GYTS ﬁbre optic cables are constructed with 250um ﬁbre optics ﬁbres 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) wrapped longitudinally and then extruded with a polyethylene sheath.
Very good mechanical properties and temprature characteristics The loose tube material itself has good hydrolysis resistance and high strength The tube ﬁlled with a special oil paste, which provides critical protection for the optical ﬁbres Specially designed compact cable construction prevents retraction of the casing PE jacket with high resistance to UV radiation The following measures are used to ensure that the ﬁbre optic cable is watertight.
– Single steel wire central reinforcement core
– Special waterprooﬁng compounds in the loose sleeves
– Complete core ﬁlling
-Double-sided plastic coated steel belt armouring
