Complete Connect offers a hot pluggable QSFP+ LX4 transceiver module. It has been designed for use in 40 Gigabit Ethernet links over both MMF and SMF with transmission distances of up to 150m on MMF (OM3) and 2km on SMF. The transmitter DFB array converts 4 inputs channels 10Gbps electrical data to 4 CWDM optical signals and multiplexes them into a single channel for 40Gbps optical transmission. The receiver optically de-multiplexes a 40Gbps input into 4 CWDM channels signals and converts them to 4 channels of output electrical data. The central wavelengths of the 4 CWDM channels are 1271nm, 1291nm, 1311nm and 1331nm as CWDM wavelength grid defined in ITU-T G694.2.

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

Lifetime Performance Warranty

We are very confident in the performance and reliability of our transceivers that we offer a lifetime performance warranty. This is combined with our outstanding service and support levels to ensure complete peace of mind.

Our programming & 3rd party brand compatibility

All our transceivers are coded with the correct EEPROM (electrically erasable programmable read-only memory) to match your manufacturers codes. Not all manufacturers require a code, only the ones that try to tie you into buying their optics at inflated prices. Complete Connect have a professional team who are able to engineer code and new firmware releases from manufacturers to ensure we offer up to date compatibility with all major OEM, switch, router and storage device vendors.
