ABSTRACT:
A guide for use in making an optical signal transmissive connection between the ends of a pair of single optic fibers. The guide comprises a body having a mid-portion and a pair of end portions and defining a channel extending through said body and having open ends. The channel includes a tapered upper corner which extends longitudinally along the mid-portion of the body. The end portions of the channel extend downward at an acute angle to the mid-portion of the body so that a fiber inserted into an open end of the channel is automatically guided into the upper corner in the mid-portion of the channel. In some embodiments the guides are formed of at least three pre-determined length glass rods which are disposed in a side-by-side array parallel to one another with longitudinal peripheral portions of adjacent rods in contact with and connected to each other to form a cusp-shaped interstitial channel therebetween and with one cusp forming the corner. In another embodiment, the body is formed of a hollow tubular member whose intersecting walls form the interstitial channel with its attendant top corner. In the preferred embodiment of the guide, the mid-portion of the channel is straight while the end portions are also straight but extend downward at an acute angle to the mid-portion. A method for forming the guide is also disclosed.
