Abstract

The design of fiber optics transmit and receive hardware requires that the fiber optics cable have direct access to the solid state devices that convert between light and electrical impulses (Photonics devices). To accomplish this task it is necessary to maintain the critical alignment of the fiber optics connector and the junctions ofthe photonics devices during mating and de-mating. The tight mechani- cal tolerances required to maintain this alignment can result in a great deal of stress on the assembly which holds the photonics devices. At the same time, the high frequency of the electrical signals used to power and detect the photonics devices require extremely low capacitance, inductance and cross talk in the electrical interconnect circuitry. The Flexible Photonics Carrier Electrical Attach Substrate described below accomplishes both mechanical and electrical integrity ofthe module.
