PURPOSE:To improve the space utilization efficiency, to improve the flexibility of wiring, and to suppress the repeated work, by constituting the titled system so that plural fibers and plural optical fiber cables can be laid in the same perforated pipe. CONSTITUTION:Plural terminating boxes 4 are connected by a perforated pipe 5 having plural small holes in the lengthwise direction, a cable 2 is placed in the hole, and a fiber 1 contained in the cable 2 is connected to other fiber 1 and connected to a terminal equipment as necessary in the terminating box 4, or connected to the fiber 1 contained in other cable 2. The cable 2 whose connection to a terminal side is not required in the terminating box 4, and which communicates with other terminating box 4 is not cut nor terminated, and contained in the terminating box 4 in a straight drawn state. By containing plural fibers or cables in the same perforated pipe, a space in the piping is utilized effectively, and also, the flexibility and the profitability of wiring can be improved. |
