Abstract
An optical harness assembly and method are provided. The optical harness assembly includes at least one optical harness cable having a termination end; at least one electrical connector having connector pins; and at least one active connector conversion unit coupled between the termination end of the optical harness cable and the electrical connector. A method for retrofitting an optical harness assembly into an existing platform is disclosed. The method includes removing a legacy wiring harness; installing an optical harness assembly having electrical connectors and an active connector conversion unit; and testing the compatibility of connector pins of the electrical connector to the active connector conversion unit. In another embodiment the method includes: identifying electrical signals present on each pin of each electrical connector presentation; programmatically adjusting an interface based on the identified electrical signals present; and mapping the electrical connector signals to digital signals. Alternatively, the method may further include: providing a personality adaptor coupled between the electrical connector pin outs and signal conditioners; configuring the personality adaptor based on the identified electrical signals present on each pin out of each electrical connector presentation; and providing configured electrical connector presentation signals to the interface.
