Abstract: A method for the preparation of optical ferrules containing cylindrical members utilizes a guide receiving the cylindrical member, a sleeve receiving a piston therethrough, and a pin extending into the sleeve. The method also includes biasing to position the piston, using fill gates to dispense polymer into a defined cavity, and employing a containment which secures the components together. Injection molded optical fiber ferrules made according to the apparatus and process exhibit superior properties.

Abstract: An integral structure is provided for chemical processing and manufacture, in which a plurality of laminae are joined together and having inlet and outlet ports connected by a three dimensionally tortuous channel. Chemicals are introduced through the inlet ports and processed along the channel, with desirable product withdrawn through the outlet ports. The laminae are of materials selected to be compatible with the chemical process, from the group consisting of elements of groups III, IV or V of the Periodic Table, ceramics, glasses, polymers, composites and metals. Processes of manufacture of the apparatus and processes utilizing the apparatus are also disclosed herein.

Abstract: A connector assembly for connecting an optical fiber cable to a socket may be used in field with the advantages of precision connection and testing found in a manufacturing facility. The optical fiber cable has a first end, and a first predetermined length of a first bare optical fiber extends from the first end. The connector assembly comprises a ferrule for holding a second optical fiber. The ferrule has a first end, a second end, a central axis extending between the first and the second end and a hole extending along the central axis. A first portion of the second optical fiber is disposed in the hole and a second portion of the second optical fiber extends from the first end of the ferrule. The connector assembly also comprises a device for splicing the second portion of the second optical fiber to the first predetermined length of the first bare optical fiber.

Abstract: An opto-electronic component includes an opto-electronic device of either the edge or the surface active type mounted on a pedestal. A fiber is positionied by a positioning device apparatus. The positioning apparatus includes a superimposed first and a second arm. Each arm may be subdivided into a first and a second finger. The arms (and fingers) are fabricated from a crystalline material. The arms (and fingers) are biased toward a closed position. An optical fiber introduced into a channel defined by the superimposed arms is initially deflected so that a point on the end face of the fiber is placed into alignment with a reference axis. Further axial movement of the fiber through the channel causes the arms to move against the bias force to hold the point on the axis, regardless of the diameter of the fiber.

Abstract: A package for an opto-electronic component and associated pigtail is characterized by a notch formed in the sidewall of an open topped lower housing portion which interrupts the edge of the housing such that the component can be laid into the housing with the pigtail extending through the notch.

Abstract: A fiber optic device is provided with a feedthrough assembly adapted to decouple deflections imposed on the feedthrough from lensed end of a fiber disposed within the feedthrough assembly.
