ABSTRACT:
Optical fibers are spliced by a technique that yields very low loss and accommodates fibers having different outer diameters or having nonconcentric cores. The technique is especially useful for single mode optical fibers, and splice losses of less than 0.1 db in a wavelength range of about 1.3 to 1.55 micrometers is typically obtained. The splice comprises a slotted tube surrounding abutted fiber ends, with the tube being at least partially filled with cement. An outer cylindrical sleeve is optionally provided for increased strength. In splicing the fibers, the fibers are aligned by means of a scattered light detector comprising a slotted tube surrounding a portion of the fiber, and a detector at one end of the tube. A sensitive null indication is obtained which provides for precise alignment of the fiber cores.
