Outdoor Rated Fiber Optic Cable

30+ years

Our factory was found in 1992, first start with coaxial cable which was one of the biggest manufacturers in lin'an city.In year of 2001 started focusing on the production of optical cables.

30+ countries

In year of 2008, set up international sales department and sale optical fiber cable to more than 30 countries and have 18 years` rich experience to export cables .

• A layer of wrapped steel wires ensures the tensile strength of the cable, while protecting the loose tube, can play a very good role in rodent prevention.
• Good lateral compression resistance.
• Good mechanical and temperature performance.

*All above the cable size can be customized.

• Transport/storage temperature: -40℃ to +60℃

• Standard reel length: 2km/drum or 3km/drum; other lengths are also available.

The delivery time for small batches of products is 7-15 days, for large batches it is 15-25 days. If there is an urgent need, please inform us in advance, and we will try our best to coordinate during production.

GYXTY is an outdoor communication optical cable with a centrally bundled tube, steel wire wrapped armor, and polyethylene sheath. Its unique steel wire wrapped structure provides rodent protection and it is widely used in pipeline and overhead laying scenarios.

Structure of GYXTY (Inside Out):

Fiber Optic: 250μm coated fiber centrally located in the core.

Loose Tube: Made of high-modulus polyester (PBT), encasing the fiber optic cable.

Tube Filler: Special waterproof grease inside the loose tube, providing essential protection for the fiber optic cable.

Water-Blocking Material: Additional water-blocking layer (water-blocking cable grease or yarn) outside the loose tube for longitudinal water resistance.

Steel Wire Armor Layer: Multiple (usually 12) phosphated steel wires twisted and wrapped around the loose tube-this is the core rodent-proof design of GYXTY.

PE Sheath: Outermost extruded polyethylene sheath, resistant to ultraviolet radiation.

Steel Wire Wrapped Armor – The Core of Rodent Protection:

This is the key design difference between GYXTY and GYXTW cables.

GYXTY uses multiple phosphated steel wires twisted and wrapped around the loose tube, forming a dense metal armor layer. This hard steel wire layer effectively prevents rodents from penetrating and damaging the internal optical fibers when gnawing occurs.

GYXTW uses a double-sided plastic-coated steel tape (PSP) longitudinal wrapping combined with parallel steel wires on both sides. This design focuses more on lateral pressure resistance and moisture protection, but its rodent protection is less effective compared to the steel wire wrapping of GYXTY.

Central Loose Tube Compact Structure:
All optical fibers are housed within a single loose tube, creating a compact design with a small outer diameter and lightweight profile. For instance, cables with 2-12 cores have an outer diameter of about 7.7mm and weigh approximately 76kg/km, facilitating easier installation.

Double Water-Blocking System:

Inside the loose tube: a special waterproof compound directly protects the optical fibers.

Outside the loose tube: water-blocking cable paste or yarn fills the gaps between the steel wire and the loose tube, providing longitudinal water blocking.
This dual defense ensures long-term stable performance in humid environments.

Special Treatment of Phosphated Steel Wire:
The steel wire wrapping is phosphate-treated, which enhances bonding strength and corrosion resistance between the steel wire and cable core. The phosphate layer also acts as a rodent repellent due to the odor sensitivity of rodents.

Excellent Rodent-Proof Performance:
Multiple phosphated steel wires are twisted and wrapped tightly to form a dense armor layer that rodents cannot chew through. This makes the cable particularly suitable for areas with severe rodent infestations, which is why the GYXTY cable is named "rodent-proof."

Outstanding Mechanical Properties:

Permissible tensile force:

Long-term: 600N

Short-term: 1500N (for 2–12 cores)

For 14 cores and above: 1000N long-term / 3000N short-term

Permissible compressive force:

Long-term: 1000N/100mm

Short-term: 3000N/100mm

The cable also offers strong lateral pressure resistance and excellent flexibility.

Typical Application Scenarios:

Pipelines and overhead communication lines in areas with severe rodent infestation

Long-distance and inter-office communications

Urban access networks and rural communications

Computer network systems and CATV cable television networks

Situations requiring rodent protection while maintaining a small outer diameter and lightweight design

For areas with particularly severe rodent infestations or where stronger protection is needed (such as direct burial scenarios), the GYXTY53 model is recommended. It enhances the GYXTY design by adding a double armor structure consisting of a PE inner sheath, PSP steel strip longitudinal wrapping, and PE outer sheath. This upgrade significantly improves rodent resistance and pressure endurance, with tensile strength reaching up to 1000N long-term / 3000N short-term.

As a source factory with a long history in optical cable manufacturing, we recognize that every meter of optical cable is entrusted by our customers to ensure the stable operation of communication networks. Therefore, we have moved beyond the traditional "sell-it-or-lose-it" model, embedding "zero defects in quality" and "zero distance in service" into our corporate DNA.

We have established a dual guarantee system covering the entire product lifecycle-from raw material storage to optical cable decommissioning-so our customers can purchase with confidence and operate with peace of mind.

Strict Quality Control, Building a Solid Quality Defense Line

Source Control and Material Traceability: All core raw materials-including optical fibers, sheath materials, and reinforcing components-are sourced from leading industry suppliers. Each batch is accompanied by the original manufacturer's quality inspection report and a unique traceability code. Before warehousing, materials undergo 12 rigorous tests, such as tensile strength, temperature resistance, and flame retardancy. Substandard materials are strictly rejected, eliminating potential quality risks at the source.

Process Monitoring and Standardized Manufacturing: Our production line features an online monitoring system that collects key parameters in real time, including fiber attenuation, sheath thickness, and core roundness. This data is automatically uploaded to the MES system, ensuring full traceability throughout the production process. Each reel of optical cable passes through eight quality inspection checkpoints before leaving the factory, including OTDR bidirectional testing, mechanical performance testing, and environmental adaptability testing. Test data is permanently archived, guaranteeing that every reel meets GB/T 7424.1 and the highest industry standards.

Quality Commitment and Lifetime Responsibility: We provide a product warranty of no less than 20 years. During this period, any quality defects caused by material or workmanship issues will be repaired or replaced free of charge, including related construction costs. Even after the warranty expires, we continue to offer lifetime technical support and preferential repair services, ensuring our customers have complete peace of mind.

Bending loss in optical fibers is influenced by several key factors: a smaller bending radius leads to exponentially increased loss; longer operating wavelengths, such as 1550nm and 1625nm, face greater bending loss; single-mode fibers are more susceptible to bending than multimode fibers; and structural design elements, including core size and refractive index distribution, significantly impact bending resistance.
