Abstract

DC60 (04/01/48) herein discloses an optical coupling device comprising (a) fiber optic cables, each of which has two ends and contains at least one optical fiber enclosed in a protective sheath, where the diameter of this fiber optic cable is greater than the diameter of the optical fiber and where at least the protective sheath at one end of this fiber optic cable is removed to expose the optical fiber; (b) a spliced assembly enclosing one end of the fiber optic cable and the optical fiber, where the optical fibers in this spliced assembly lie parallel to each other and have a first pitch; and (c) a cap attached to the spliced assembly. This cap has a number of internal grooves with a second pitch. The first pitch of this optical fiber is essentially equal to the second pitch of this cap. Herein discloses an optical coupling device comprising (a) fiber optic cables, each of which has two ends. and consists of at least one optical fiber enclosed in a protective sheath, where the diameter of this optical fiber cable is greater than the diameter of the optical fiber, and where at least the protective sheath at one end of this optical fiber cable is removed to expose the optical fiber; (b) a spliced assembly which encloses one end of the optical fiber cable and the optical fiber, where the optical fibers in this spliced assembly lie parallel to each other and have a first pitch; and (c) a cap attached to the spliced assembly, which has a number of internal grooves with a second pitch, where the first pitch of this optical fiber is essentially equal to the second pitch of this cap.

Claims (15)

1. An optical connector consisting of (a) a number of optical fiber cables, each cable having two ends and containing at least one optical fiber enclosed in a protective sheath, where the diameter of this optical fiber cable is greater than the diameter of the optical fiber and where at least the protective sheath at one end of this optical fiber cable has been removed to expose the optical fiber; (b) a spliced assembly enclosing one end of the optical fiber cable and the optical fiber, where the optical fibers in this spliced assembly lie parallel to each other and have a first pitch; and (c) a cap attached to the spliced assembly. This cap has a number of internal grooves of a second pitch, where the first pitch of the optical fiber is substantially equal to the second pitch of this cap. 2. An apparatus under claim 1 in which the optical fibers in this assembled, threaded unit touch or nearly touch each other. 3. The device under claim 1 in which the pre-wired assembly has a geometric shape that will not damage the minimum bending radius of the optical fiber. 4. Equipment under claim 1 where this fiber optic cable is a cable of fibers that is rigidly bonded or a cable of fibers that is strengthened. 5. Equipment under claim 1 where this wired assembly is further assembled by mechanical locking means. 6. The device under claim 1, in which this pre-wired assembly is incorporated with an ultraviolet-curing resin. 7. The device under claim 1 in which this pre-wired assembly is further assembled with non-active fibers arranged adjacent to the optical fibers. 8. Devices under claim 1 in which this non-active fiber has the same structural design as an optical fiber. 9. Equipment under claim 8 where this non-active fiber is positioned between optical fibers. 10. Equipment under claim 8 where this optical fiber is positioned between non-active fibers. 11. An apparatus under claim 1 in which the protective sheath on both ends of this optical fiber cable is removed to expose this optical fiber. 12. The device under claim 11, to which this housing is closed at the end to the MT connector. 13. The device under claim 12 in which the second end of this optical fiber cable is terminated to an optical device. 14. The equipment pursuant to claim 13, which is selected from a group of optical devices comprising simplex fiber optic connectors, duplex fiber optic connectors, MT connectors, parallel fusion splints, mechanical splints, simplex V-slots, toggle blocks and assemblies thereof. 15. Devices under claim 1 where the wired assembly is either straight or curved.
