Description

The ET6401-LR4 QSFP+ transceiver is designed for 40 Gb/s links over single mode ﬁber. The transceiver integrates

a four-channel CWDM DFB laser and multiplexes them into a single channel for 40 Gb/s optical transmission; in

receiver side, the module de-multiplexes the 40 Gb/s optical signal into four CWDM channels. Each channel

operates at 10.3125 Gb/s, and the module can operate at 40 Gb/s up to 10 km using 9/125 um SMF. The transceiver

is compliant with the QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4.
