GYTY53 Communication Large Core Structure Fiber Optic Armoured
Cable
Constructure:
The structure of GYTY53 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. 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
Corrugated steel 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.
