On the whole, the cost of using ribbon fiber optic cable in the optical communication network is slightly lower than that of using ordinary optical cable. And the greater the fiber count of the ribbon fiber, the more obvious this advantage. When the fiber count of the fiber optic cable is less than 144 cores, the outer diameter of the ribbon fiber optic cable is larger than that of the ordinary optical fiber cable.īecause of the high splicing efficiency of the ribbon fiber optic cable, the splicing cost of each joint is lower. Since the optical fiber ribbon cannot be accurately aligned during the splicing of the optical fiber ribbon, the splicing attenuation is greater than that of a single core. However, when the ribbon fiber optic cable is spliced with discrete optical fibers, or optical fiber ribbons with different fiber counts, the optical fiber ribbon needs to be torn apart into individual optical fibre for splicing, which is more troublesome than the splicing of ordinary optical cables.
Although the current maximum is 576 cores, ribbon fiber cables with more than 576 cores will be used in large numbers in the future. While the number of cores of ribbon fiber optic cables is mainly affected by demand. Ordinary fiber optic cable is limited by the connection efficiency, the fiber count is generally not very large, and the maximum fiber count usually does not exceed 288 cores. At the same time, the quality of the connection will be worse too. The more the number of cores in each optical fiber ribbon, the higher the efficiency of the connection. Thereby it greatly improves the efficiency of optical fibre splicing. When the ribbon fiber optic cable is spliced by a ribbon optical fiber fusion splicer, the optical fibers of one ribbon fiber cable can be spliced at one time. Ribbon Fiber Features High Splicing Efficiency In fact, the layer stranded optical cable can also be made into dry or semi-dry water resistance structure.
However some carrier recommend it for it is a dry structure. This skeleton structural characteristics determine its strong rigidity and it is difficult to bend during construction. The skeleton ribbon fiber cable is suitable for vertical wiring in buildings for each floors to cut out and splicing. The optical fiber ribbon in the cable is generally 4 core or 6 core, which is a water-blocking dry structure, which means no grease in the cable. It’s currently the most used structure type of ribbon fiber optic cable. The optical fiber ribbon in the cable mainly has 12 cores, 6 cores, and 4 cores. The structure of the stranded optical fiber ribbon cable is basically the same as that of the ordinary layer stranded loose tube fiber cable. Ribbon fiber optic cable can be divided into layer stranded type, skeleton type and central tube type in terms of cable structure.
