Description

Access optical cable

Technical Field

The utility model relates to an optical cable technical field especially relates to an access optical cable.

Background

The access optical cable is characterized in that 250 mu m optical fiber is sleeved in a loose tube made of high modulus material, and waterproof compound is filled in the loose tube. The center of the cable core is a non-metal reinforced core (FRP), and for optical cables with certain core numbers, a layer of Polyethylene (PE) is required to be extruded outside the non-metal reinforced core. The loose sleeve (and the filling rope) is twisted around the central reinforced core into a compact and round cable core, a layer of flame-retardant inner sheath is extruded after longitudinal wrapping, and the flame-retardant sheath is extruded after the double-sided plastic-coated steel belt (PSP) is longitudinally wrapped to form a cable.

The traditional access optical cable has the defects of poor mechanical property, temperature characteristic and fire resistance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an access optical cable that has fine mechanical properties, temperature characteristic and fire resistance is provided.

For solving the technical problem, the utility model provides an access optical cable, including optic fibre, insulating fire-retardant layer, low smoke and zero halogen sheath, reinforcement, water blocking tape, plastic-coated aluminum strip, oversheath, division cable rope, its characterized in that, the parcel has insulating fire-retardant layer on the optic fibre, the optic fibre both sides are equipped with the reinforcement, in low smoke and zero halogen sheath was located to reinforcement and optic fibre, low smoke and zero halogen sheath skin parcel in proper order has water blocking tape, plastic-coated aluminum strip and oversheath, be equipped with two division hawsers between water blocking tape and the low smoke and zero halogen sheath.

Furthermore, the insulating flame-retardant layer and the low-smoke halogen-free sheath are compounded into a whole.

Further, the reinforcement is a nonmetal reinforcement, and the reinforcement is of a cylindrical structure.

Further, a waterproof compound is arranged in the water-blocking tape.

Further, the plastic-coated aluminum strip is a double-sided plastic-coated aluminum strip.

Further, the outer sheath is a PE sheath.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses fine mechanical properties has, temperature characteristic and fire resistance.
