Abstract: A drop cable includes a transmission core, a strength member arranged alongside the transmission core and an outer sheath surrounding the transmission core and the strength member. The transmission core comprises two insulated conductors and an optical sub-core comprising six or more optical fibers, the optical sub-core and the insulated metallic conductors being stranded together and surrounded by a sleeve. Moreover, a diameter of the strength member is substantially equal to or higher than a diameter of the transmission core.

Abstract: An exemplary optical cable comprises a sheath surrounding a cavity and a plurality of modules arranged within the cavity with a filling ratio between 20 and 50%. Exemplary modules include four to twelve optical fibers and a tube surrounding the optical fibers. An exemplary tube has a layered structure including an inner layer of polycarbonate and an outer layer of low friction polymer, such as polyamide and/or fluorinated polymer. An exemplary tube has a ratio between its inner diameter (di) and its outer diameter (do) between 0.45 and 0.55, and its outer layer has a thickness between 0.05 and 0.15 mm. The filling ratio of the module is typically 55% or greater.

Abstract: The cable (1) includes a cable outer sheath (12) surrounding a cable core (11) and at least a ring (21, 23, 25, 28, 30) surrounding partly the cable outer sheath (12) so that the ring (21, 23, 25, 28, 30) presses the cable outer sheath (12) on the cable core (11) in a way adapted to increase a transfer, on the cable core (11), of a pulling effort exerted on the cable outer sheath (12).

Abstract: A method is proposed for access to optical fibers contained in an optical module, with a flexible structure for example, of an optical fiber transmission cable. The optical module includes a protective sheath in which the optical fibers are housed. Such a method includes: extracting the optical module from the transmission cable; degrading a portion to be stripped of the sheath of the optical module by heating to a specific temperature, for a predetermined duration; and accessing the optical fibers by stripping the portion to be stripped that has been degraded.

Abstract: Disclosed is a method accessing one or more optical fibers in a telecommunication cable in a way that considerably reduces the risk of damaging the optical fibers. To avoid inadvertent damage caused by a cutting tool, the method includes moving optical fibers and/or micromodules away from the area on the cable that is to be cut.

Abstract: An optical fiber cable (10) type comprises at least one tube (12) having optical fibers (14) housed therein. The optical fibers (14) extend helically in a longitudinal direction inside the tube (12). In the method of the invention, the tube (12) is fed to the die for manufacturing the cable (10) by unreeling the tube (12) from the storage reel (24) while the storage reel (24) is held stationary, thereby conferring longitudinal twist on the tube (12) constraining the optical fibers (14) it contains to follow a helical path of pitch substantially equal to the length of one turn of the tube (12) wound on the storage reel (24).
