Miray’s 40GE QSFP+ ER4 40km Optical Transceiver modules are designed for using in 40 Gigabit Ethernet and 4X10G OTN client interfaces over single mode fiber. They are compliant with the QSFP+ MSA, IEEE 802.3bm 40GBASE-ER4, and OTU3 requirements. The Gigalight technology enables the integration of 4 transmitters, 4 receivers and an optical MUX/DeMUX into a small form factor package.
