OPTICAL FIBER CABLE · G.652D / G.655 / G.657 · 2–576 CORES
Optical fiber cable — from duct backbones to live transmission towers.
Loose-tube stranded, centre-tube, ribbon, ADSS, OPGW, OPPC and power-fiber composite designs, manufactured against IEC 60794 with the full parameter tables from our 2026 catalogue published on each product page.
§01 — Product lines
Fiber optic cable types by installation
Duct and Direct-Buried Fiber Optic Cable (GYTA / GYTS / GYTA53)
Loose-tube stranded optical cable for duct and aerial installation (GYTA/GYTS) and direct burial (GYTA53 with double sheath and PSP armour). 24–576 cores.
Aerial Fiber Optic Cable (ADSS / OPGW / OPPC)
All-dielectric self-supporting cable to 1180 m spans; optical ground wire for 35–750 kV transmission lines; optical phase conductor for distribution lines.
Composite Power and Fiber Cable (OPLC / OPMC / GDTS)
Optical fiber composite low-voltage and medium-voltage power cables — one trench carries both power and communication for smart-grid and FTTH-in-building projects.
Mining and Specialty Optical Cable (MGTSV)
MGTSV mining flame-retardant optical cable, high-flame-retardant and fire-resistant designs, leak-monitoring and downhole temperature-sensing cables. Confirm availability per project.
