Detailed introduction

· Product Description

The fibers, 250μm, are positioned in a loose tube made of high modulus material. The tubes are filled with a water-resistant filling compound. At the center of the cable core is a metal reinforcing core. For some cables with a certain number of cores, a layer of polyethylene (PE) is added to the metal reinforcing core. The loose tube (and filler) is twisted around the central reinforcement core to form a compact and round cable core. The gaps in the cable core are filled with water-blocking filler. The cable is longitudinally coated with aluminum strip (PL) and then extruded with polyethylene sheath.

· Product Features

· Excellent mechanical properties and temperature characteristics · The loose tube material itself has good water resistance and high strength · The pipe is filled with special oil to provide critical protection for the optical fiber · Specially designed tight structure of the cable · PE sheath has good uv radiation resistance. · The following measures are adopted to ensure the waterproof performance of the optical cable: - single wire center to strengthen core - pine casing fill special waterproofing compound - fully filled cable core - plastic coated aluminum (APL) with moistureproof layer, product standards

GYTA fiber optic cables comply with YD/T 901-2001 and IEC 60794-1
