40G QSFP+ LR4 10km LC DDM QSFP28 Optical Transceiver

Guanglian's OPTR-QT73L-C is a 4x10G hot-pluggable optical transceiver, enables the integration of 4 transmitters, 4 receivers, and an optical MUX/DeMUX with AAWG 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 four 10Gb/s CWDM channels. The transceiver is designed for applications based on the QSFP MSA, IEEE 802.3ba, and 40GBASE-LR4 requirements of up to 10km reach.
