10G BiDi SFP+ is an optical transceiver that uses bidirectional (BiDi) technology to transmit and receive 10G data signals over a single strand of single-mode fiber. It employs two different wavelengths on the same fiber strand, effectively doubling fiber capacity. This hot-pluggable module is ideal for fiber-scarce environments, enabling cost-efficient network upgrades in metropolitan, access, and enterprise networks while maintaining full 10G performance.
