What is BiDi Transceiver?

Wondering what Bidi Optical Transceiver means ? Then this article is for you ! It We are going to define what Bidi means, see its advantages and take a look at what it is available on the market today.

Definition of BiDi Transceiver

Bidi Transceiver stands for Bidirectional Transceiver. Bidi Transceivers or BWDM Transceivers (Bidirectional Wavelength Division Multiplexing) have WDM couplers, which allow them to carry two distinct channels in both directions (transmit and receive) on a single strand of fiber. For this reason, Bidi Transceivers must always be used in complementary pairs.

Because Bidi Transceivers can receive and transmit signal over only one fiber by using separate wavelength, they only need one port (see below photo). Traditional optical transceivers have two ports, one transmit port and one receive port.

Advantages of BiDi Transceiver

The main differences between Bidi Transceivers and Traditional Transceivers is that their technology allows them to transmit and receive over one fiber, reducing the number of ports to one. By having only one port, it reduces the cost of cabling. Indeed, Bidi Transceivers only require LC to LC simplex fiber cables. In addition to reducing the cost of cabling infrastructure, LC to LC simplex fiber cables also take less space and facilitate cabling management.
