Extend, isolate, protect, and monitor — without compromising the bus
Sital Technology’s MIL-STD-1553 bus repeater is an intelligent MIL-STD-1553 / 1760 module designed to extend, isolate, protect, and monitor mission-critical data buses without compromising timing or signal integrity. Unlike simple analog repeaters, this MIL-STD-1553 bus repeater fully decodes and validates bus traffic, forwards only legitimate MIL-STD-1553 compliant messages, and blocks noise, distortion, and malicious activity.

How the MIL-STD-1553 bus repeater works
|
The MIL-STD-1553 bus repeater connects between two MIL-STD-1553 bus segments. Every message is decoded, validated, and re-transmitted with extremely low skew — preserving determinism across the link.
|
BUS SEGMENT TOPOLOGYSide A
Bus Controller (BC) and RTs
Side B
Remote Terminals (RTs) only
Processing
Decode → Validate → Re-transmit

MIL-STD-1553 bus repeater applications
Multiple RTs / StubSupport multiple RTs on a single stub — weapon pylons and munition clusters. |
Long Stub MitigationReliable operation on stubs longer than 20 ft. |
Bus SplittingSplit long buses to improve overall signal quality. |
RT IsolationElectrical and logical isolation of untrusted Remote Terminals. |
Cyber ContainmentContain threats between bus segments before they propagate. |
Signal QualitySide-to-side symmetry enhancement across the link. |
Engineered down to the physical layer

M1553 / M1760 bus repeater buffer — Avionics Plug
The Avionics Plug supports a single bus and is ready for flight after completing all flight-readiness qualifications. Two units are required for a full M1553 / M1760 implementation — one for Bus A, and a second for Bus B.
Specifications & form factors
Threats stopped at the bus boundary
Optional BC Firewall and SnS cyber protection keep malicious traffic from ever crossing between segments.
RT ImpersonationPrevents Remote Terminals from impersonating the Bus Controller. |
DoS BlockingBlocks denial-of-service attempts originating from the RT side. |
Traffic ContainmentPrevents malicious traffic from propagating across the bus. |
