Compact Structure, Robust Protection: Zhaolong Central Tube Outdoor Optical Cable — An Economical Choice for Outdoor Networking​

Introduction: Core Requirements for Outdoor Networking & Key Criteria for Optical Cable Selection

Outdoor networking faces multiple core challenges. Complex terrain (such as urban–rural gullies, park green belts) significantly increases cabling difficulty, while extreme temperature and humidity conditions (high-temperature sun exposure, severe cold, rain, and snow) can accelerate cable aging and damage. In addition, mechanical impacts from collisions or construction pulling may directly interrupt transmission, seriously affecting network stability and service life.

Meanwhile, most outdoor networking projects (e.g., small–medium parks, urban–rural access networks) operate under limited budgets, yet still require basic levels of protection and transmission stability from optical cables. Low-cost, inferior cables often lead to soaring maintenance expenses later, whereas premium cables may exceed budget limits. Finding a “cost‑performance fit” product thus becomes a critical factor in the procurement phase.

Zhaolong LONGNET GYXTW central tube outdoor optical fibre cable precisely matches this need. With compact structure + robust protection as its core advantages, it addresses cabling and protection pain points in complex outdoor environments, while streamlined structure and mature manufacturing processes keep costs under control. It serves as a high-value solution for mainstream outdoor deployment scenarios such as duct installation and non-self-supporting aerial cabling.

Core Advantages Analysis: Compact Structure + Robust Protection for Harsh Outdoor Conditions

We now examine the strengths of Zhaolong LONGNET GYXTW central tube outdoor optical cable from two perspectives:

• Compact Structure Design: Small Size, High Adaptability

• Central Tube Core Structure Explained: Simplified layout dramatically reduces cable outer diameter.

• Practical Value of Compact Structure: Facilitates duct installation, saves construction space, and lowers cabling difficulty.

• All-Round Robust Protection: Confidently Handles Complex Outdoor Conditions

• Mechanical Protection: Our company's GYXTW/GYXTZW outdoor optical cables use pigmented bare fibers, which are then loosely inserted into PBT buffer tubes filled with water-blocking compound. Using a central tube structure, the loose tube is longitudinally wrapped with PSP double-coated steel tape; two parallel steel wires are placed on either side before extruding the outer sheath, ensuring excellent tensile strength.

• Water Blocking Protection: Water-blocking material between the steel tape and loose tube effectively prevents moisture ingress, safeguarding transmission stability.

• Environmental Adaptability: Operating temperature range –40 °C to +60 °C suits diverse regional outdoor temperature variations; dynamic bending radius 20×cable OD, static 10× cable OD, allowing flexible routing.

Product Core Parameters & Flexible Configuration: Precisely Matches Diverse Networking Needs

Beyond structural and protective advantages, our GYXTW cable excels in configuration options and physical characteristics, fitting personalized requirements for different outdoor networks:

• Flexible Core Configurations

• Fiber Types: Available in OS2 single-mode and OM3/OM4 multi-mode options to meet varied networking needs. OS2 single-mode suits long-distance outdoor transmission; OM3/OM4 multi-mode satisfies medium-short distance high-bandwidth demands, ensuring every project scale and transmission requirement finds a matching solution.

• Fiber Count: 2, 4, 6, 8, 12, and 24 cores available for flexible pairing based on node count. 2–8 cores suit small parks, security monitoring, and simple outdoor networks; 12–24 cores meet multi-node connection needs for medium parks and urban-rural area access, covering small–medium scale outdoor networking scenarios comprehensively.

• Key Physical Characteristics & Environmental Assurance

• Core Physical Parameters:

• Bending performance: Dynamic bending radius ≥ 20× cable OD; static ≥ 10× cable OD, enabling complex path routing.

• Mechanical protection: Short-term tensile ≥ 1500N, long-term ≥ 600N; short-term crush ≥ 1000N/100mm, long-term ≥ 300N/100mm — outstanding resistance to external damage.

• Operating temperature: –40 °C to +60 °C, adaptable to extreme climates across regions, ensuring all‑condition stable operation.

• Eco-Materials & RoHS Compliance: Manufactured with fully environmentally friendly materials, strictly compliant with RoHS directive, free from hazardous substance release. Suitable for green parks and eco-friendly communication projects, reducing environmental impact and aligning with sustainability trends.

Applicable Scenarios & Installation Methods: High-Adaptability Choice for Outdoor Networking

Based on the above structure, protection advantages, and flexible configurations, Zhaolong LONGNET GYXTW central tube outdoor optical cable precisely fits multiple outdoor deployment scenarios and application fields, maximizing product adaptability value:

• Core Deployment Scenarios: Duct installation, non-self-supporting aerial cabling.

• Typical Application Fields: Outdoor networking for parks, urban–rural communication access, outdoor cabling for security surveillance, and remote network interconnection between various buildings/facilities.

• Scenario Adaptation Advantages: Compact structure suits duct resources; robust protection adapts to outdoor aerial environments; economical cost aligns with small–medium project budgets.
