    Description

    Asynchronous Local Fiber Optic RS-232 Multiplexor, 4-Port


    Quick Facts

  3. Time-division multiplexors with built-in fiber optic line drivers.

    4. 　

    Further Details

  4. The 4-port model supports speeds up to 64 kbps per port, the 8-port model supports speeds up to 38.4 kbps per port, and the 16-port model supports speeds up to 19.2 kbps per port.
  5. Duplex operation at distances up to 10,000 feet (3048 m) over point-to-point fiber cabling.
  6. Have dual ST multimode fiber connectors on their composite interfaces.
    Our Async Local Fiber Optic RS-232 Muxes are time-division multiplexors that support 4- or 16-channel speeds up to 64 kbps with the 4-port, up to 38.4 kbps with the 8-port, and up to 19.2 kbps with the 16-port muxes.

    If you're looking for an economical alternative to leased-line modems and statistical mulitplexors, a BLACK BOX® Async Local Fiber Optic RS-232 Mux is what you need. Get speed and savings in your async environment.
