Abstract: A fiber array faceplate for receiving, precisely positioning and immobilizi ng bare optical fiber. The faceplate includes a plate arrangement of at least t wo mutually parallel plates each having an array of fixed apertures. At least one of the plates is movable in translational motion such that the at least two plates collective ly define an array of adjustable-size apertures that can open wide enough to readily receive bare optical fiber and then decrease in size to immobilize the received optical fiber.

Abstract: An assembly for protecting the active electronic components of an electronic product from the environment and electromagnetic interference (EMI). A method is described where the assembly is formed by providing a metallized flexible enclosure around the electronic product, such as a printed circuit board, and subsequently sealing the metallized flexible enclosure, such that separable connectors can be readily accessed without violating the integrity of the seal. The metallized flexible enclosure includes multiple layers of polymeric materials that provide diffusion barrier properties and a metallic layer that provides both diffusion barrier properties and EMI shielding capabilities. The multiple layer sheet is patterned to optimize the diffusion barrier properties and EMI shielding capabilities. Further, the multiple layer sheet enables efficient, high volume production. Thus, electronic products can be provided with an assembly having an environment protection capability and EMI shielding capability amenable to reliable and cost effective high volume production.
