Abstract
A wiring method for optical communication cables in building features that the optical trunk cable can be prewired by means of branch units and the number of the preserved bare lines and the number of branch cables can be freely chosen and varied according to actual conditions.
Description
The present invention relates to be used for the wiring of the fiber optic cables of buildings such as office building.
In buildings such as office building, being used for the appointment core tape line (tape core wire) of the main cable of optical fiber communication or the photocentre line (taped optical core wire) of strip winding hangs down from buildings top, and be connected on regional optical fiber cabinet (precincts-optical cabinet) PT, zone optical fiber cabinet be installed in buildings underground, be connected on the main cable from the outside of buildings, specify the photocentre line of core tape line or strip winding mechanically to be welded together, use connector to link to each other with regional optical fiber cabinet PD in being installed in designated floor.In addition, floor is connected with the network channel terminal device with the optical cable from regional optical fiber cabinet of vertical floor.
In traditional main cable in being lifted on buildings, remove the sheath of assigned address in the erecting stage, and the heart line of its strip winding is connected among the regional optical fiber cabinet PD.Therefore, must rectangular connector connect, mechanical connection or the like, shortcoming is that work is heavy and make mistakes easily.
When changes in demand (although demand not malleable) when causing that the loop is increased, must have extra wiring, it is heavy that such shortcoming is that engineering becomes.
Given this, not need to wish at the scene to carry out heavy connection work by connector connection etc., it can carry out in factory, and main cable can adopt branch's utensil wiring, and this can easily carry out at the scene.In addition, the quantity of the photocentre line of the outside of reservation wiring can freely be selected with the quantity that is used for the branch cable of floor, and when demand changed, the loop increases also can as easy as rolling off a logly finish.
It is believed that these novel characteristics are feature of the present invention, about its structure and method of operating, with and further target and advantage, reference will be made to the accompanying drawings hereinafter, the preferred embodiment wherein of the present invention illustrates as example.

With reference to accompanying drawing the preferred embodiments of the present invention are described in detail hereinafter.Can best understanding be arranged to the present invention by reference accompanying drawing 1 to 3.Fig. 1 to 3 has illustrated the wiring of the fiber optic cables that are used for buildings of first embodiment of the invention.
A plurality of branch cables 12 of floor use branch's utensils 9 to be divided into the floor photocentre line in each floor part or required floor part or the photocentre line 4 of strip winding main cable 8, and are connected to the fiber cabling case 10 of each floor at connector 11.
The outside wiring 13 of a plurality of reservations comprises the photocentre line 4B of photocentre line or strip winding, its lower end is through being formed on the through hole 3 of each floor slab surfaces and connecting up in buildings 2 bottoms, and its upper end is connected by connector 11 respectively with the upper end of the reservation photocentre line of main cable 8 or the photocentre line 4A of strip winding.
A plurality of link 14 corresponding outside wirings 13 place each layer.
Wiring 1 at the fiber optic cables that are used for the said structure buildings, the photocentre line of the lower end of main cable 8 or the photocentre line 4 of strip winding and 4A are connected on the terminal block (not shown) with connector, terminal block is connected on the external circuit, and the photocentre line of outside wiring 13 bottoms or the photocentre line 4B of strip winding connect with connector 11.
Under the situation that demand changes, only need be by connecting up on the connector component 14 that the branch cable (not shown) is connected to outside wiring 13 parts.
Be described referring now to 4 to 20 pairs of other embodiments of the invention of accompanying drawing.In the accompanying drawing of whole embodiment, same parts is represented by the Reference numeral identical with first embodiment, and is no longer further elaborated.
The second embodiment of the present invention is shown in Fig. 4 to 6.The difference of itself and first embodiment is: the link 14 of connector and 14 places respectively in each floor between the heart line 4B of half photocentre line or strip winding, thereby it can become outside wiring 13 of the reservation of different floors.Therefore, the wiring 1A of the fiber optic cables of buildings finishes, and half can be reduced in the coupling part 14 of the connector of feasible outside wiring 13.
The third embodiment of the present invention is shown in Fig. 7 and 8.Its difference with first embodiment is: adopted floor main cable 8 and reserved combining of main cable 8A.Wiring 1B according to this mode of the 3rd embodiment has identical advantage with first embodiment.
The fourth embodiment of the present invention is shown in Fig. 9 and 10.The difference of itself and first embodiment is: the another kind of photocentre line of photocentre line 4 usefulness of a plurality of photocentre lines or strip winding or the photocentre line 4C of strip winding replace.The photocentre line 4C of photocentre line or strip winding is used for floor or reservation, it is routed to: by its end is placed in the low floor by the hole 3 that is formed on each floor slab surfaces respectively, its approximate centre part is positioned near the lifting utensil 7 on the top that is arranged on buildings by joint utensil 6.Connector link 14 places in each floor respectively between the photocentre line 4C of photocentre line or strip winding.In addition, branch cable 12 is connected with connector coupling part 14 in required floor or each floor.According to this mode of the 3rd embodiment, wiring 1C has identical advantage with first embodiment.
