The process of separating an optical fibre by a controlled fracture of the glass, for the purpose of obtaining a fibre end, which is flat, smooth, and perpendicular to the fibre axis.

The process of cutting an optical fiber by a controlled fracture of the glass, for the purpose of obtaining a fiber end, which is flat, smooth, and perpendicular to the fiber axis. Coating A material applied to the cladding for protective purposes.

A cleave in an optical fiber is a deliberate, controlled break, intended to create a perfectly flat endface, perpendicular to the longitudinal axis of the fiber. Since there are no crystalline planes in glass, this process is not cleavage in the crystallographic sense of the word, although the techniques used and the finished result are quite similar.
