PRODUCT PRESENTATION

The PHILISUN QSFP28 100G LAN-WDM 80km ZR4 LC DX Transceiver is a high-performance module designed for 80km optical communication applications. It integrates a 4-lane optical transmitter, a 4-lane optical receiver, and a module management block with a 2-wire serial interface. The optical signals are multiplexed onto a single-mode fiber via an industry-standard LC connector.Built in compliance with the QSFP+ Multi-Source Agreement (MSA), the transceiver features a compact form factor, robust optical/electrical connections, and a digital diagnostic interface. It is engineered to withstand harsh external conditions, including extreme temperatures, high humidity, and EMI interference, ensuring reliable performance in demanding environments.
