Abstract
Abstract The present invention relates generally to a new interface and a method for making the same, and more particularly, to an optical fiber interface and a method for making the same. On a substrate having semiconductors, a receiver/transmitter connection is provided to interface with an optical fiber. Integral means for the fiber alignment, support and transit through a sealed environment is also provided. The substrate having the receiver/transmitter secured to it with the optical fiber end, is then enclosed in a housing.
