In the structure, the 24-core optical cable is mainly divided into two types of outdoor and indoor structures. The outdoor core is mainly of the center beam tube type and the layered type. It is generally more commonly used in the layered type because the number of cores accommodated in the layer stranded type is relatively large, and the protection performance is better than that of the center beam type. (The center beam type is a structure in which the optical fiber is located in the center of the cable, and is filled with no-paste and double-wire reinforcement. The layer twisting is a structure in which the optical fiber surrounds the center reinforcement.) The indoor type is mainly bundled. The main structure (model is GJFJV)
Optical cable model
In terms of model selection, 24-core fiber optic cables are mainly available in both outdoor and indoor models. Outdoors include GYXTW, GYTS, GYTA, and GYTA53. Indoors have GJFJV.
24-core cable model
1. GYXTW: The center beam tube type truss structure can accommodate 4-12 cores, suitable for overhead laying.
2, GYTS: layered twisted belt truss structure, can accommodate 4-144 core, suitable for buried and pipeline laying. (When buried, it is necessary to put on a layer of PVC pipe)
3, GYTA: Stranded with aluminum structure, can accommodate 4-144 cores, suitable for buried and pipeline laying. (When buried, it is necessary to put on a layer of PVC pipe)
