Hilink 100G LR4 QSFP28 optical transceivers (HL-QSFP28-4LR4C) are designed for use in 100-Gigabit Ethernet links up to 10km on Single Mode Fiber (SMF).

Product description

This product is a 100Gb/s transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE P802.3ba standard. 

The module converts 4 input channels of 25Gb/s or 27.9GB/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes them into a single channel

for 100Gb/s optical transmission

Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of LAN WDM optical signals and then converts them to 4 output channels of

electrical data.The central wavelengths of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm 

Features:

Duplex LC receptacle optical interface

Single +3.3V power supply
