Underwater Cable — ZTT fiber optic product

Underwater Cable

Steel-wire armored optical cable for submarine, river, lake and inland water crossings, up to 216 fibers. Withstands pressure, water ingress and mechanical stress; also suitable for direct burial.

Ribbon Cable — ZTT fiber optic product

Ribbon Cable

High-fiber-count design grouping fibers into ribbons for mass fusion splicing, up to 1152 fibers. Ideal for data center interconnect and hyperscale backbone deployments.

All Dry Cable — ZTT fiber optic product

All Dry Cable

Fully dry-core optical cable using water-blocking tapes and yarns instead of filling gel. Speeds up cable preparation and splicing while maintaining full moisture protection.

Color Stripe Cable — ZTT fiber optic product

Color Stripe Cable

Optical cable with a color-striped sheath for visual identification of routes or operators. UV-resistant stripes support asset management in shared or multi-operator infrastructure.

3-Strand Light Short Span Aerial Cable — ZTT fiber optic product

3-Strand Light Short Span Aerial Cable

Compact aerial cable with two FRP strength members for short-span pole-to-pole runs. Low weight and low cost make it ideal for secondary aerial and duct installations; more than 5000 km supplied to Brazil.

Easy Branch Figure-8 Self-supporting Aerial Cable — ZTT fiber optic product

Easy Branch Figure-8 Self-supporting Aerial Cable

Figure-8 aerial cable engineered for simplified mid-span branching, with one fiber per tube for fast deployment. More than 25 000 km supplied to Indonesia.

Lightning Protective Light Cable — ZTT fiber optic product

Lightning Protective Light Cable

Lightweight all-dielectric optical cable eliminating lightning hazards. Prevents bird pecking and rodent damage; well suited to short-span aerial and duct installation.

Flexible Loose Tube Cable — ZTT fiber optic product

Flexible Loose Tube Cable

Loose-tube optical cable whose flexible tubes can be stored in joint boxes instead of individual fibers, reducing splice and installation time. Minimum bending radius ≤ 3× tube OD.

FTTx Cable — ZTT fiber optic product

FTTx Cable

Round, ribbon, spiral-steel-wire armored and flat drop cables purpose-built for fiber-to-the-x access networks. Bend-insensitive fiber and PVC/LSZH sheath for indoor and outdoor last-mile deployments.

Flame-retardant Cable and Fire-resistance Cable — ZTT fiber optic product

Flame-retardant Cable and Fire-resistance Cable

Indoor optical cables compliant with flame-retardant and fire-resistance standards. Deployed at the National Stadium (Bird's Nest) and other critical infrastructure with strict fire-safety requirements.

Micro Bundle Cable — ZTT fiber optic product

Micro Bundle Cable

High-density cable family bundling 12- or 6-fiber micro modules accessible without tools. Available in Duct (DiC), ADSS (FASA), Indoor Riser and Outdoor/Indoor drop variants covering the full network.

Low Friction Drop Cable — ZTT fiber optic product

Low Friction Drop Cable

Drop cable with a low-friction outer sheath for fast pulling and blowing installation, reducing labor time on last-mile connections. Colored fiber with steel-wire reinforcement for good mechanical performance.

Invisible Drop Cable — ZTT fiber optic product

Invisible Drop Cable

Ultra-slim drop cable designed to be almost undetectable to the casual observer. Adhesive back allows fast attachment against the wall for aesthetic FTTH installations, without damaging large wall surfaces on removal.

Anti-rodent or Anti-termite Cable — ZTT fiber optic product

Anti-rodent or Anti-termite Cable

Optical cable with mechanical and chemical protection against rodents and termites, up to 624 fibers. Glass yarns, flat/round FRP armor and nylon sheath ensure long-term reliability of buried and outdoor infrastructure.

Sewer Cable — ZTT fiber optic product

Sewer Cable

Ruggedized stainless-steel-tube optical cable engineered for installation inside sewer and drainage infrastructure. Excellent corrosion, rodent and insect resistance, up to 96 fibers.

Pavement Cable — ZTT fiber optic product

Pavement Cable

Micro-trench stainless steel tube cable for shallow installation directly under pavement or road surfaces. Provides high crush resistance for concrete road embedding with minimal civil works.

Detection Cable — ZTT fiber optic product

Detection Cable

Optical cable engineered for distributed sensing — stress, temperature and pressure monitoring on dams, bridges, buildings, oil wells, coal mines, power plants and transmission lines. High-pressure and radiation resistant for hazardous environments.
