When a glass fiber cable emerging from a main channel (1) is guided into a domestic channel line (2), in order to prevent this glass fiber cable from unacceptably having an excessively small radius of curvature in the direction-changing area (6), and thus being damaged, and in order to ensure that the glass fiber cable (3) is in the correct position, this glass fiber cable (3) is guided in a rigid guide tube (7) whose longitudinal axis runs essentially along a cylindrical envelope surface in its central section (7′″). The rigid guide tube (7) is fixed in a pipe connecting stub (10) which can be widened elastically and thus, after insertion into the domestic channel line (2), rests on the wall thereof in a stressed manner, and is fixed in its position. That end of the guide tube (7) which projects into the domestic channel line (2) is connected via a sleeve (8) to a flexible pipe, tube (5) or the like. The glass fiber cable is passed from a switching box (4) via the rigid guide tube (7) and the flexible tube (5) to a building which is located on a piece of land and is connected to the domestic channel line (2).
A cable guide for a cable, in particular a glass fiber cable (3), which is guided in a channel system, preferably a sewage channel system, having a guide tube (7) or the like which holds the cable (3) in the area (6) of a channel mouth (2), characterized in that the guide tube (7) is rigid, with its longitudinal axis being arranged at least in the central section (7′″) along the envelope surface of a cylinder, whose axis runs in the longitudinal direction of the channel mouth (2), and in that a flexible guide element (5) such as a flexible tube, a flexible pipe or the like, which holds the cable (3) and is connected to an end area (7″) of the guide tube is provided in the channel mouth (2).
A method for producing a cable guide for a cable, in particular a glass fiber cable (3), which is guided in a channel system, preferably a sewage channel system (1), in the direction-changing area (6) on a channel mouth (2), characterized in that a flexible guide element (5), such as a flexible pipe, a flexible tube or the like, which originates from the direction-changing area (6) is first of all inserted into the channel mouth (2), in that the end of this guide element (5) is connected to a rigid guide tube (7) which has been deformed such that its longitudinal axis in the central section (7″) runs essentially along an imaginary cylindrical surface, in that this rigid guide tube (7) then is fixed on the inside of a pipe connecting stub (10) which can be widened elastically, after which the pipe connecting stub (10) is then inserted, with the rigid guide tube (7) fixed to it, into the channel mouth (2) from the direction-changing area (6) such that the pipe connecting stub (10) rests in a stressed manner on the wall of the channel mouth (2) and the rigid guide tube (7) emerges from the pipe connecting stub (10) into the channel system (1) approximately tangentially in the area of the upper boundary of this pipe connecting stub (10), following which the cable (3) is drawn into the guide tube (7) and its guide element (5) which is connected to it.
