Over the last few years DapTechnology has built a large variety of different AS5643 Repeater models. Starting with simple pass-through node-replacements the requirements grew with the different Aerospace programs. By now we have built about 25 different configurations. They span from multi-bus configurations to fiber-optics and EMI-hardened solutions.

Until now these AS5643 Repeater projects were handled strictly as custom solutions that originated from one particular off-the-shelf design and they were not really COTS. There was always a certain amount of engineering involved with a new customer requirement. But after having built so many different configurations we now feel confident to actively promote the entire product range. All the engineering is done and it is just a matter of bringing together the individual components. We put together a part numbering scheme that covers the most used configurations and should you still not be able to get your entire repeater project covered within that COTS offering then we can always put our expertise to work and assist you in defining, designing and building your special AS5643 Repeater.

DapTechnology has also built a variety of accompanying cable harnesses. We use qualified wires from W.L. Gore and are able to build suitable connector interfaces to your project. Please learn more about options in the section for cables and harnesses.

The most common usage scenario for repeaters is as a cable extension. As the length of cables for high-speed data transmission is limited a 1394 connection can only be extended by either using thicker wires or be adding a signal repeater. The latter is most effectively done via a physical layer device as it is the most effective form of signal reconditioning.

The following chart shows a summary of the relation of transmission speed, cable diameter and attainable length between nodes. For more details please refer to the SAE Standards and associated documentation.

Should the requirements exceed the permissable cable length and/or working with multiple repeaters is not feasible then converting the copper based cable extension into optical offers an alternative. Please see DapTechnology's MIL1394 Media Converter product(s).
