Filed:

Jul 10, 1992

Appl. No.:

7/911522

Inventors:

Gregory A. Perry - Dunwoody GA

Assignee:

Peachtree Fiberoptics, Inc. - Norcross GA

International Classification:

G02B 618

US Classification:

385124

Abstract:

A process for the manufacture of a multi-layer polymer optical fiber having a graded optical refractive index profile. This fiber is comprised of an inner core layer, one or more intermediate layers and an outer clad layer, each layer being extruded from a polymer material. All layers are arranged in a concentric configuration, with the outer clad layer enclosing all other layers.

Abstract:

A method for fabricating a single mode fiber preform is described. The method consists of placing a core rod in a glass lathe, sliding a barrier tube over the core rod, partially attaching the barrier tube to the core rod, rotating and heating the barrier tube, and traversing the heat source until the barrier tube collapses onto the core rod. A second tube of high purity quartz called a primary jacket tube is then slipped over the combination fabricated from the core rod and barrier tube, rotating and heating the primary jacket tube, and traversing the heat source until the primary jacket tube collapses onto the barrier tube. A third tube of high purity quartz called a secondary jacket tube is then slipped over the combination fabricated from the core, barrier tube and primary jacket tube, partially attaching the secondary jacket tube to the primary jacket tube, rotating and heating the secondary jacket tube, and traversing the heat source until the secondary jacket tube collapses over the primary jacket tube to form a single mode fiber preform.
