Classification Of Duct Fiber Optic Cables

Duct fiber optic cables are classified based on their installation environment; specifically, they refer to cables deployed within communication conduits. The very same cable-depending on its installation method-would be classified as an aerial cable if mounted on utility poles, or as a direct-buried cable if laid directly into the ground.

Based on their intended application, stranded-loose-tube fiber optic cables can be categorized into direct-buried, duct, and aerial types. Common models for duct and aerial applications primarily include the GYTA and GYTS series.  The GYTA series encompasses various structural variants; examples include the GYTA53-which features double-layer steel tape armor suitable for direct burial-the GYFTY (a non-metallic version utilizing a non-metallic strength member to resist electromagnetic interference), and the GYTA33-a plastic-coated steel tape armored variant specifically designed for shallow-water environments.

Taking the GYTA cable as an example, its application scope is extensive, spanning the telecommunications, electric power, transportation, and petroleum industries, as well as the military sector. Furthermore, it finds application in other fields such as industrial automation and medical instrumentation.
