40G QSFP ER4 is a 4x10G hot pluggable optical transceiver. The Sourcelight Technology enables the integration of 4 transmitters, 4 receivers and an optical MUX/DeMUX into a small form factor package that delivers a 40Gbps data link in a compact QSFP footprint.

The optical connectivity is based on two SMF LC connectors, one for Tx and one for Rx. The Tx and Rx each consist of 4 10GB/s CWDM channels, whose wavelengths are in the 1300nm range. The QSFP-ER transceiver is designed for applications based on the IEEE 802.3ba 40BASE-ER4 standard of up to 40km reach.
