Stranded loose tube fiber optic cable with APL (aluminum-polyethylene laminated tape) moisture barrier, metallic central strength member (steel wire), and PE sheath for outdoor trunk, metro, and backbone networks.
GYTA is a stranded loose tube outdoor fiber optic cable with an aluminum-polyethylene laminate (APL) moisture barrier, designed for duct, conduit, campus backbone, and metro access network installations. The stranded loose tube design around a central strength member supports configurable fiber counts, while the APL barrier provides radial moisture protection for outdoor environments.
