AB - The feasibility of a passive bidirectional fiber optic bus and the packaging considerations of a bus access module have been studied. The bus uses 110/125 micrometers HCS fiber and passive integrated optic couplers for bus access. The access couplers are asymmetric and were fabricated using a Ag-Na ion exchange process. The asymmetry of the coupler was 5 dB, the launch loss to the bus was 6 dB and the tap-off loss to the node was 11 dB. With the integrated optics coupler it is possible to connect 6 nodes to the bidirectional bus. It is also possible to realize a simple, easy-to-use, and reliable bus access module for intramachine communication. The integrated optics coupler, a LED chip, and a PIN-diode chip and transceiver electronics are packaged in an electrical connector with a two-fiber optical cable pigtail. Active and passive components are butt coupled to the coupler. The 0.5 dB alignment tolerances for the fiber pigtails, the LED, and the PIN-diode chips are +/- 5 micrometers .
