MIL-STD-1553 is a DOD Military (MIL) Standard (STD), which defines
both the Mechanical, Electrical, and Functional characteristics.
MIL-1553 may be transformer coupled. The schematic shows how different devices on the MIL-STD-1553 interface bus are connected.
Note the Isolation Resistors used on each leg of the coupling transformer, which feeds the isolation transformer.
MIL-1553 uses low power pulse transformers per MIL-PRF-21038.
Which defines a number of transformer styles, windings, taps and [through-hole] packages.
The transformer shown here has a 1-to-1 turns ratio and no voltage taps.
Note all slash sheets but /27 & /28 have been cancelled without replacement.

MlL-STD-1553B does not specify the type of connector used to interconnect cables that make up a network. Notice 2, paragraph 30.10.3, however, specifies that, for applications that use concentric connectors or inserts for each bus [Pin Out info]: the center pin of the connector or insert shall be used for the high (positive) Manchester hi-phase signal. The inner ring shall be used for the low (negative) Manchester hi-phase signal.
There are currently two types of connectors in general use.
1: a multi-pin connector that comes in various styles including circular,
rectangular, and rack and panel.
2: is the discrete concentric triaxial design.
