ABSTRACT:
For the splicing of trunks of optical fibers, confronting trunk ends are closely juxtaposed in a surrounding enclosure which is subjected to vibrations transverse to its axis to generate an oscillating air column setting the trunk ends in vibration, the fiber trunks being clamped at points spaced from these ends by a distance sufficient to give rise to several standing-wave nodes at the applied frequency on the free fiber extremities. With these extremities vibrating in unison but at limited amplitudes compatible with the maximum permissible offset of the trunk axes, the confronting trunk ends are joined by the hardening of a blob of cement matching their refractive index, by electric fusion, or with the aid of a laser beam.
