The QSFP28 LR4 stands as a hot-pluggable, full-duplex optical module that aligns with the IEEE 802.3ba standard. Tailored for extended-range transmission in 100G Ethernet applications, it operates within the 1295nm to 1310nm wavelength range. Utilizing single-mode fiber jumpers, it achieves an impressive transmission distance of up to 10 kilometers.

This optical marvel, the 100G QSFP28 LR4 module, adeptly transforms four 25Gbps electrical signals into four LAN WDM optical signals, skillfully multiplexing them into a single channel for seamless transmission. At the receiving end, the module deftly demultiplexes the 100G optical input signal into four LAN WDM optical signals, subsequently converting them into four electrical output signals.

Huihongfiber upholds a commitment to manufacturing QSFP28 LR4 optical modules in strict adherence to industry standards, garnering recognition from a plethora of satisfied customers. These modules seamlessly integrate with an array of switch brands in the market, including Cisco, Juniper, Arista, Brocade, Dell, and others.
