Abstract
The utility model relates to a parallel branch optical cable, which belongs to the technical field of optical cables. Branch optical cables are composed of single-core or a multi-core tight tube optical fibers or loose tube optical fibers, reinforcing elements and outer protective layers; connecting bands between the outer protective layers of the branch optical cables connect the parallelly placed branch optical cables together; the connecting bands between adjacent branch optical cables are longitudinally slit with at least one discontinuity incision which is convenient for separation. The utility model has the advantages of reasonable and simple structure, easy manufacture and production, beautiful appearance, good quality of products, accurate information transmission and stable performance. When the optical cable needs to be branched in the way of laying, nothing remains but to tear the discontinuity branch incision on the connecting bands between adjacent branch optical cables, the optical cable can be divided into desired number. The utility model can increase the quality of optical cable laying and engineering construction, can ensure the accuracy and stability of optical cable information transmission, and can be used in the field of optical communication.
Description
Technical field
The utility model relates to a kind of in the optical communication network and is used for the branched cable of the information of transmitting, and is easy to branch when especially laying and can be divided into the cable configuration of two or more branches, belongs to the optical cable technology field.
Background technology
The existing optical cable that is applied in the optical communication network is to be made of cable core and sheath that the mode that single core or multicore loose tube fiber pipe twist with SZ strand or spiral is twisted into.When this kind optical cable needs branch in laying, optical cable must be cut off by the connection of optical cable connecting box.This bifurcation approach will be cut off optical cable, and will handle and connect the optical fiber in the optical cable, except the cost time, influence work efficiency, and joint length in the time of also will reserving fiber cable laying more can increase sending allowance and generation fault because of fibre-optical splice.
Summary of the invention
The purpose of this utility model is to provide a kind of branch easy to connect, increases work efficiency, and avoids cutting off the parallel units of branched optical fiber cable of optical cable.
The purpose of this utility model is to realize by the improvement to existing optical cable, parallel units of branched optical fiber cable, comprise the connecting band between sub-optical cable and sub-optical cable outer jacket, it is characterized in that the connecting band between described sub-optical cable outer jacket links together the sub-optical cable of parallel placement, the connecting band place between adjacent sub-optical cable has at least is convenient to the discontinuity otch that separates together.Described sub-optical cable is made up of tight tube fiber or loose tube fiber, reinforcement and the outer jacket of single core or multicore, is to place in the outer jacket in a parallel manner.Connecting band between described sub-optical cable outer jacket and sub-optical cable outer jacket form same integral body adding man-hour simultaneously, vertically cut to be convenient to the discontinuity otch that separates at least together on connecting band.
The utility model is rational in infrastructure simple, manufactures easily, and good looking appearance, good product quality, information transmission is accurate, stable performance.When in the fiber cable laying way, needing branch, as long as tear the discontinuity branched slits of junction of the adjacent turn of outer jacket, optical cable can be divided into required radical, need not cut off optical cable integral body, reduce workload, reduce labour intensity, increase work efficiency, reduce the damage of optical cable integral body, avoid increasing sending allowance and issuable trouble spot because of fibre-optical splice, improve fiber cable laying and engineering construction quality, guarantee the accuracy and the stability of optical cable information transmission, can be widely used in optical communication field.
