Abstract: An optical insulated core with a coated optical fiber (2) shows a core jacket (4) with a core jacket material containing polyvinylchloride (41) which is applied to the coating of the optical fiber. It contains a solid component (42) distributed within the core jacket material, which produces a mechanical separation effect against the coating of the optical fiber. The solid component (42) is mixed and distributed into the core jacket material during a compounding process. Thus the core jacket can be removed from the coating of the optical fiber in a simple way.

Abstract: The laser-markable sheathing comprises a carbon-blacked inner PE layer with a soot proportion of 2.5±0.5% by weight and an outer PE layer 0.05 to 0.2 mm thick. The outer PE layer completely absorbs the laser radiation (?=532 nm) used for the marking, and the inner layer beneath it remains intact. A largely carbon-free, foamlike structure which greatly scatters incident light serves as an abrasion-proof marking. The sheathing is suitable for cable cores, fiber-optic cable strands, and the like.

Abstract: A canal or pipe system and process for rehabilitation of a canal or pipe system and for installation of a cable or empty tube into a canal or pipe system as well as device for installation of a cable or empty tube. For rehabilitation of a canal or pipe system (AR) an outer casing (AL1) is inserted. Subsequently, an inner casing (IL1) with help by distancing elements (AH) is inserted, so that a ring gap (RS) between the inner and outer casings (IL1, AL1) is created. A cable (OC1) or empty tube (LR) to be installed is inserted together with the inner casing (IL1) in such a way, that the cable (OC1) or empty tube (LR) comes to rest in the ring gap (RS). For rehabilitation of the canal or pipe system, where a cable (OC1) or empty tube (LR) is already installed at an inner wall (IW), only the inner casing (IL1) will be inserted into the canal or pipe system (AR), so that the ring gap (RS) is created between the inner wall (IW) and the casing (IL1).
