The structure of GYFTC8Y optical cable is to sleeve the optical fiber into the PBT loose tube, and the loose tube is filled with waterproof compound. The center of the cable core is a non-metallic reinforced core, and the loose tube (and filler rope) is twisted around the central reinforced core to form a compact and circular cable core. The cable core and the steel wire strands are integrated into a figure-8 polyethylene sheath

Immarkar tal-għant
Il-kulur tal-immarkar huwa abjad, imma jekk ir-rimarka hija meħtieġa, l-immarkar tal-kulur abjad għandu jkun stampat ġdid f'pożizzjoni differenti.
Mhux ċar li okkażjonalment mhux ċar it-tul ta 'l-immarkar jekk iż-żewġ immarkar tal-viċin huma ċari.
Both cable ends are sealed with heat shrinkable end caps to prevent water ingress.
