ABSTRACT:
Apparatus for on-site connection of two transmission cables comprising optical fibres, each cable having a protective armouring enclosing a central core provided with regularly spaced grooves on its periphery. Each groove holds a fibre provided with a thin sheath of uniform thickness. After the end of one of the cables has been bared over a given length, the uncovered fibres are moved towards the exterior and secured to a holder surrounding the cable. Thereafter the core is cut perpendicularly to its axis and a grooved portion of an extension core is secured thereto; the fibres are bent back into the grooves in the said portion, and the core portion and the fibres which it bears are cut and subsequently coated with a lubricant. The same operations are performed on the end of the other cable and the two cables are clamped together under a predetermined pressure.
Various devices for on-site connection of cables with optical fibres are described.
