Abstract
The present invention discloses a redundant optical fiber holding method for welding an optical cable, which comprises a holding disc 1, fixing holes 2 of a left optical fiber box and a right optical fiber box, a joint upper notch 3, a joint lower notch 4, a left optical cable inlet 5, a right optical cable inlet 6, an optical fiber blocking ear 7, a notch 8 for fixing an optical fiber bundle, etc. The present invention is characterized in that connected optical fiber protective joints 9 are respectively arranged in the upper notch 3 and the lower notch 4, and a twisted '8' method is adopted for holding the redundant optical fiber in the holding disc 1. The present invention has the advantages that high holding speed, no hard knots in disassembling the optical fiber, and capability of providing the sufficient remelting optical fiber.
Description
The present invention relates to a kind of holding method of optical cable welding slack, belong to the parts of optical transmission system.
The holding method of existing optical cable welding slack, " fiber optic cable communications engineering " (author: Zhang Xibin) propose in the literary composition as People's Telecon Publishing House's publication, after all fibre junctions in the optical cable are good, will accommodate fibre-optical splice and remaining remaining optical fiber (generally on the fibre-optical splice both sides each residual ten centimetres) and be fixed in the cable splice closure.Concrete holding method is as follows: general's fibre-optical splice that welding is good and remaining optical fiber thereof are looped and are fixed on the interior pallet of cable splice closure.The protective casing of fused fiber splice head will be fixed.The radius-of-curvature that remaining optical fiber is looped in fiber cable joint can not be too small (general～50mm), the order that the remaining length of optical fiber is placed in optical cable head is not noted that causes extra-stress for the fused fiber splice head.Figure 136 shows the situation that reinforcement, copper signal wire, optical fiber on the fiber cable joint inner pallet are placed.The situation that Figure 13 .6 optical fiber is placed is: the mode of accommodating of the remaining length of optical fiber (selecting from " lightguide cable link engineering "), no matter cable connection sheath, the joint case (box) of which kind of mode, a common characteristic is the collecting position with the remaining length of optical fiber, as fiber management tray, surplus fine plate, accommodation bag etc.According to the fine mode of the different dish of the sheath design of different structure.Though the optical fiber holding method is more, generally can reduce the mode of accommodating of four kinds of excess fiber lengths shown in Fig. 9 .20.Its weak point is: remaining length is few, in case fibre is torn in the inconvenience of breaking down in the fine box open, utilizes slack can not realize continuing again, causes that to rob the logical time longer, influences proper communication.
The objective of the invention is to propose that a kind of left and right sides optical fiber adopts clockwise and inhour twists into the quick holding method of " 8 " word.
The object of the present invention is achieved like this: this optical cable welding slack holding method is for putting into the fiber optic protection joint that has connected in notch up and down; its method is: optical cable from about two optical cables enter the hole and enter in the storing tray; finish continuing of two ends optical cable; for optical fiber suitable for reading; optical fiber from left and right sides optical cable advance the hole enter be twisted into about behind " 8 " word; earlier circle on the figure of eight is accommodated in the storing tray; then the fiber optic protection joint is put into notch; the right optical fiber inhour twisting; left side optical fiber right-hand lay; inside doubling is respectively accommodated in the storing tray.For end opening optical fiber, optical fiber enters the hole from left and right sides optical cable and enters, and behind the complete connection, joint is put into down notch, the right optical fiber right-hand lay, and the twisting of left side optical fiber inhour, inside doubling is respectively accommodated in the storing tray.
Advantage of the present invention: 1. when adopting connector box to carry out cable connection, because the end opening optical fiber to the right adopts right-hand lay to become the figure of eight, end opening optical fiber to the left side adopts inhour to twist into the figure of eight, adopt inhour to turn round to the optical fiber suitable for reading on the right and be hinged into the figure of eight, optical fiber suitable for reading to the left side adopts right-hand lay, so the speed of accommodating is fast.2. owing to adopt above-mentioned holding method, so can not kill knot when tearing fibre open.3. when disconnected fibre or deterioration take place optical fiber, can provide enough welding optic fibres again.
Accompanying drawing of the present invention has.
Fig. 1 upper and lower opening fiber optic protection joint placement location synoptic diagram.
Fig. 2 optical fiber holding method suitable for reading synoptic diagram.
Fig. 3 end opening optical fiber holding method synoptic diagram.
" 8 " twisting synoptic diagram about Fig. 4 optical fiber suitable for reading.
Below in conjunction with drawings and Examples the present invention is further described.
Fig. 1 is a upper and lower opening fiber optic protection joint placement location synoptic diagram.As can be seen from the figure, notch 4, left optical cable enter hole 5 under notch 3, the joint on the fine box fixed orifice 2, joint, right optical cable advances notch 8 of hole 6, fiber retaining lug 7 and fixed fiber bundle etc. about being equipped with in storing tray 1.Fiber retaining lug 7 by up and down each a pair of and about each one totally six form.They all are symmetrical arranged.
Fig. 2 is an end opening optical fiber holding method synoptic diagram.The fiber optic protection joint 9 that has connected is put into notch 4 under the joint.Optical fiber advances hole 5 and right optical cable from left optical cable and enters hole 6 and enter storing tray 1, behind the complete connection, fiber optic protection joint 9 put into down in the notch 4, and the right optical fiber right-hand lay, the twisting of left side optical fiber inhour, inside doubling is respectively accommodated in the storing tray 1.
Fig. 3 is an optical fiber holding method synoptic diagram suitable for reading.As can be seen from the figure; optical fiber advances hole 5 and right optical cable from left optical cable and portals and 6 enter storing tray 1, behind the complete connection, and " 8 " word about optical fiber is twisted into; earlier circle on the figure of eight is accommodated in the storing tray 1, then fiber optic protection joint 9 is put into notch 3 on the joint.
Fig. 4 is " 8 " twisting synoptic diagram about optical fiber suitable for reading.As can be seen from the figure, the twisting of the right optical fiber inhour, left side optical fiber right-hand lay, inside doubling is respectively accommodated in the storing tray 1.
The holding method of optical cable welding slack of the present invention is applicable to accommodating of any boxlike slack.
