    • This invention relates to a cable system, especially an optical fibre cable system being installed in a sewer tube system having a main sewer 1 and at least one lateral 2, entering the main sewer 1 at an entering point 4 and connecting a cable access point 5 to the main sewer 1 and a method for laying cable resulting in the cable system. The cable system is having at least one cable distributor point 6, located in or outside at or nearby a main sewer manhole 3 of the main sewer 1, and at least one main cable 7 being laid in the main sewer 1, reaching to the cable distributor point 6 and at least one access cable 8 being laid in the lateral 2, wherein said access cable 8 is connecting the access point 5 directly with the distributor point 6, being partially laid in the main sewer 1, parallel to the main cable 7, preferably wherein the access cable 8 and the main cable 7 are connected at the distributor point 6.
    • 本发明涉及一种电缆系统,特别是一种光缆系统,该系统安装在具有主下水道1和至少一个横向2的下水管系统中,在进入点4处进入主下水道1并连接电缆接入点5 到主下水道1和用于铺设电缆的方法,从而产生电缆系统。 电缆系统具有至少一个电缆分配器点6,位于主下水道1的主污水井3中或附近,以及至少一个主电缆7,其被放置在主下水道1中,到达电缆 分配器点6和至少一个进入电缆8放置在横向2中,其中所述接入电缆8将接入点5直接连接到与主电缆7平行的部分地放置在主下水道1中的分配器点6 优选地,其中接入电缆8和主电缆7在分配器点6处连接

    • An optical fiber sensor cable (2) for detecting fluids comprises a PCS fiber (3) passing through a housing (4) made of rigid material for increasing the mechanical stability of the PCS fiber (3), wherein the housing (4) is provided with at least one aperture (5) allowing fluid to pass through the housing (4) and to diffuse into the plastic cladding of the PCS fiber (3), causing a local attenuation of light transmitted by the PCS fiber (3) which is indicative of the presence of fluid. Such an optical fiber sensor cable (2) may be used in harsh environments in particular for the detection of liquids containing carbon hydroxyl groups.
    • 该传感器具有由外壳(4)部分包围的塑料包覆的二氧化硅纤维(3),以提高纤维的机械稳定性。 壳体具有孔(5),以允许流体进入壳体内的纤维并将流体扩散到纤维的包层中。 检测单元(7)由于流体扩散到包层中,检测光纤中指示流体存在的光的衰减。 还包括用于通过光纤传感器检测流体的方法的独立权利要求。
