Driving the need for optics in flight control are the issues of wire weight, HIRF, and system bandwidth. With the advent of advanced Vehicle Management System (VMS) systems and the higher level of functional and physical integration of subsystems such as the More Electric Aircraft (MEA) and the Subsystem Utility Integration Technology (SUIT) program, optics in flight control offer attractive system benefits. Advanced VMS control functions generate large quantities of data to be transmitted over the VMS buses for processing. This paper will address the implementation of a module that will support the high throughput requirements of an advanced VMS system. The module is defined as the Optical Bus Interface Module (OBIM) and utilizes the AS1773A 20 mbps fiber optic bus for the VMS system bus. In addition, the module supports 5 mbps fiber optic Cross Channel Data Links (CCDLs) for the exchange of flight critical data in redundant architectures.
