ABSTRACT:
Electro-optical interface connections between electronic modules are used for data transmission rather than conventional pin and socket connections. Each module has on its top a number of diode pairs, one of the diodes transmitting light, and the other receiving light, and converting the light into electrical pulses. A data bus block is mounted across the tops of the modules. The data bus block has corresponding diode pairs that align with the diode pairs in the modules. Light pulses may be transmitted from the modules to the data bus block onto parallel data bus lines, then transmitted back to other modules from the data bus lines. On another side of the module, a serial electro-optical connection using a diode pair transmits to and receives light pulses from a fiber optic line for communicating with modules other than in the cluster.
