Outdoor GYXTW 24 core armored cable

Product Introduction

The GYXTW optical cable represents a highly engineered central loose tube design, specifically manufactured for demanding outdoor trunk and access network infrastructures. At its core, this configuration contains six premium G.652D single-mode fibers enclosed within a durable polybutylene terephthalate (PBT) loose tube, which is completely filled with a specialized water-blocking thixotropic gel. To guarantee absolute compactness and formidable watertightness, the tube is longitudinally wrapped with a corrugated steel tape (PSP) integrated with advanced water-blocking materials. Flanking the steel tape, two parallel steel wire strength members are embedded to deliver exceptional tensile strength. The entire internal structure is hermetically sealed within a dense, black polyethylene (PE) outer sheath, providing a smooth tactile finish while delivering supreme resistance against ultraviolet radiation, moisture ingress, and environmental degradation. Engineered to perform flawlessly across extreme temperature ranges from -40 °C to +70 °C, this armored cable is the definitive choice for long-distance telecommunications, CATV networks, and industrial automation deployments requiring reliable duct, aerial, or direct burial installations. It boasts a long-term tensile strength of 400 N and an impressive short-term crush resistance of up to 1000 N/10cm, ensuring physical integrity during complex routing.

Product Advantage

1. Central Loose Tube Design with Full Water-Blocking Protection

The architectural foundation of this cable relies on an advanced central loose tube constructed from premium PBT material, meticulously engineered to house six G.652D single-mode fibers. Inside this core, a specially formulated water-resistant gel surrounds the fibers, providing a crucial hydrostatic barrier. The exterior of the tube is further fortified with advanced water-blocking materials and a longitudinally applied corrugated steel tape (PSP). This multi-layered defense mechanism ensures absolute watertightness, actively preventing moisture ingress even when the cable is submerged in flooded ducts or subjected to damp, direct-buried environments. Beyond moisture protection, the internal gel acts as a mechanical shock absorber, cushioning the delicate glass fibers against micro-bending and external vibrations. This meticulous internal engineering guarantees that signal attenuation remains exceptionally low, securing reliable data transmission over decades of continuous outdoor service.

2. Dual Steel Wire Armor for High Tensile Strength

To combat the intense physical stresses of outdoor deployment, two parallel steel wires are strategically positioned on opposite sides of the corrugated steel tape. This dual-wire armoring system grants the cable extraordinary tensile capabilities, allowing it to comfortably withstand a long-term continuous tension of 400 N and sudden short-term tension spikes up to 800 N without transferring any damaging stress to the internal optical fibers. Such formidable structural integrity makes this cable the ultimate solution for demanding long-span aerial installations, steep-slope deployments, and high-pull tension scenarios where standard unarmored cables would be highly susceptible to structural failure or severe signal degradation. Furthermore, this metallic barrier acts as an impenetrable shield against gnawing rodents, significantly reducing the risk of wildlife-induced network outages in rural or heavily forested installation zones.

3. Robust Crush and Impact Resistance

Navigating complex installation environments requires a cable that can endure severe mechanical abuse. Boasting a formidable short-term crush resistance of 1000 N/10cm alongside a dynamic bend radius of just 20 times the cable diameter, this product is specifically built to survive harsh handling. The synergistic combination of the corrugated PSP armoring and the dual steel strength members forms a rigid yet surprisingly flexible protective exoskeleton. This defensive layer effectively isolates the fragile optical cores from localized point loads, accidental impacts from heavy construction equipment, and abrasive rock friction commonly encountered during direct burial procedures. Despite its rugged exterior, the cable maintains a relatively small outer diameter and excellent flexibility, ensuring smooth routing through narrow underground conduits and complex cable trays. Extensive field testing verifies its ability to maintain peak optical performance even after repeated crushing and bending cycles.

4. Wide Operating Temperature for Extreme Climates

Environmental volatility poses a significant threat to outdoor communication networks, but this armored cable is engineered to conquer extreme climatic fluctuations. It guarantees stable operation across a drastic temperature spectrum from -40 °C to +70 °C, while safely supporting active installation procedures between -20 °C and +60 °C. The exterior is wrapped in a dense, industrial-grade black polyethylene (PE) sheath that feels remarkably tough to the touch. This specialized PE compound provides an impenetrable barrier against intense ultraviolet (UV) radiation, ozone exposure, and corrosive chemical elements present in the soil or atmosphere. Whether deployed in blistering desert heat, freezing arctic tundras, or high-humidity tropical regions, the outer jacket prevents cracking, swelling, or degradation. This exceptional thermal and chemical resilience ensures uninterrupted signal transmission year-round, drastically minimizing emergency maintenance calls and reducing the total cost of ownership for network operators.

5. Excellent Optical Performance with G.652D Fiber

At the heart of its transmission capabilities, the cable utilizes six meticulously crafted G.652D single-mode fibers that deliver industry-leading optical clarity. These fibers exhibit exceptionally low attenuation rates—strictly maintained at ≤0.36 dB/km at the 1310 nm wavelength and an even more impressive ≤0.25 dB/km at the 1550 nm window. This minimal signal loss empowers network architects to design long-haul transmission links spanning tens of kilometers without the costly requirement of intermediate signal repeaters. Furthermore, the cable's cutoff wavelength is precisely engineered to be ≤1260 nm, ensuring flawless single-mode operation across all standard telecommunication bands. Manufactured in strict compliance with ITU-T international standards, this optical core provides the pristine signal integrity mandatory for high-capacity backbone networks, extensive FTTX distribution grids, and critical metropolitan area networks where data latency and packet loss are simply unacceptable.
