Abstract
MIL-STD-1553B (MILBUS) as a network standard for military systems – with a data rate of 1 Mbps – comes across as (and is) a little out-dated, but is still well-known for its reliability, safety and the strong determinism of a real time bus protocol. The strong electromagnetic immunity of MILBUS has given rise to a number of new applications for military and civil programmes, as well as some lightweight applications with unshielded cables.
But the future will lead to higher speeds and we have made several efforts to implement the excellent MILBUS command/response protocol in modern and faster physical networks. The data rate capability for EFABUS / STANAG 3910 was raised by means of a parallel network. The result was the optical EFABUS Express. MIL-STD-1760E for stores defines a switched electrical Fibre Channel interface for mapping MIL-STD-1553 messages and for 1 Gbps mass data transfers. A fibre optic interface will follow. Another concept is the implementation of a collision- and delay-free protocol at Ethernet level.
Another option, especially for upgrade programmes, is E1553 / STANAG 7221, whereby available MILBUS cables are retained for a Broadband Real-Time Data Bus (B-RTDB) with Multi-Carrier Waveform (MCW) protocol for higher data rates.
