1.25G BiDi SFP 1310/1550nm 3KM LC Optical Transceiver is a compact, high-performance single-fiber bidirectional module designed for efficient fiber infrastructure utilization. It operates on two different wavelengths - transmitting at 1310nm and receiving at 1550nm (or vice versa, depending on the model variant) over a single strand of standard single-mode fiber. 

This innovative bidirectional technology effectively doubles the fiber capacity by enabling simultaneous data transmission and reception through the same fiber. 

Supporting data rates up to 1.25 Gbps with a transmission distance of up to 3 kilometers, this hot-pluggable SFP transceiver is ideally suited for space-constrained applications where fiber resources are limited, such as FTTH access networks, cellular backhaul, and enterprise network expansions. Fully compliant with relevant SFP MSA standards, it provides a cost-effective solution while maintaining reliable performance in Gigabit Ethernet applications.
