The GYFTY fibre optic cable is constructed with a 250µm fibre optic cable in a high modulus material pine tube filled with a waterproof compound. At the centre of the core is a glass fibre reinforced plastic (FRP) and the loose tube (and filler rope) is twisted around the central reinforcement to form a compact and round core with a water barrier filler in the gaps. A polyethylene sheath is extruded over the core to form the cable.

Product Description

Product characteristics:

• Very good mechanical and temperature properties

• good hydrolysis resistance and high strength of the loose tube material itself

• The tube is filled with a special oil paste, which provides critical protection for the optical fibres

• Good resistance to compression and flexibility

• The following measures are used to ensure that the fibre optic cable is watertight.

- Single non-metallic central reinforcement core

- Special waterproofing compounds in the loose sleeves

- Complete core filling

Product applications and laying methods:

1. Outdoor communication system wiring

2. Pipelines, overheads, cable trenches
