Problems solved by technology

Since the diameter of the fiber bundle can vary greatly with the size of the fiber and the production conditions, when crimping the ferrule onto the fiber bundle, if the fiber bundle diameter is small, the connection between the two will be loose, and If the fiber bundle diameter is too large, it will damage the outer fiber

Embodiment Construction

[0019] In the following description, specific terms are used for convenience and should not be construed as limiting the present invention. The term "a" is defined to include one or more of the referenced item unless specifically stated otherwise. The term "array" here includes any type of ordered, two-dimensional arrangement of fiber ends, such as flexible imaging fiber bundles.

[0020] Referring now to FIG. 1 , a flexible fiber optic cable 10 is shown. The cable 10 includes a plurality of optical fibers 12 grouped together to form a fiber optic bundle 14 having a flexible central portion 15 and two inflexible end portions 16, 18, the optical fibers 12 within the flexible central portion 15 can be positioned relative to the optical fibers Adjacent optical fibers 12 within bundle 14 are moved and multiple optical fibers 12 within inflexible ends 16, 18 are spliced ​​together in a predetermined arrangement, such as the arrangement shown in FIG.

[0021] As shown in FIG. 3, e...

Abstract

A flexible optic fiber cable is provided having a plurality of optic fibers grouped together as a fiber bundle with a flexible center section, in which the optic fibers are moveable relative to adjacent fibers in the fiber bundle, and two non-flexible end sections. Each of the two non-flexible end sections includes a generally uniform thickness protective layer extending over an outer surface thereof starting at a position spaced inwardly from a free end of the end section. A ferrule is located around and in an interference fit with the protective layer so that the end section is centered in the ferrule. An adhesive is located between the ferrule and the non-flexible end section from the position spaced inwardly from the free end of the end section to the free end thereof to connect the ferrule to the non-flexible end section.

Description

technical field [0001] The present invention relates to imaging optical fibers, and more particularly to an optical fiber cable having a flexible central portion and non-flexible end portions retained within a protective ferrule. Background technique [0002] In the field of imaging fibers and optical fibers for signal transmission, it is known to manufacture fiber optic bundles by heating and drawing glass fibers that are separated or sealed by leachable spacers to form fused fiber bundles. The ends of the fiber bundle are masked or protected, and the fiber bundle is then placed in a leachant that leaches leachable spacers from the center of the fiber bundle between the protected ends. This results in the central portion being flexible. Preferably the fiber optic bundle is covered by a protective sheath to form a flexible fiber optic cable. [0003] Typically, a collar or sleeve is attached to the non-flexible end in order to protect the end from damage and to allow the e...
