Outdoor Communication Large-Core Structure Directly Buried Anti-Ant Double Armoured Fiber Optical Cable


Constructure:

The structure of GYTA53 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 metal reinforced core. For some optical fiber cables, a layer of polyethylene (PE) needs to be extruded outside the metal reinforced core. The loose tube (and filler rope) is twisted around the central reinforcing core to form a compact and round cable core, and the gaps in the cable core are filled with water blocking fillers. Plastic coated aluminum tape (APL) is longitudinally wrapped and then extruded with a layer of polyethylene inner sheath. Double-sided plastic coated steel tape (PSP) is longitudinally wrapped and then extruded with polyethylene sheath to form cables.

Feature:

● Adopting "SZ" bidirectional layer twisting technology
● Filling water-blocking ointment step by step, water-blocking in full section
● The steel (aluminum) belt has reliable bonding with the edge, high strength, and no cracking when twisted
● Stable fiber excess length control
● After the cable is formed, the additional attenuation of the fiber is almost zero, and the dispersion value does not change
● Excellent environmental performance, applicable temperature range is -10 ℃ ~ + 70 ℃

Note:
1. For flame retardant cable, outer sheath can be made of low-smoke halogen-free (LSZH) material, and the type is GYTZS.
2.Upon customer’s request, cables with longitudinal color strip on outer sheath can be offered. More details, please refer to GYTA series.
3. Special cable structure can be designed and manufactured on customer’s request.

Cable Core

The loose tubes are stranded around the central strength member utilizing SZ. SZ stranding wraps the tubes in one direction for several turns, then in the other direction.
Central Strength Member
The central strength member is made of steel It provides both tensile and anti-buckling strength to the cable.
Loose Tube
Optical fibers are housed in jelly filled tube. The tube is manufactured with industry standard PBT. It is colored for easy identification according to the scheme shown above.
Water Blocking Material
Filling compound, the water blocking material between the loose tube and the inner sheath protect cable from water intrusion.
Armour
A corrugated steel tape and aluminum tape provide additional cable compression strength, maximum anti-crush property, rodent protection and bullet resistant performance.
Outer Jacket
A black high density polyethylene jacket is extruded over the cable core and corrugated steel tape armor as the sheath.
Cable Sheath Marking
Each cable have the following information clearly marked on the outer jacket of cables:
a. Name of manufacturer.
b. Year of manufacturer
c. Type of cable and fiber
d. Length mark (printing on each meter normally)
e. Or as customer’s requirements.





Application:

Suitable for overhead, pipeline, direct buried and other laying methods
