100G QSFP28 Single Lambda BiDi LR 10km-A Transceiver
Posted on 2025-07-11

100G QSFP28 Single Lambda BiDi 10km-A Transceiver is a high-performance, compact optical module designed for 100 Gigabit Ethernet applications. It utilizes Single Lambda technology to transmit and receive data over a single wavelength (typically 1310nm) on one fiber strand, enabling bidirectional (BiDi) communication. With a reach of up to 10 kilometers over single-mode fiber (SMF), it complies with the 10km-A standard for reliable, cost-effective connectivity.
