What is a Data Bus Coupler?

Think of a data bus coupler, as the “brain” of the MIL-STD-1553 system. It’s a critical part of the MIL-STD-1553 system, as it enables terminals to be added or removed. Data bus couplers are connected between MIL-STD-1553B bus and bus devices like controllers, monitors, and terminals. The purpose of a bus coupler is to reduce reflections, protect the bus, and maintain impedance of the bus by employing a transformer and a pair of fault-isolation resistors.

Data bus couplers are sometimes used to tap into the communication bus for testing or monitoring purposes. These couplers are integrated into the cable assemblies and allow for non-intrusive access to the data bus while maintaining the integrity of the communication. Bus couplers come in various sizes, depending on the number of stubs or connections they provide.

Different types of box couplers include:

Box Style: MilesTek box-style couplers offer a robust and rugged solution for military, aerospace, and commercial applications.

  • Features:
    • 1-8 stub coupler configurations
    • Each coupler can be a single, double, or non-terminated
  • Applications:
    • Military
    • Aerospace
    • Commercial

Inline: This type of bus coupler is used in airborne applications and offers the performance and utility of a box-style coupler in a smaller form factor.

  • Features:
    • 1-4 stub coupler configurations
    • Smaller form factor
    • Available in single, double, or non-terminated varieties
  • Applications:
    • Airborne

Bus Kits: MilesTek offers bus network kits that include bus couplers, terminators, and cable assemblies.

What is the MIL-STD 1553B Standard?

MIL-STD-1553 is a military standard published by the U.S. Department of Defense that defines the mechanical, electrical, and functional characteristics of a serial data bus. MIL-STD-1553 components are used for avionics, aircraft, and spacecraft data handling. The latest version of the serial local area network for military avionics, currently known as MIL-STD-1553B, was issued in 1978.

The MIL-STD-1553 standard encompasses applications for combat vehicles, ships, satellites, missiles, the International Space Station Program, and advanced commercial avionic applications.

MilesTek’s line of MIL-STD-1553 products meets all MIL-STD-1553 standards, including standards for 1553 revisions including MIL-STD-1553A and MIL-STD-1553C. MilesTek offers data bus couplers, cable assemblies, connectors, and more.
