📝 Description
The Walsun 100G QSFP28 ER1 transceiver module is a high-performance, hot-swappable optical solution engineered for long-range 100 GbE applications. It meets the 100GBASE-LR1/ER1 and 100G Lambda MSA specifications, utilizing a single 1310 nm EML-based optical lane to deliver robust, high-speed data transmission across distances up to 40 km over standard single-mode fiber (G.652), with Forward Error Correction (FEC) enabled for reliable signal integrity
Electrically, it supports a full-duplex CAUI-4 interface carrying four 25 Gbps NRZ channels internally mapped to a 100 G PAM4 external signal, ensuring compatibility with modern 100 G networks. The module draws power from a 3.3 V supply and consumes up to 4.5 W, offering energy-efficient long-haul transmission.
The duplex LC interface facilitates straightforward deployment into standard telecom and data center environments. Built with compliance to QSFP28, RoHS, and stringent ESD protection (up to 8 kV), it ensures both regulatory adherence and robust physical resilience.The device supports digital diagnostic monitoring (DDM), enabling real-time tracking of key parameters like temperature, voltage, and optical power.
Designed to operate over a broad temperature range—from commercial to extended industrial profiles—it suits deployment in diverse environmental conditions. Overall, the Walsun 100G ER1 offers a dependable, high-capacity optical interconnect solution, ideal for long-distance backbone links, metro networks, and high-density data center infrastructure.
