Abstract
One or more optical fibers, forming part of a cable for the transmission of luminous signals, are divided into sheathed sections spliced together inside a junction box having opposite walls provided with a pair of nipples in which the incoming and outgoing cable portions are resiliently clamped. Between these nipples the two sections of each fiber, partly stripped of their sheaths, are bent into a loop along which they are joined together by a sleeve. Adjacent fiber loops of the same cable can be separated within the box by interposed sheets. The loops not only relieve stresses on the bared fiber ends but also facilitate the equalization of ray paths in a multifiber optical cable.
