MIL-STD-1553B Digital Data Bus Applications

Twinax /Triax connectors are used in military applications to protect data signals from extraneous noise through nonsignal-

carrying shielding. Interfacing connectors must provide contact surfaces isolated from each other and from their

outer shields. MIL-STD-1553B addresses twinax applications for computerized/multiplexed digital data distribution

systems servicing the many functions of Command, Control, Communications, Computers and Intelligence (C4I) which

was originally designed for military aircraft. MIL-STD-1553B applications are found in military surface ships, battle

tanks, helicopters, missiles, space vehicles, combat aircraft and in many ground applications such as data networks and

perimeter security for airports, armories, and other government installations.

The great advantages of additional information, automation and weight savings, which are necessary for the complex

demands of aircraft operations are realized by using a single transmission cable instead of the complicated, heavy,

dedicated multiple cable used in the past. A 78Ω twinax cable was selected to provide the transmitted digital information

with the needed protection from magnetic, electrostatic and electromagnetic pulse (EMP) interference. Complete

shielding of the twisted pair along the transmission path and all electrical contacts within multi-pin connectors must be

maintained.

Trompeter provides matching components of Twinax/Triax connectors and cable for improving the transmission

capabilities and interference rejection of data transmission systems. Trompeter components will meet or exceed MILSTD-

1553B requirements (for airborne and ground checkout) and MIL-STD-1760 External Stores.
