Description
The 100G QSFP28 BiDi ER1-40 Optical Transceiver is a long-reach bidirectional module designed for 100GBASE-ER1-40 Ethernet applications over a single strand of single-mode fiber. Using dual wavelengths of 1304nm and 1309nm for bidirectional transmission, it supports distances of up to 40km while reducing fiber resource requirements and simplifying long-distance network deployment. The module combines PAM4 optical modulation, an EML laser transmitter, and an APD receiver to provide reliable optical performance for extended-reach links. With a QSFP28 form factor, CAUI-4 host electrical interface, Simplex LC optical interface, I2C-based digital diagnostics, and single +3.3V power supply, it is suitable for long-distance data center interconnects, telecom infrastructure, and high-density 100G Ethernet networks.
