PRODUCT PRESENTATION

The PHILISUN QSFP28 100G LAN-WDM 40km ER4 LC DX is a high-performance 100Gb/s transceiver module designed for optical communication applications compliant with the Ethernet 100GBASE-ER4 standard. It converts four 25Gb/s electrical input channels into four LAN WDM optical signals, multiplexing them into a single channel for 100Gb/s optical transmission. On the receiver side, it de-multiplexes the 100Gb/s optical input back into four LAN WDM optical signals and converts them into four electrical output channels.The central wavelengths of the four LAN WDM channels are 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm, consistent with the LAN WDM wavelength grid defined in IEEE 802.3ba. Equipped with high-performance cooled LAN WDM DFB transmitters and high-sensitivity APD receivers, the module ensures exceptional performance for 100Gigabit Ethernet applications over links up to 40km.Designed according to the QSFP+ Multi-Source Agreement (MSA), the transceiver features a compact form factor, reliable optical/electrical connections, and a digital diagnostic interface. Built to withstand extreme operating conditions, including high temperatures, humidity, and EMI interference, it ensures robust and reliable performance in demanding environments.
