Using bidirectional transceivers allows you to separate the data in each direction without requiring two fibers. This means you can use one strand for both transmitting and receiving, doubling your network capacity while saving on the cost of additional fiber cabling.
A bidirectional transceiver utilizes WDM (wavelength division multiplexing) technology to separate the optical signals in each direction based on their different wavelengths. As such, these hot-plug devices are sometimes known as WDM transceivers or diplexers. They are typically deployed in matched pairs – one for upstream transmissions and the other for downstream transmissions – to ensure they operate correctly together.
100G Singlemode BiDi
The SFP+ bidirectional transceiver is used to connect switches, routers, and storage equipment within a data center or between them. It adheres to the 100G CWDM4 MSA industry standard, supporting connections up to 10km over single-mode fiber.
As the need for low-latency east-west traffic between servers grows, datacenter owners are upgrading to 100Gb/s. Using 100G BiDi optics makes this possible over existing multimode fiber infrastructure by utilizing the same optical wavelength for both transmitting and receiving. This eliminates the need to invest in new fiber and reduces datacenter construction costs. We have a wide selection of 100G BiDi transceivers available for various speeds and connector options. Check out our complete guide to 100G bidirectional optics to learn more about the technology and find the right fit for your data center.
