Introduction to GYFXY Optical Cable Reinforced with Aramid Yarn

1. Model Definition

GYFXY refers to outdoor central loose tube all-dielectric filled optical cable with PE sheath.

GY: Outdoor telecommunication optical cable

F: Fully non-metallic strength member

X: Central loose tube structure

Y: PE outer sheath

Standard GYFXY only adopts two parallel FRP glass fiber rods for tensile resistance. GYFXY reinforced with aramid yarn adds multi-layer aramid yarn wrapped around the loose tube, forming a dual tensile reinforcement system of FRP + aramid yarn, also known as air-blown GYFXTY cable.

2. Layered Structure (From Inner to Outer)

Optical Unit 250μm single-mode fiber (G.652D as standard, fiber count: 2~24 cores) is housed in high-modulus PBT loose tube. The tube is filled with water-blocking jelly with excess fiber length reserved, to prevent water ingress, resist bending and reduce micro-bending loss.

Aramid Yarn Reinforcement Layer (Upgraded Core Component) High-modulus para-aramid yarn is helically wrapped outside the loose tube. Combined with two side FRP rods, it provides ultra-high tensile strength. Aramid yarn features lightweight, non-conductive, wide temperature resistance, chemical corrosion resistance and flame retardancy, free of electromagnetic induction.

Water-Blocking Buffer Layer Water-blocking tape is longitudinally wrapped outside aramid yarn to block longitudinal water vapor penetration.

Outer Sheath Black HDPE polyethylene sheath with excellent UV resistance for outdoor use. LSZH low-smoke zero-halogen flame-retardant sheath is optional for tunnels and indoor building wiring.

3. Advantages of Aramid Reinforced GYFXY vs Standard FRP-only GYFXY

Greatly enhanced tensile capacity Short-term tensile strength rises from 1000N (standard type) to 2000~5000N, suitable for long-span aerial laying, air-blowing and long-distance pulling without fiber breakage.

All-dielectric lightning protection & anti-electromagnetic interference No metal components inside the whole cable, free from lightning induction and RF interference, safe for deployment near high-voltage power facilities.

Lightweight & flexible for easy installation Lower density than steel, smaller outer diameter and lighter weight under same tensile load; superior bending performance without brittle fracture.

Stable performance under extreme temperature Low thermal expansion coefficient avoids fiber extra loss caused by sheath shrinkage under temperature change, and provides cushioning against external impact.

Perfect for air-blown microduct installation Compact outer diameter and low friction coefficient enable quick air-blow laying inside existing microducts without new trenching.
