Single-fiber Bidirectional Transceivers
An Introduction to BiDi Transceivers
In the world of transceivers, BiDi stands for Bi-Directional. In terms of SFPs, BiDi transceivers transmit at one wavelength and receive at another. This is different from standard transceivers which use the same wavelength for transmit and receive. BiDi SFPs connect to a fiber cable using only one simplex port, whereas standard transceivers have duplex fiber ports.
How Bidirectional Transceivers Work
BiDi modules enable two-way communication over a single optical fiber by using a WDM (wavelength-division multiplexing) filter component in the transceiver. BiDi transceivers transmit optical signals at one wavelength and receive them at a different wavelength, allowing for bi-directional transmission. For instance, BiDi transceiver A in the figure transmits 1310nm wavelength signals and receives 1490nm wavelength signals, while BiDi transceiver B does the opposite. BiDi transceivers must be used in pairs due to this configuration – identifying as an Upstream (U) and Downstream (D) to the connection.

Different versions of SFP BiDi Transceivers
SFP BiDi Transceivers
SFP BiDi transceivers are specifically intended for deploying 1.25 Gigabit Ethernet networks. Typically, short to medium-distance BiDi networks spanning 10km to 40km use a wavelength combination of 1310nm/1490nm, while long-haul BiDi SFP applications spanning 80km to 120km usually employ a wavelength combination of 1490nm/1550nm.
SFP+ BiDi Transceivers
SFP+ BiDi transceivers are specifically engineered to support 10 Gigabit Ethernet deployments. The most commonly used wavelength combination for 10G SFP+ BiDi transceivers is 1270nm/1330nm, which is employed for short to medium-distance optical fiber transmission spanning 10km to 60km. Conversely, a wavelength combination of 1490nm/1550nm is used for long-haul BiDi SFP+ applications spanning 80km to 100km.
SFP28 BiDi Transceivers
The 25G BIDI SFP28 transceivers are designed to enable bi-directional 25G serial optical data communications using either 1270nm/1330nm wavelengths. These modules are ideal for use in 25G Ethernet and CPRI applications, particularly within 5G mobile networks.
