40gbase Qsfp Lr4 Fiber Optical Transceiver Module 10km On Smf Lc Connector
Overview
40G QSFP LR4 is The sourcelight technology enables the integration
of 4 transmitters, 4 receivers and an optical MUX/DeMUX into a
small form factor package.
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.
The QSFP-LR transceiver is designed for applications based on the
IEEE 802.3ba 40BASE-LR4 standard of up to 10km reach.
