Embodiment Construction

[0014] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] The first example is figure 1 , 3 As shown, for the access of the shaft corridor 2, a skeleton optical fiber ribbon cable 5 with 3 to 9 ribbon slots is used, and a skeleton optical fiber ribbon with 3, 5, 6 or 8 ribbon slots is commonly used For optical cables, the skeleton type optical fiber ribbon cable has a branch window 3 on each layer. The axial length of the branch window is 40-70mm, that is, the outer sheath of the cable is stripped for 40-70mm to form a branch window. Draw out the branched optical fiber ribbon 8 from the forward extension section, that is, each branching window cuts off the optical fiber ribbon that needs to be branched through the preceding branching window that extends forward, and draws a length of optical fiber ribbon from the branching window as a continuous branching Optical fiber, the optical brazing ribbon in th...

Abstract

The method of distributing fibers to doors adopts skeletal flat optical cable with branching windows connected to optical cable joint box for withdrawing branching fiber band and converting into tail fiber to door. The cable core in the skeletal flat optical cable has no filled ointment for easy to construction, the skeletal flat optical cable can hold more fibers, and each optical cable may have several branching windows in different axial positions. The present invention has greatly reduced cable consumption, easy construction and low cost, and is favorable to distributing fibers to doors.

Description

technical field [0001] The invention relates to a method for laying and distributing optical cables for fiber-to-the-home optical cables by adopting a skeleton type optical fiber ribbon optical cable. Background technique [0002] With the rapid development of communication technology and industry, optical fiber transmission has gradually expanded from medium and long-distance transmission to short-distance fiber-to-the-home. Most of the existing fiber-to-the-home optical cable laying and fiber distribution methods use tight-buffered optical cables and ordinary loose-tube stranded optical cables. When it is necessary to diverge the incoming optical fibers, it is impossible to create a separation window, so the optical cables can only be cut for splicing or laying and connecting multiple fibers at the same time. Optical cable, not only the design is complicated, the consumption of optical cable is large, the pipeline space occupied when laying is large, and a large number of ...
