SFP28-25G-BIDI2 optical transceiver module

25GBASE SFP28 Optical Transceiver Module (1330nmTX/1270nmRX, 10km, simplex LC, SMF)

The SFP28 bidirectional optical transceiver is designed for bi-directional 25G serial data communications. There is a 1330nm transmitter and a 1270nm receiver in this 25G SPF28 module. They can work perfectly to reach up to 10 km transmission. Transmitter and receiver channels have a built-in clock and data recovery (CDR) that keeps the signal integrity even when transmitted over long distances. The optical module is ideal for campus networks, data centers, 25G Ethernet, and CPRI Option 10.

    FAQ

    In an optical receiver, what does BiDi stand for?
    BiDi stands for Bidirectional. It lets an optical transceiver like the SFP28 25GBASE BiDi use two wavelengths to transmit and receive data over a single cable. Its outgoing wavelength of 1270nm and receiving wavelength of 1330nm make it useful for networks that don’t have a lot of fiber resources.
    What’s the point of the SFP28 25GBASE BiDi module?
    BiDi modules, such as the SFP28 25GBASE, can send and receive data over a single fiber strand, which means that half as much fiber wiring is needed and makes fiber cable cheaper, network equipment easier to understand, and space more useful.

    What about multifiber cables? Does the SFP28 25GBASE BiDi adapter work with them?
    The SFP28 25GBASE BiDi is only for use with one fiber. One fiber can handle both sending and receiving lines, so it can be used in systems that want to be as efficient as possible while keeping the cable size as small as possible.

    What kind of fiber connection does the SFP28 25GBASE BiDi module work with?
    A SMF specific Simplex LC/UPC connection is used by the SFP28 25GBASE BiDi module. This connector works well and is effective for sending data over long distances.
