GYTA is an outdoor stranded loose tube fiber optic cable with aluminum tape armor (indicated by the “A” in GYTA). It is designed for aerial and duct installations but is not recommended for direct burial. Choosing the wrong outdoor armored cable can turn a simple backbone link into a maintenance nightmare. Whether you are running a 10-km campus ring or a direct-burial path between two data halls, understanding the differences between GYTA, GYTS, and GYTA53 is the difference between a 20-year. This guide explains when armored outdoor fiber cable is needed and how to compare cable code, sheath, armor layer, water blocking and datasheet values safely. Armored outdoor fiber optic cable should be selected when the route has mechanical risk that a normal outdoor cable may not handle, such as. DYS outdoor fiber optic cables are built for harsh-environment routes — direct burial, aerial, duct and self-supporting. High strength loose tube has hydrolysis resistant.
