Abstract: An optical-fibre connector comprises a support piece 1, a first locking piece 2 and a second locking piece 3. Locking pieces 2 and 3 are respectively fixed to the support piece 1by screws 4 and 5 which are engaged in cylindrical bores containing sleeve of elastomer material. The locking piece 2 comprises at its base two bearings 8 and 9. To connect two series of optical fibres, two identical connectors are disposed end to end and connected by two spindles 10 comprising a threading 11 which engages in a metallic sleeve 12 containing a sleeve 13, made of an elastomer material. This assembly permits absorption of vibrations and limitation of the clamping in order to avoid breaking of the optical fibre during use or connection of the two series of optical fibres.

Abstract: A cable for telephone or other communication circuits comprises a number of conductor arrays, specifically pairs or quads of helically intertwined conductors, each conductor having a metal core coated with a thermoplastic sheath in which a multiplicity of short cellulose fibers are embedded; the fibers have an average length of about 1 mm and project generally radially from the sheath over the greater part of their length. The fibers of the twisted wires interpenetrate and form a mat in the intervening spaces which swells in the event of water penetration through a defective envelope, thereby limiting the propagation of moisture along the cable.
