Product Description
The structure of GYTZA/S 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 double-sided plastic-coated aluminum tape (APL) or steel tape (PSP), a flame-retardant
outer sheath is extruded 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 GYTZA/S optical cable
models can be customized upon request.

Values are typical reference data taken from the official Huifiber datasheet. Confirm the final specification against the datasheet before ordering.
Huifiber GYTZA & GYTS loose tube armored outdoor optical cables offer excellent moisture resistance, tensile strength, and flame-retardant properties.
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.
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.
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.
