Description

40G QSFP+ ER4 Lite TransceiverWestbury's QSFP+ module is designed to operate over single mode fibre using 4X10 CWDM channel in 1310nm band and links up to 30km. The module converts 4 inputs channel of 10Gb s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 40Gb s optical transmission. Reversely, on the receiver side, the module optically de multiplexes a 40Gb s input into 4 CWDM channels signals, and converts them to 4 channel output

Westbury's 100G QSFP28 series are IEEE 802
