4 Core Fiber Optic Cable

Products Description

GYFXY Non-metallic Central Loose Tube Optical Cable

GYFXY is a non-metallic outdoor optical cable with central loose tube design. Optical fibers are housed inside a single high-modulus loose tube filled with water-blocking gel for fiber protection. Two parallel FRP strength members are placed on both sides of the loose tube, covered by an extruded black PE outer sheath.

The dual parallel FRP structure delivers reliable tensile performance. The all-dielectric construction eliminates metal components to avoid lightning strikes and electromagnetic interference. With hydrolysis-resistant loose tube and UV-stabilized PE sheath, this cable features small outer diameter and lightweight, simplifying field installation.

It is widely deployed in FTTx access networks and communication branch lines for duct installation and non-self-support aerial laying. Suitable environments include lightning-prone areas and zones near high-voltage lines with strong electromagnetic interference. Operating temperature: -40℃ ~ +70℃.

Overseas buyers prefer this model for its lightning resistance, easy handling and convenient fiber termination. Flexible production lengths make it ideal for FTTH last-mile and short-distance outdoor telecom projects for global operators and contractors.

Fiber Counts

GYFXY is available in 2–24 cores (2/4/6/8/12/16/24 fibers). Up to 24 optical fibers can be placed in this single central loose tube. Fiber options include G652D, G657A2 single-mode fibers, and multimode fibers upon custom request, matching various fiber distribution capacities for global FTTx projects.

Cross-section Structure & Materials

From inside to outside, the GYFXY cross-section consists of 250μm colored optical fibers, high-modulus PBT loose tube, water-blocking filling gel, longitudinal water-blocking material, two parallel FRP (Fiber Reinforced Plastic) strength members, and black UV-stabilized polyethylene (PE) outer sheath. All fibers are housed inside one single central loose tube with excellent hydrolysis resistance. The filling gel wraps fibers to block moisture ingress. Two symmetric parallel FRPs on both sides of the loose tube bear tensile load. The outer PE sheath delivers UV and weather resistance. Zero metal components, fully all-dielectric design.

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 have long-term cooperation with more than 30 countries and have 18 years' rich experience to export cables till now.

As a source factory deeply rooted in the optical cable manufacturing industry, we understand that every meter of optical cable carries the heavy responsibility entrusted by our customers for the stable operation of communication networks. Therefore, we have abandoned the traditional "sell-it-and-go" model, integrating "zero defects in quality" and "zero-distance service" into our corporate DNA. From raw material warehousing to optical cable decommissioning, we have built a dual-guarantee system covering the entire product lifecycle, ensuring customers can buy with confidence and use with peace of mind.

Strict Quality Control, Building a Solid Quality Defense Line

Source Control, Material Traceability: All core raw materials such as optical fibers, sheath materials, and reinforcement components are sourced from leading suppliers in the industry. Each batch of materials comes with an original factory inspection report and a unique traceability code. Before warehousing, materials undergo 12 rigorous tests, including tensile strength, temperature resistance, and flame retardancy. Substandard materials are resolutely rejected, eliminating potential quality risks from the source.

Process Monitoring, Standardized Manufacturing Processes: The production line is equipped with an online monitoring system that collects key parameters such as fiber attenuation, sheath thickness, and cable core roundness in real time. The data is automatically uploaded to the MES system, achieving full traceability throughout the production process. Each optical cable undergoes eight quality control checks before leaving the factory, including OTDR bidirectional testing, mechanical performance testing, and environmental adaptability testing. Test data is permanently archived to ensure that each cable meets GB/T 7424.1 and the highest industry standards.

Quality Commitment, Lifetime Responsibility: We promise a product warranty period of no less than 20 years. During the warranty period, we will replace any quality defects caused by materials or workmanship free of charge and bear the related installation costs. Even after the warranty period, we provide lifetime technical support and preferential repair services, giving customers peace of mind.

Construction-Packaged Technical Support

On-Site Technical Briefing: Before fiber optic cable laying, our engineers can conduct on-site technical briefings, focusing on key construction points such as colorimetric arrangement rules, bending radius control, and traction force distribution, to avoid hidden damage caused by improper operation.

Laying Process Inspection: At critical nodes of air-blowing or traction laying, we provide remote or on-site inspection services to monitor traction force, speed, and bending radius data in real time, ensuring that the construction process meets specifications.

Fusion Splicing Guidance and Acceptance: We provide fiber optic fusion splicing process guidance to assist the construction team in optimizing fusion parameters; after laying, we can cooperate in conducting OTDR bidirectional testing and acceptance to ensure that the attenuation, return loss, and other indicators of each fiber optic cable segment meet design standards, and issue a test report.

Our commitment: We craft quality with the dedication of our factory and safeguard trust with the warmth of our service. Choosing XX Optical Cable is not just choosing a product, but choosing a reliable long-term partner who accompanies you throughout the entire process. We are committed to ensuring the stable transmission of every fiber optic cable with superior quality and attentive service, growing together with our customers and achieving a win-win future.
