GYFXTZS Flame-Retardant Aramid Yarn + CST Armored Uni-tube Fiber Optic Cable

GYFXTZS Outdoor Central Tube LSZH Jacket Aramid Yarn reinforced Steel Tape Armored Fiber Optic Cable for Duct/Aerial Installation

Fibers: 2-12 core

Standard Reel Length: 2km, 3km, 4km (other length also available)

Cable Construction:

The 2-12core Fibers (Single-Mode or Multi-Mode) are positioned in a central tube made of high-modulus plastic and filled with tube gel. The tube is reinforced with aramid yarns and water blocking yarns. Then the Corruagted Steel Tape (CST ) is armored around the cable core. Finally a LSZH jacket is extruded.

Product Overview

GYFXTZS flame-retardant unitube fiber optic cable combines aramid yarn reinforcement with Corrugated Steel Tape (CST) armor layers and LSZH Jacket—for exceptional tensile strength and fire protection. This hybrid design delivers up to 1500N tensile resistance and crush protection exceeding 1000N, certified for hazardous environments like oil refineries or military sites. It features a unibuffer tube filled with thixotropic gel to prevent moisture ingress and fiber micro-bending, while the Low Smoke Zero Halogen (LSZH) sheath reduces toxic fumes during fires. Compliant with IEC 60331 for fire integrity at 750°C for 90 minutes, this cable ensures reliable operation in EMI-prone areas, making it a top choice for critical infrastructure.

Features

• Steel Armor: Corrugated Steel Tape for moisture-proof and rodent protection.

• Aramid Yarn Reinforcement: High-tensile Kevlar® fibers provide superior pull strength and flexibility, reducing installation strain and enhancing durability.

• Flame Retardancy: Exceeds IEC 60331 standards, maintaining circuit integrity during prolonged fires for safe use in high-risk industrial zones.

• Environmental Sealing: Gel-filled uni-tube design blocks water and contaminants, with LSZH sheath emitting minimal smoke and no halogens per IEC 61034.

• Fiber Options: Supports G652D, bend-insensitive G.657 fibers for tight bends, with core counts from 2-12 for versatile network scaling.

• Laying Methods: Duct or Non self-supporting Aerial laying

Applications

· Petrochemical and Energy Facilities: Installed in refineries, power plants, and offshore platforms where explosion risks demand robust, fireproof cabling.

· Military and Defense Installations: Provides secure communication in bases or field operations, resisting physical attacks and harsh conditions.

· Utility and Grid Networks: Used in high-voltage transmission lines and substations for reliable data monitoring and control systems.

· Coastal and Subaqueous Deployments: Suitable for conduits in marine environments, with corrosion-resistant materials ensuring longevity in saltwater.

FAQ

Q: What chemical resistance does this cable offer for industrial use?

A:  It resists fuels, acids, and alkalis per IEC 60811 tests, with sheath materials designed for chemical exposure in plants or refineries.

Q: What is the approximate weight per kilometer for a standard configuration?

A:  For a 12 core version, the weight is approximately 75 kg/km, balancing strength with manageable handling during installation.

Q: What is the minimum recommended installation temperature?

A:  Installation can proceed at temperatures as low as -20°C without sheath brittleness, ensuring flexibility in cold climates.

Q: How does the double armor enhance EMI protection?

A:  The CST layer acts as a Faraday cage, blocking electromagnetic interference from nearby equipment, crucial for sensitive electronics.

Q: What is the cable's performance in high-humidity conditions?

A:  With gel filling and water-blocking tapes, it maintains low attenuation (≤0.1 dB/km) in 95% humidity, per IEC 60794-1-2.
