GYFTY
Loose Tube Stranded Non-Armored 2-144 Core Outdoor Aerial & Duct Communication Fiber Optic Cable
Structure:
The structure of GYFTY optical cable is that 250μm optical fiber is sheathed in a loose tube made of high modulus material, and the loose tube is filled with waterproof compound.
The center of the cable core is a glass fiber reinforced plastic (FRP). The loose tube (and filler rope) is twisted around the central reinforcing core to form a compact and round cable core. The gaps in the cable core are filled with water blocking fillers. A layer of polyethylene inner sheath is extruded outside the cable core to form a cable.
● Loose tube protects once coated optical fiber
● The loose tube is twisted around the reinforcement
● The reinforcement is in the center of the optical cable
Feature:
● Adopt "SZ" bidirectional layer twisting technology
● Filling water blocking ointment step by step, full section water blocking
● Steel (aluminum) belts have reliable bonding, high strength and no cracking when twisted
● Stable fiber length control
● After the cable is formed, the additional attenuation of the optical fiber is almost zero, and the dispersion value does not change
● Excellent environmental performance, applicable temperature range is -10 ℃ ~ + 70 ℃
