Non-metallic optical cables available in stock

Non-metallic optical cables include non-armored and non-metallic armored fiber optic cables, using materials like aramid yarn or FRP rods for strength and protection without metallic components.Non-Armored Optical CablesNon-armored optical cables are lightweight and flexible cables that rely on non-metallic materials for mechanical strength rather than metallic armor. Key features include:Core: Optical fibers arranged in loose tubes or tight-buffered bundles.Strength Members: Fiber Reinforced Plastic (FRP) rods or aramid yarn (Kevlar) provide tensile strength and prevent buckling.Jacket Materials: PVC (Polyvinyl Chloride) for indoor use, LSZH (Low Smoke Zero Halogen) for fire safety, and PE (Polyethylene) for outdoor durability.Advantages: Easy to handle and install, cost-effective, and compliant with building codes.Limitations: Vulnerable to rodent damage and low crush resistance, making them less suitable for harsh outdoor environments or direct burial .Non-Metallic Armored Optical CablesNon-metallic armored cables, also called dielectric armored cables, provide additional protection without using metal. They are reinforced with aramid yarn or glass yarn instead of steel, offering:Tensile Strength and Crush Resistance: Protects fibers from mechanical stress and rodent damage.Electrical Safety: Fully dielectric design prevents conductivity, making them safe near live electrical lines or in high-voltage areas.Construction: Often gel-filled loose tube design to prevent moisture ingress and maintain stable optical performance.Applications: Suitable for direct burial, duct systems, aerial ADSS (All-Dielectric Self-Supporting) installations, railway and highway corridors, and areas prone to electrical hazards.Advantages: Lightweight, flexible, maintenance-free, and compliant with international standards like IEC 60794 and ITU-T G.652/G.657 .Summary of MaterialsNon-metallic optical cables use non-conductive materials for both strength and protection:Aramid Yarn (Kevlar): Provides tensile strength and rodent resistance.FRP Rods: Prevent fiber buckling and maintain structural integrity.Glass Yarn: Adds crush resistance in armored designs.Outer Jackets: PE, PVC, or LSZH depending on indoor/outdoor use and fire safety requirements .ApplicationsNon-metallic optical cables are ideal for:Indoor installations where flexibility and fire safety are important.Outdoor duct or aerial installations where electrical hazards exist.Environments requiring lightweight, corrosion-free, and maintenance-free solutions. These cables are widely used in telecommunications, industrial networks, and infrastructure projects where metallic components are undesirable or unsafe .
