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

Ukumaka i-Sheath
Umbala wokumaka umhlophe, kepha uma kudingeka lokho kuphawulwa, ukumaka umbala omhlophe kuzoprintwa kusesimweni eshlukile.
Ukucaciswa ngezikhathi ezithile kokumakwa ubude kuvunyelwe uma womabili amamaki angomakhelwane ecacile.
Both cable ends are sealed with heat shrinkable end caps to prevent water ingress.
