Z-XOTKtsdDb Fibre Optic Cable – Durable, Dielectric and Rodent-Resistant

The Z-XOTKtsdDb fibre optic cable is a modern and reliable solution designed for the construction of outdoor telecommunications networks – long-haul, wide-area and local networks. Thanks to its fully dielectric construction, it can be installed near medium- and high-voltage power lines without the risk of electromagnetic interference. It is perfectly suited for installation in primary and secondary cable ducts, particularly in locations exposed to rodent attacks.

Properties and Applications

The Z-XOTKtsd 12F (1x12)/1.8 cable is designed for outdoor installations, particularly:

• in Ø32 and Ø40 fibre optic ducts,

• in Ø110 primary cable ducts using the cable-blowing method,

• in locations requiring a fully dielectric cable – installation near LV, MV and HV power lines is possible.

The cable features:

• resistance to UV radiation, moisture and temperature fluctuations,

• a dry water-blocking system and hydrophobic gel inside the tube,

• a small diameter and low weight – facilitating transport and installation,

• excellent suitability for cable-blowing technology,

• sequential metre marking and custom cable marking options.

Z-XOTKtsd Cable Construction a: central strength member – dielectric FRP rod, with or without a polyethylene coating b: loose tube – a loose tube containing optical fibres and filled with hydrophobic gel c: optical fibre – single-mode fibre (J), dispersion-shifted single-mode fibre (Jn), multimode fibre (G/50) or multimode fibre (G/62.5) d: filler element – polyethylene filler element e: cable core – the cable core consists of all tubes and filler elements stranded around the central strength member; the core consists of 6, 8, 12, 18 or 24 elements f: core water blocking – dry g: reinforcement – glass fibres surrounding the cable core h: ripcord – 2 ripcords for opening the cable sheath i: sheath – black HDPE outer sheath

Z-XOTKtsdDb Cable Construction

• Central strength member: dielectric FRP rod, with or without a polyethylene coating
• Optical fibres: single-mode (J), dispersion-shifted single-mode (Jn) and multimode fibres (G/50, G/62.5)
• Fibre optic tubes: loose tubes filled with hydrophobic gel, protecting the fibres against moisture
• Filler elements: made of polyethylene
• Cable core: tubes and filler elements stranded around the central strength member, comprising 6, 8, 12, 18 or 24 elements
• Core water blocking: dry
• Reinforcement: glass-fibre yarn increasing mechanical strength and protecting the cable against rodents
• Ripcords: 2 ripcords facilitating removal of the outer sheath
• Outer sheath: black polyethylene sheath made of HDPE, resistant to UV radiation, abrasion and environmental stress cracking

Key Features and Benefits

• Rodent resistance – the glass-fibre yarn reinforcement effectively protects the cable against mechanical damage caused by rodents.
• Fully dielectric construction – the absence of metal components allows the cable to be installed near power lines.
• High mechanical strength – the glass-fibre reinforcement increases the cable’s tensile strength by almost three times compared with non-reinforced cables.
• Environmental resistance – the HDPE sheath provides resistance to UV radiation, moisture, environmental stress cracking and abrasion.
• Protection against water penetration – the dry water-blocking system and thixotropic gel effectively prevent longitudinal moisture penetration.
• Versatile application – ideal for installation in cable ducts, cable pipelines and outdoor environments.
• Marking and identification – durable sequential metre marking and the option to customise the cable markings according to customer requirements.
