    100G QSFP28 Single Lambda BiDi 10km-B Transceiver is a high-performance optical module designed for 100G Ethernet applications. It leverages Single Lambda Bidirectional  technology to transmit and receive data over a single fiber strand using two distinct wavelengths (e.g., 1331nm for Tx and 1271nm for Rx, or vice versa for "B" variant), achieving 10km reach on single-mode fiber (SMF). Compliant with QSFP28 MSA and IEEE 802.3 standards, it reduces fiber usage by 50% while maintaining 100Gbps bandwidth via PAM4 modulation and 4x25G NRZ electrical interface
