　　OBE1553 connects remote terminal unit and MIL-1553B bus through optical fiber link to realize bidirectional connection. The OBE 1553 constructs fiber optic line extensions for the Aeronautical Equipment Bus 1553B. The remote terminal unit and the MIL-1553B bus are connected through a fiber optic link to achieve bidirectional connection, resulting in electrical isolation and noise immunity. Typically used to connect aviation equipment and remote buses. Since the transmission is similar, the received signal will not be repeated, and the system protocol is transparent. The signal waveform at the receiving end of the link does not change as does its signal-to-noise ratio.

　　A bus extender consists of two transceivers. OBE1553BC is on the bus side and OBE1553RT is on the remote device side. The two transceivers appear to be the same, but they are actually different due to differences in the internal electronics. Each transceiver is a plug-in module, containing power supply, switch and associated LEDs, to be plugged into an unshielded case such as IMAGE-MF (3 slots) or IMAGE-MF1 (7 slots). Each transceiver occupies one slot, and the remaining configuration devices occupy the remaining slots. Dual fiber cables (200um, ST connectors) cause a delay of 10nsec per meter, which is added to the 500nsec delay caused by the transceiver.
