Dennis Craig Morrison - Lincolnton NC, US

International Classification:

G02B 6/38

Abstract:

A method of forming an optical fiber connector comprises preloading an adhesive plug into a ferrule bore of a ferrule. The ferrule bore extends between a first face and a second face of the ferrule and includes a large diameter bore section extending inwardly from the first face, a micro-hole section extending inwardly from the second face, and a transition section located between the large diameter bore section and the micro-hole section. The adhesive plug: a) is coupled to at least the transition section during the preloading, b) comprises an adhesive composition in a stable form, and c) blocks an entrance into the micro-hole section from the transition section. The method also comprises storing the adhesive plug in the ferrule bore for at least one day without coupling the optical connector to an optical fiber.

International Classification:

G02B 6/38

Abstract:

A method of forming an optical fiber connector is provided. The optical connector includes a body having a passage with a first section extending inwardly from a first face of the body, a second section extending inwardly from a second face from the body, and a transition section located between the first and second sections. The first section of the passage has a first width and the second section of the passage has a second width that is less than the first width. The method comprises loading an adhesive composition into the passage and storing the adhesive composition for at least one day without coupling the optical connector to an optical fiber. The adhesive composition is a meltable, substantially solid material maintained the first passage section, transition section, or both the second passage section and transition section.

International Classification:

G02B 6/38

Abstract:

An optical fiber connector preloaded with an adhesive is provided. The optical connector includes a body having a passage with a first section extending inwardly from a first face of the body, a second section extending inwardly from a second face from the body, and a transition section located between the first section and the second section. The first section of the passage has a first width and the second section of the passage has a second width that is less than the first width. An adhesive composition is located within the transition section of the passage and is configured to bind an optical fiber to an inner surface of the second section following melting and solidification of the adhesive composition.

International Classification:

G02B 6/38

Abstract:

A method of terminating an optical fiber involves providing a ferrule having a front end, a rear end, a ferrule bore extending between the front and rear ends, and a bonding agent disposed in at least a portion of the ferrule bore. The method also involves applying energy to heat the bonding agent. An end section of an optical fiber is inserted into the ferrule bore and through the bonding agent when the bonding agent is heated. The end section of the optical fiber includes a primary coating prior to insertion into the ferrule bore. During insertion of the end section of the optical fiber through the bonding agent, the heated bonding agent thermally removes at least a portion of the primary coating during so that the optical fiber can be secured in the ferrule bore with the bonding agent.

Assignee:

Corning Optical Communications LLC - Hickory NC

International Classification:

G02B 6/38

Abstract:

An optical fiber connector includes a ferrule configured to receive an optical fiber. The ferrule has a fiber bore and a storage location interior to the ferrule and adjacent to the fiber bore. The storage location comprises a funnel-shaped portion that is directed toward the fiber bore. An adhesive material is positioned in the storage location of the ferrule. The adhesive material is a dry and solid material.

Abstract:

Thermal removal of optical fiber coatings by insertion through heated ferrules to form ferrule assemblies for fiber optic connectors, and related assemblies are disclosed. An optical fiber includes a glass fiber, having a cladding and core, surrounded by a protective coating. By removing the coating at an end portion of the optical fiber, the end portion may be precisely positioned and secured within a ferrule to enable reliable optical communications. The coating may be thermally removed, or substantially thermally removed, by inserting the optical fiber through a rear opening of the ferrule which has been heated above a temperature sufficient to change the coating to a non-solid state. In this manner, the coating may be efficiently removed from the end portion of the optical fiber while being inserted into the ferrule bore of the ferrule to enable efficient forming of a ferrule assembly for a fiber optic connector.
