24B1.3 Span 200M PE HDPE GYFTY83 Fiber Optic Armoured Cable
GYFTY83 fiber optic cable, place six 250um optical fibers in a loose tube filled with water. 4 such tubes and 1 filler are twisted around a central strength member made of FRP (Fiber Reinforced Plastic) into a compact round cable core. Water blocking yarns are also used in the twisting process. Then, the core wire will be wrapped with water blocking tape, which together with the water blocking yarn protects the cable from water ingress. Squeeze the inner PE sheath out of the water-blocking tape, and place two tear cords (optional) under the inner sheath. Then, wrap a layer of aramid yarn on the inner sheath, and then use PE sheath to complete the cable. Next, the designed 19 FRP are precisely arranged, and then the final layer of protection is completed with a DHPE sheath.

1 Optical Cable Application:
a. The entire optical cable is made of non-metallic materials, will not conduct electricity, has lightning protection, and can be used in overhead.
b. The manufacturing process of FRP + aramid fiber makes the optical cable have a good tensile capacity, which can be used in the construction c. nvironment of the optical cable with an overhead span of 200 meters.
d. The optical cable is effective against side pressure and can be used in the construction of 30~80CM underground direct buried optical cable.
e. Can be used for laying directly under water.
f. FRP material has a certain Prevent Bird Pecking.
g. FRP material has certain anti-mouse bite.
