## Abstract

An intelligent opto-bus including an optical/electrical connector with a display. An array of photonic components is mounted on a base and coupled to external electrical connections of the base. Electronics are mounted on the base and coupled to the array for sensing the operation of the array and the status of optical signals supplied to optical ports of the array. A display is coupled to the electronics to provide a visual indication of the operation of the array and the status of optical signals supplied to the optical ports of the array. The base is molded with a well and grooves. The electronics and display are positioned in the well and the grooves form optical waveguides that communicate with a fiber ribbon.
