MIL-STD-1553 Data Bus Couplers

There are two types of couplers to choose from; The In-Line type or the flange-mounted BNC connector Box-type.

In-line couplers generally offer significantly lower weight and are usually mounted by lacing them into cable bundles or securing them to bulkheads with a clamp.

Box-type couplers, although heavier, offer the advantage of easy fault isolation, flexibility in updating when a bus configuration changes, and are easy to install and repair.
