100G OTU4 BiDi QSFP28 is an optical transceiver module designed for high-speed network interconnects. It employs Bi-Directional (BiDi) technology, enabling full-duplex 100Gbps communication over a single strand of single-mode fiber. Utilizing wavelength-division multiplexing, it transmits at 1270nm and receives at 1330nm on one end, thereby saving 50% of fiber resources and significantly alleviating pressure on fiber infrastructure.
100G OTU4 BiDi QSFP28 strictly complies with the telecom-grade OTU4 protocol standard, supporting a line rate of approximately 111.8 Gbps, which ensures seamless integration into optical transport networks for efficient and reliable long-distance transmission. With the mainstream QSFP28 form factor, it offers a compact design and low power consumption, providing a high-density port solution. Consequently, this module is primarily deployed in data center interconnects, metropolitan area networks, and telecommunication aggregation layers.
The 100G OTU4 BiDi QSFP28 Optical Transceiver is a high-performance single-fiber bidirectional optical module designed for high-capacity optical transport networks, data center interconnects, and long-distance transmission applications.
