Loose Tube Stranded Non-Armored Flame Retardant Optical Cable with Non-Metallic Central Strength Member (GYFTZY)

GYFTZY cable is constructed by placing 250µm fibers into loose tubes made of high-modulus material; the loose tubes are filled with water-blocking compound. The center of the cable core is a glass fiber reinforced plastic (FRP), and the loose tubes (and filler rods) are stranded around the central strength member to form a compact and round cable core; the gaps in the cable core are filled with water-blocking filler. A flame-retardant jacket is extruded over the cable core to form the cable.

Product Standards

The company's GYFTZY cables comply with YD/T 1114 and IEC 60794-1 standard.

Product Features

• Excellent mechanical performance and temperature characteristics

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

• The tubes are filled with special jelly compound, providing critical protection for the fibers

• The special jacket material offers excellent flame retardancy

• Good crush resistance and flexibility

• The following measures are taken to ensure the water-blocking performance of the cable:

- Single non-metallic central strength member

- Special water-blocking compound is filled into the loose tubes

- Fully filled cable core
