| Number | Title | Issue Date |
| 5195151 | Optical fiber couplers and methods of their manufacture Fiber optic couplers formed of at least two single mode optical fibers, at least one of which is an input fiber, are shown, the fibers constructed and arranged in the manner that coupling between the input fiber and the other fibers limits antisymmetric m... | 03/16/1993 |
| 5184433 | Fiber optic polisher A method and apparatus of polishing the end of an optical fiber that produces relative lateral movement between the end of the fiber and an abrasive surface while changing the angle of attack of the relative movement at a rate greater than about 10,000 ar... | 02/09/1993 |
| 5166994 | Low cost one by eight singlemode optical fiber coupler A means of fabricating wideband 1×8 singlemode fiber optic couplers is disclosed. It has been found that a 1×7 fiber optic coupler can be fused by twisting six fibers around a central seventh fiber, heating the region on contact among the seven fibers, ... | 11/24/1992 |
| 5138676 | Miniature fiberoptic bend device and method Bends in optical fibers can be miniaturized by reducing the diameter of a section of the fiber in the region where bending is desired to a condition in which the optical properties of the fiber have reduced bend-loss sensitivity. In one aspect of the inve... | 08/11/1992 |
| 5121452 | Fiber optic power splitter Fiber optic power splitters having a central fiber and a selected number of surrounding fibers spaced periodically around the central fiber and the method of fabricating such splitters are described. For splitters having between three and five surrounding... | 06/09/1992 |
| 5067787 | Electro-optical converter An electro-optical converter has at least three optical or electrical ports at least one of which is optical and one of which is electrical. The converter includes an essentially rigid support, a fiber-optic lateral coupler secured to the support includin... | 11/26/1991 |
| 5058983 | Fiber optic connector terminator A terminator for use with an optical fiber access port structure that supports an optical fiber having an optical end face exposed to communicate with a like end face of another fiber, the terminator comprising a pig-tail-free compact supporting body carr... | 10/22/1991 |
| 4997247 | Fiber optic coupler and method for making same A fiber optic coupler has at least two optical fibers each having a core with a cladding material disposed thereabout. The fibers, in a limited length coupling region, have the cladding material removed and the core exposed, the thickness of the cladding ... | 03/05/1991 |
| 4997248 | Wide band coupler A wideband single-mode fiber optic coupler and method for the fabrication of the same is provided wherein at least two fibers are joined in a fused and tapered coupling region. The taper is asymmetrical in the longitudinal extent about the midpoint of the... | 03/05/1991 |
| 4948222 | Optical fiber unit assembly package An optical fiber unit assembly package consists of a protective body having a lid and defining a volume, an entry for an optical fiber cable penetrating the body, at least one optical fiber cable extending through the entry and defining a conduit for an o... | 08/14/1990 |
| 4923268 | Fiber optic coupler A fiber optic coupler and method for forming such coupler is shown in which the substance of the fibers is preselected to have a heat fusing temperature in a range achievable by exterior heating of a shrink sleeve, and the fibers are heat fused together a... | 05/08/1990 |
| 4844573 | Electro-optical converter including ridgid support for optical fiber coupler, telephone set using the coupler and method of making same An electro-optical converter has at least three optical or electrical ports at least one of which is optical and one of which is electrical. The converter includes an essentially rigid support, a fiber-optic lateral coupler secured to the support includin... | 07/04/1989 |
