Description

Link-all's LAQS-LR4 is a QSFP+ transceiver module designed for 10 km optical communication applications with single mode fiber. It is compliant with IEEE 802.3-2018 40GBASE-LR4, IEEE 802.3-2018 Annex 86A, QSFP+  MSA standards.  Digital  diagnostic  management  interface  (DDMI)  is  realized  by  I2C  interface  in
compliance with SFF-8636. The module is RoHS 2 compliant.
This module can convert 4-channel 10 Gbps electrical data to 4-channel optical signals, and mul-tiplex them into a single channel for 40 Gbps optical transmission. Similarly, it optically de-multiplexes a 40 Gbps input into 4-channel signals, and converts them to 4-channel output electrical data on the receiver side. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
