PRODUCT PRESENTATION

The JFOPT QSFP28 100G LAN-WDM 10km LR4 LC DX Transceiver is a high-performance optical module designed for 100GBASE-LR4 applications, compliant with the IEEE P802.3ba standard. This module converts four channels of 25Gb/s electrical data into four LAN-WDM optical signals, multiplexing them into a single channel for 100Gb/s optical transmission. On the receiver side, it de-multiplexes a 100Gb/s optical input into four LAN-WDM channels and converts them back into four electrical output channels.The central wavelengths of the four LAN-WDM channels are 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm, aligned with the LAN-WDM wavelength grid defined in IEEE 802.3ba. Equipped with high-performance cooled LAN-WDM DFB transmitters and high-sensitivity PIN receivers, the transceiver ensures reliable performance for 100Gigabit Ethernet applications over links up to 10km, meeting the IEEE 802.3ba Clause 88 100GBASE-LR4 optical interface requirements.Designed according to the QSFP+ Multi-Source Agreement (MSA), this transceiver features a compact form factor, optical/electrical connections, and a digital diagnostic interface. It is built to withstand harsh external operating conditions, including extreme temperatures, high humidity, and EMI interference, ensuring robust and reliable performance in demanding environments.
