40gbase - lr4 SMF QSFP Optical Module 1310nm 10km For QSFP-40G-Lr4 Data Center
Overview
40G QSFP LR4 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.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.
