BiDi Turning Dual to Single Fiber for 50% Fiber Savings

Overview

Almost all modern optical transceivers utilize two fibers to transmit data between switches, firewalls, servers, routers, etc. The first fiber is dedicated to receiving data from network equipment and the second fiber is transmitting data to it.

However, transceivers can now both transmit and receive data to and from interconnected equipment through a single optical fiber. This technology has led to the development of bi-directional transceivers, or BiDi transceivers for short.

Service providers, fiber owners, and primary users can effectively double the capacity of their fiber infrastructure without the need for SFP replacement.

RAD’s patented BiDi QSFP adaptor is a passive, small form factor dual to single fiber adapter that can be plugged into existing SFPs, providing immediate savings for 1G, 10G, 100G, and 200G fiber infrastructure. There is no need to replace the installed SFP and or encounter interoperability issues.

The benefit of BiDi is that it uses passive optical technology to redirect the light of two sources RX and TX into a single strand. In addition, BiDi is compatible with any SFP, 1G/10G/25G/40G/100G/400G rates. By implementing Bidi, this passive device resolves the issue seamlessly.
