The HL-QSFP-40G-LR4 is a high-performance transceiver module designed for 10km optical communication applications. Compliant with 40GBASE-LR4 of the IEEE P802.3ba standard, this module converts 4 input channels of 10Gb/s electrical data to 4 CWDM optical signals, multiplexing them into a single channel for 40Gb/s optical transmission. On the receiver side, it optically de-multiplexes a 40Gb/s input into 4 CWDM channel signals and converts them to 4 channel output electrical data.
