The GYTA53 fibre optic cable is constructed by placing a 250µm fibre optic cable in a high modulus material pine tube, which is filled with a waterproof compound. At the centre of the core is a metal reinforcement core, which for some cores is also extruded with a layer of polyethylene (PE). The loose sleeving (and filler rope) is twisted around the central reinforcement to form a compact and rounded core with gaps filled with a water-blocking filler. Plastic coated aluminium tape (APL) is wrapped longitudinally and then extruded with a layer of polyethylene.

Product Description

Product characteristics:

• Very good mechanical properties and temperature characteristics

• The loose tube material itself has good hydrolysis resistance and high strength

• Tube filled with special oil paste for critical protection of the fibres

• Good resistance to compression and flexibility

• The following measures are used to ensure the water resistance of the fibre optic cable:

- Single metal central reinforcement core

- Loose sleeves filled with special waterproofing compounds

- Complete core filling

- Plastic-coated aluminium tape (APL) with a moisture barrier

- Plastic coated steel tape (PSP) on both sides to improve the cable's resistance to moisture

- Good water barrier material prevents longitudinal water penetration
