• Name: 40GBASE-LR4 and OTU3 10km QSFP+ Optical Transceiver
  • Views : 3016


Gigalight technology enables the integration of 4 transmitters, 4 receivers and an optical MUX/DeMUX into a small form factor package that delivers a 40 Gbps 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-LR transceiver is designed for applications based on the IEEE 802.3ba 40BASE-LR4 standard of up to 10km reach.
