Data transmission - Import export

Axon' design and manufacture all components ( cables, couplers, connectors, acce) used in data transmission systems in compliance with the MIL-STD-1553 standard. This is the protocol of dialogue for strategic on-board systems for aeronautics, space and military applications. The range of products is called axobus®. Mil-std-1553 cables offered by Axon' are made with 22,24 and 26 AWG screened twisted-pair cables. The company also manufacture in-line couplers designed for weight and space saving. The company can also offer lightweight and removable couplers (ACC), size 8 triaxial contacts and various accesories including connector backshell, D-Sub or Micro-D halorings. Axon' Cable has a long-term flight heritage.

SpaceWire link is used to enable the reliable transmission of data at high speed (between 2 Mb/s and 400 Mb/s) from one unit to another. SpaceWire links are full-duplex, point-to-point, serial data communication links. Advantages Near constant total drive current (+3,5 mA for logic 1 and -3,5 mA for logic 0) which decreases switching noise on power supplies. High immunity to ground potential difference between driver and receiver. LVDS can tolerate at least ±1 V ground difference. High immunity to induced noise because of differential signalling normally using twisted-pair cable. Low EMI because small equal and opposite currents create small electromagnetic fields which tend to cancel one another out. Not dependent upon particular device supply voltages. Simple 100 Ohms termination at receiver. Power consumption is typically 50 mW per driver receiver pair for LVDS compared to 120 mW for ECL or PECL.
