  • GYTZA53 Heavy-Armoured Flame-Retardant Cable for Harsh Routes

Product Description

The structure of GYTZA53 optical cable consists of 250 μm optical fibers 

encased in loose tubes made of high-modulus material, filled with 

a waterproof compound. The center of the cable core is a metallic central 

strength member. For certain fiber counts, a layer of Polyethylene (PE) is 

extruded over the central metallic strength member. The loose tubes 

(and filler rods) are stranded around the central strength member into 

a compact and circular cable core, with the core interstices filled with 

a water-blocking compound. After longitudinal application of coated 

aluminum tape (APL), an inner PE sheath is extruded. Subsequently, 

double-sided plastic-coated steel tape (PSP) is longitudinally applied 

before extruding the flameretardant outer sheath to complete the cable assembly.

Product Features

Mechanical & Thermal Performance: Excellent mechanical properties and 

temperature characteristics.

Anti-Shrinkage Design: Specially designed compact structure prevents 

loose tube retraction effectively.

Hydrolysis Resistance & High Strength: Loose tube material exhibits 

superior hydrolysis resistance and high strength.

Crush Resistance & Flexibility: Delivers good crush resistance 

and installation flexibility.

Critical Fiber Protection: Tubes filled with special waterproof 

jelly ensure essential protection for optical fibers.

Custom Flame-Retardance: Flame-retardant GYTZA53 optical 

cable models can be customized upon request.

Frequently Asked Questions

What is the Loose Tube Stranded Heavy-Armored Flame-Retardant Optical Cable (GYTZA53) used for?

Huifiber GYTZA53 is a double-sheathed, steel-tape armored loose tube outdoor optical cable featuring exceptional flame retardancy, moisture resistance.

Can Huifiber customise the Loose Tube Stranded Heavy-Armored Flame-Retardant Optical Cable (GYTZA53)?

Yes. Huifiber supplies cable under the buyer's own brand as well as under the Huifiber brand. Fibre count, jacket material, jacket print, drum marking, drum length, packaging and datasheet layout can all be produced to the customer's requirement, and the engineering team can work from a customer specification or adapt an existing construction to a new route requirement.

How is the Loose Tube Stranded Heavy-Armored Flame-Retardant Optical Cable (GYTZA53) tested before shipment?

Every production batch is tested before it leaves the plant in Dongguan. Attenuation and geometry are measured on OTDR and optical bench equipment, and mechanical performance is verified against the datasheet for the construction. A factory test report is issued with each shipment, so an incoming inspection can be checked against the same numbers.

What should I send for a Loose Tube Stranded Heavy-Armored Flame-Retardant Optical Cable (GYTZA53) quotation?

Send the fibre count and fibre type, the jacket material or fire rating, the route length or span and the drum length you need, the destination port or country, and any certification or test-report requirement. With those details the sales engineer can confirm the construction and return a quotation with an indicative lead time.
