20100101277 | METHOD OF FUSING OPTICAL FIBERS WITHIN A SPLICE PACKAGE - The present invention relates to methods of connecting optical fibers. In a first aspect, the method proceeds by using a ferrule device having a passage adapted to apply radial pressure to optically align and hold in position opposed fiber ends, and fusing said fiber ends held by said ferrule device. In another aspect, the method of the present invention uses a ferrule device to optically align without mechanized adjustment and hold in position opposed fiber ends with a gap where said fiber ends meet, where the fibers have a temperature of fusion that is higher than a melting temperature of said ferrule device. The method then transmits radiation directly onto said fiber ends without significant direct transmission onto said ferrule device to generate heat in said fiber ends and fuse said fiber ends held by said ferrule device. | 04-29-2010 |
20100142894 | METHOD AND DEVICE FOR OPTICALLY COUPLING OPTICAL FIBRES - An optical coupler, the optical coupler being usable with a first optical fibre and a second optical fibre. The second optical fibre defines a second fibre coupling section and a second fibre transmitting section extending from the second fibre coupling section. The second fibre coupling section defines a radially outwardmost peripheral surface, the radially outwardmost peripheral surface defining a peripheral surface coupling portion. The optical coupler includes a coupler first end section and a substantially opposed coupler second end section, the coupler first end section defining a first coupling surface. The optical coupler defines a second coupling surface extending along the coupler first and second end sections. The first coupling surface is optically couplable with the first optical fibre and the second coupling surface is positionable so as to extend substantially parallel to the peripheral surface coupling portion and to be optically coupled with the peripheral surface coupling portion. The optical coupler has optical and geometrical properties such that substantially all the light guided to the first coupling surface by the first optical fibre is directed towards the second coupling surface and into the second optical fibre through the peripheral surface coupling portion so as to be guided into the second fibre coupling section for transmission into the second fibre transmitting portion. | 06-10-2010 |
