  • Single-fiber bidirectional connection method

    Single-fiber bidirectional connection method

    Solving Your Fiber and Cost Challenges BiDi modules are transceivers that can send and receive at the same time over one fiber cable using two wavelengths. This full-duplex allows both directions without requiring a separate fiber for receiving. Unlike standard duplex SFPs that require two fibers—one for transmitting (TX) and one for receiving (RX)—BiDi modules integrate a WDM coupler to separate the wavelengths. BiDi SFP modules use a single fiber strand for both transmitting and receiving data. Learn how single-fiber bidirectional technology works, wavelength pairs, and when to choose BiDi over standard duplex SFPs.


  • Connection method between fiber optic cable and SC connector

    Connection method between fiber optic cable and SC connector

    Another common method is to splice on an SC pigtail by fusion splicing the cable fiber to a factory lead and protecting the splice in a tray.
