Indoor bundled flexible fiber optic cable 12 core indoor fiber optic cable bundled fiber optic cable

Description :

　　12 core indoor optical cable is an indoor wiring cable with 12 built-in optical fibers (composed of silica and quartz glass). It has multiple structural models and two transmission modes, and is widely used in indoor cabling and backbone communication transmission through communication optical cables.

　　transmission

　　In terms of transmission, 12 core indoor optical cables are mainly available in two specifications: single-mode and multi-mode. Single mode (inner diameter of 9 μ m and outer diameter of 125 μ m) multimode (there are two types, namely inner diameter of 62.5 μ m and outer diameter of 125 μ m, and inner diameter of 50 μ m and outer diameter of 125 μ m), single mode is a long-distance transmission mode with wavelengths of 1310 and 1550; Multimode is a short distance transmission mode (limited to a transmission distance of up to 2000 meters), with wavelengths of 850 and 1300. (Single mode is widely used now, while multimode is gradually being phased out)

　　structure

　　In terms of structure, 12 core indoor optical cables are mainly divided into two types: medium core bundle tube type and layer twisted type. Mid core bundle tube type is a structure in which optical fibers are located in the core of the optical cable and reinforced with double steel wires without paste filling, capable of accommodating 4-12 core optical fibers; Layer twisting is a structure in which optical fibers are wrapped around a core reinforcement, capable of accommodating fibers with 4-144 cores.

　　model

　　In terms of model selection, 12 core indoor optical cables are mainly available in two specifications: medium core bundle tube type and layer twisted type. The medium core bundle tube type includes GYXTW, GYXTY, and ADSS; There are GYTA, GYTS, GYTA53, and GYFTY types of twisted layers.
