The transceiver is RoHS compliant and lead free.
