Upstream and downstream data transmissions are completely separated and do not interfere with each other. Relatively simple design and. In the past, I have dealt with fiber optic network communication devices that utilize two fibers, RX and TX, each being dedicated to one direction. I was under the impression that two fibers are always required for bidirectional communication. By reading this blog, you will understand how SFP BiDi technology allows you to save fiber, reduce costs, and simplify installation while enabling your network to increase. A BiDi (bidirectional) transceiver is an optical module (commonly a QSFP28) that uses a single strand of fiber for 100G Ethernet communications. Simple design and low requirements. This approach is widely used in access networks, campus links, and metropolitan optical networks.
