What is a BiDi SFP?
What Is BiDi SFP? BiDi SFP transceiver is a compact optical transceiver module which uses WDM (wavelength division multiplexing) technology and is compliant with the SFP multi-source agreement (MSA). It is specially designed for the high performance integrated duplex data link over a single optical fiber.
Main Differences Between BiDi SFP and Traditional SFP
The primary difference between BiDi SFP and traditional two-fiber SFP transceiver is that BiDi SFP is fitted with wavelength division multiplexing (WDM) couplers, also known as diplexer, which combine and separate data transmitted over a single fiber based on the wavelengths of the light. That's why BiDi SFP has only one port, while the traditional SFP module is generally with two ports. One is TX for the transmitting port, and the other is RX for receiving port.
Another difference between common SFP and BiDi SFP is upon optical sub-assemblies, major cost components of a fiber optic transceiver. As we all know, a common SFP usually has two optical sub-assemblies - the transmitter optical sub-assembly (TOSA) and the receiver optical sub-assembly (ROSA), but BiDi SFP only contains one optical sub-assemblies - BOSA (bi-directional optical sub-assembly), which acts the role of TOSA and ROSA, but with different working principle.
