The Tele-Fonika Z-XOTKtsd 144J cable features a multi-tube design – loose tubes spirally wound around a central FRP (fiber-reinforced plastic) strength member.
This model has 12 active tubes, each containing 12 single-mode fibers, giving a total of 144 fibers – hence the designation 12x12.
The use of 1.8 mm mini-tubes reduces the overall cable diameter and weight. Compared to standard 2.4 mm tubes, this cable offers a 30% smaller minimum bending radius and lower weight.
The central strength member is a dielectric FRP rod, and the cable core is protected with a dry water-blocking system. The tubes are filled with a hydrophobic gel that protects the fibers from moisture penetration.
The cable uses single-mode SM 9/125 µm fibers, type G.652D, characterized by:
very low attenuation,
minimal dispersion,
long-distance transmission capability.
These fibers are used in over 90% of modern fiber optic installations, including short-distance applications. Upon request, other types such as G.657.A2 or multimode fibers can be used.
The Z-XOTKtsd 144J cable is designed for outdoor installations. It is:
Fully dielectric – safe for installation near LV, MV, and HV power lines,
Weather-resistant – resistant to UV radiation, temperature variations, and moisture,
Water-blocked – protected against water ingress by hydrophobic gel and water-swellable tapes,
Lightweight and compact – easy to blow into microducts and telecom conduits,
Logistically efficient – lower mass and smaller diameter reduce transport costs and duct space (e.g., Orange networks).
It is most commonly installed in Ø32, Ø40, or Ø110 fiber ducts.
Due to the lack of metallic reinforcement, the cable is less resistant to high pulling forces but is ideal for air-blown installation techniques.
