How to choose the number of cable cores

FIber optic Cable has a small size, light weight, transmission distance, capacity, signal attenuation, electromagnetic interference, etc., have been widely used in various networks.

Selected according to the number of different types of core cable structure can be divided into stranded type, frame type, ribbon type and the center beam tube so few, not the same structure for different purposes, the user can submit the corresponding requirements under the line. General adoption of the following 12 core center beam tube, the center beam tube process simple and low cost in overhead pipe laying or have a good network of branch lines to protect the competitive; layer stranded fiber optic cable strand or single-use center placed wire to strengthen the root, with SZ continued synthetic cable, fiber cabling up to 144 the number of cores. Its biggest advantage is waterproof, strong lateral pressure, anti-strong rally. Can be used for direct buried. At the same time easy-to-fork, some fiber-optic cable that used to be, respectively, without breaking the entire cable, just need the fiber breaking bifurcation can, which for the data communications network. Additional optical node along the cable TV network is beneficial; ribbon cable cores can do thousands of cores, it is 4 to 12 fiber arranged in rows to form ribbon fiber unit, then a certain number of ribbon units means arranged in cable, fiber optic cable is generally used in our network-level beam tube and two kinds of layers can be added.
