BiDi SFP+ Modules
When compared to traditional SFP transceiver, BiDi SFP are installed in matched pairs. One for the upstream (“U”) direction, and the other for the downstream (“D”), each part is transmitting at a different wavelength. The main 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 diplexers, which combine and separate data transmitted over a single fiber based on the wavelengths of the light. 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).Unlike common SFP transceiver, BiDi SFP transceiver is only with one port which uses an integral WDM coupler to transmit and receive signals over a single strand fiber.
At present, this single fiber BiDi transmission gradually becomes a popular and cost-effective solution for today’s data center and IT infrastructure, because it helps to maximize the capacity and usage of optical fibers. However, the BiDi SFP is usually used in FTTx deployment P2P (point to point) connection.It is specially designed for the high performance integrated duplex data link over a single optical fiber. BiDi SFP interfaces a network device mother board (for a switch, router or similar device) to a fiber optic or unshielded twisted pair networking cable. Nowadays, it is one of the most popular industry formats supported by many fiber optic component vendorsThe 10G SFP+ modules are just as important as the 10GBASE- CWDM SFP+, 10GBASE SFP+, SFP+ BiDi and 10GBASE-DWDM SFP+ optical transceiver modules listed above. These optical transceivers are based on two different wavelengths. They help you achieve a transmission of 10G through a single fiber cable. You can expect the BiDi optical module to have a wavelength of 1310nm/1550nm, 1510nm/1590nm or 1310nm/1490nm.
