PRODUCT PRESENTATION

The PHILISUN QSFP28 100G LAN-WDM 10km LR4 LC DX OUT4 is a 100Gb/s transceiver module designed for optical communication applications, compliant with OTU4 411-9D1F requirements as specified in ITU-T Recommendations G.959.1, G.709, and Supplement 39 (G.sup39). The module converts four 28Gb/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, in accordance 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 module ensures exceptional performance.Designed according to the QSFP+ Multi-Source Agreement (MSA), this transceiver features a compact form factor, robust optical and electrical connections, and a digital diagnostic interface. It is engineered to operate reliably under harsh conditions, including extreme temperatures, high humidity, and EMI interference, making it ideal for demanding environments.
