Abstract: A cable gland for securing a cable to a box comprises a tightening element configured to surround the cable, the tightening element having at least two connecting ends mutually approachable to tighten the tightening element on the cable, and a gland body extending along an axial direction between a first end and a second end, the gland body defining a passing through channel extending along the axial direction between the first end and the second end and configured to receive the cable passing through the first and second ends, the gland body surrounding at least partially the tightening element. The cable gland comprises a first locking arrangement configured to lock along the axial direction the gland body relative to the tightening element.

Abstract: An optical fiber unit for air-blown installations includes a number of optical conductors, a first layer of resin material, a second layer of resin material radially outer to the first layer of resin material and a sheath of a thermoplastic material, wherein the second layer of resin material has a secant modulus higher than a secant modulus of the first layer of resin material and wherein the sheath of thermoplastic material is over and in close contact with the second layer of resin material.
