Thông tin sản phẩm

- The OBE 1553 system allows the bi-directional connection between a Remote Terminal Unit and a MIL-1553B bus by means of an optical fiber link.
- TESEO OBE1553 constitutes a fiber optic extension of the 1553B avionic bus. By means of an OBE1553 a bidirectional connection can be made between a Remote Terminal Unit and a MIL-STD-1553B bus with the advantage of the electrical isolation and noise immunity provided by the fiber cable. A typical application is the connection of an avionic equipment to a distant bus.
- The system is protocol transparent because the transmission is analog and the received signal is not regenerated: at each receiving side of the link the signal wave shape is unchanged like also its S/N ratio. A bus extender is formed of two transceivers, the OBE1553BC on the side of the bus, and the OBE1553RT on the side of the Remote Terminal Unit.
- The transceivers look the same, but are not identical because some electrical differences exist to allow them to operate in the right way. Each transceiver is a plug-in module for insertion in an unshielded chassis IMAGE-MF (3 slots) or IMAGE-MF1 (7 slots) containing power supply, ON/OFF switch and associated indicator. Each transceiver occupies one slot. A redundant bus configuration occupies two slots in each of the two mainframes. The bifiber cable (200 um, ST connectors) introduces a delay of 10 nsec per meter, delay to be added to the 500 nsec caused by the transceivers.
