BiDi technology is used in a wide range of applications, including data centers, telecommunications, and video transmission. In data centers, BiDi technology can be used to increase the capacity of existing fiber optic cabling, enabling faster data transmission and reducing. The WDM system supports two transmission modes: single-fiber unidirectional and single-fiber bidirectional. Simple design and low requirements. Why Choose BiDi? Solving Your Fiber and Cost Challenges Why Choose BiDi? Solving Your Fiber. BiDi transceiver, a compact optical transceiver with WDM (wavelength division multiplexing) technology and SFP multi-source protocol (MSA) compliance, allows fast data transmission using a single fiber optic for both sending and receiving signals, saving resources and cutting infrastructure costs. Moreover, it enhances port efficiency, reduces hardware footprints, and opens the door to deeper optical integration. It is also known as bidirectional transmission, WDM-BiDi, or Bi-Directional Wavelength Division Multiplexing (BWDM).
