Robert G. Wiley - Franklin TN, US

Assignee:

3SAE TECHNOLOGIES, INC. - Franklin TN

International Classification:

G02B 6/255

US Classification:

385 96

Abstract:

A multi-stage fiber processing system comprises first and second fiber holders configured to hold respective portions of at least one fiber and a plurality of heat sources arranged between the first and second fiber holders and configured to provide a heat zone that axially extends about the at least on fiber. The first and second fiber holders can be configured to translate away from each other for tapering. The plurality of heat sources can include two 3 electrode heat sources that deliver an extended, substantially isothermic heat field axially about the fiber. All but one heat source can be turned off to splice the fiber. The two 3 electrode heat sources can generate 9 arcs to from the heat zone, wherein arcs between the two 3 electrode heat sources can be rotated about the at least one fiber.

International Classification:

G02B 6/255

US Classification:

385 96

Abstract:

Provided is a thermal mechanical diffusion system and method. In accordance with the present invention, one end of a fiber under tension is vibrated while a portion of the fiber is heated. A push-pull action of one end of the fiber forces increased (or rapid) diffusion of dopants in the portion of the fiber that is in a heat zone, which receives the heat. By controlling the amplitude and frequency of the vibration, a diffusion profile of one or more fibers can be dictated with precision. Heat sources having narrower thermal profiles can enable greater precision in dictating the diffusion profile. As an example, this can be particularly useful for creating a diffusion taper within a fiber to be spliced, where the taper is a result of thermal expansion of the fiber core. Diffusion can occur much more rapidly than is typical.

Inventors:

- Franklin TN, US
John Lower - Franklin TN, US
Brett Clark - Whites Creek TN, US

International Classification:

C03B 37/025
C03B 37/028

Abstract:

Provided is a system for and a method of processing an optical fiber, such as tapering an optical fiber. The method includes receiving fiber parameters defining characteristics of an optical fiber, modeling an idealized fiber based on the fiber parameters to establish modeled data, and establishing processing parameters. A processing operation is performed on the optical fiber according to the processing parameters to produce a resultant fiber. Aspects of the resultant fiber are measured to establish measured data. The measured data and the modeled data are normalized to a common axis and a difference between the two is determined. The processing parameters are adjusted based on the differences.

International Classification:

G02B 6/255
F16M 11/32
F16M 11/12
F16M 11/18

Abstract:

A parallel position manipulator includes a top plate, a baseplate and a plurality of prismatic joint actuators. Each actuator includes an actuator joint having five Degrees of Freedom (DOF) at either the base plate or the top plate. When one or more of the actuators extends or contracts, the pivot points, or five DOF actuator joint, of the remaining actuators are allowed to shift in any axis other than that actuator's primary axis of motion.

International Classification:

C03B 37/10
C03B 37/07
H05B 7/18

Abstract:

An electrical discharge, suitable for heating optical fibers for processing, is made in a controlled partial vacuum, such that saturation of available ionizable gas molecules is reached. The workpiece temperature is thereby made to be a stably controlled function of the absolute air pressure and is insensitive to other conditions. A system and method accomplishing the foregoing are provided.
