The ComNet FDX4D(M,S)1 Series data transceiver series provide transmission of four bi-directional data channels over one optical fiber and are ideal for use in unconditioned roadside or out-of-plant installations. The data channels can be set independently for RS232, RS422 and 2 or 4-wire RS485 with tri-state support.

Features for FDX4D Series

  • Robust design ensures extremely high reliability in unconditioned out-of-plant environments
  • Status indicating LEDs provide rapid indication of critical operating parameters.
  • Available with FC or ST Optical connectors
  • Supports RS232, RS422, and 2 or 4-wire RS485 with tristate data interfaces
  • Four bi-directional data channels
  • Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events.
  • ComFit standard form factor is interchangeable between stand-alone or rack mount use.
  • Tested and certified by an independent laboratory for full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/ TS-2 and the Caltrans Specification for Traffic Signal Control Equipment.
  • Standard ComFit models are hot-swappable.
  • Lifetime Warranty
