Guide to BiDi Optical Transceiver

Pluggable optical transceivers typically use two fibers to send and receive optical signals between switches, firewalls, servers or routers. One fiber is to receiving data from networking equipment, and the other is to transmit data to the networking equipment. However, a new class of optical transceiver—BiDi transceiver uses only a single fiber to send and receive signals. The reduction in fibers leads to substantial cost-saving, especially in high-density applications. Besides that, BiDi transceivers also possess some unique features, which will be illustrated in the following article.

Pros and Cons of Fiber Optic Networks

With the obvious advantages, fiber optic cables have become an essential component in fiber optic communications. Terminated with connectors on ends, these cables (e.g. SC-SC fiber cable) carry the light signals generated by the transmitter to the receiver.
