Australian Core Optical Cable

Australian Core Optical Cables are high-performance fibre optic cables designed for underground, direct burial, and outdoor installations, offering durability, moisture resistance, and compliance with local standards.

Overview

Australian core optical cables are engineered to deliver reliable data transmission across a variety of environments. They are typically loose tube or tight-buffered designs, often reinforced with aramid yarn or composite strength members to provide tensile strength and protection against mechanical stress, moisture, and termites . These cables are suitable for duct installation, direct burial, or open-cut trenches, and are designed to withstand harsh conditions including thermal shock, wind abrasion, and ice loading .

Construction and Features

• Fibre Types: Single-mode (OS1/OS2) and multi-mode (OM1, OM3, OM4) fibres are commonly used, meeting ITU-T G652.D standards for low water peak and high transmission performance .
• Sheath Materials: Polyethylene (PE) or Low Smoke Zero Halogen (LS0H) sheaths are used, sometimes with a bonded nylon layer for enhanced termite resistance and reduced friction during installation .
• Water Protection: Dry water-blocking systems or gel-filled tubes prevent moisture ingress along the cable length .
• Strength Members: Composite glass fibre reinforced plastic (GRP) or aramid yarn provides tensile and crush resistance, ensuring durability during pulling, jetting, or floating installation techniques .

Applications

Australian core optical cables are widely used in:

• Telecommunications networks for high-speed data transmission.
• Data centres and enterprise networks requiring high fibre density and reliability.
• Long-haul and metropolitan networks, where underground or direct-burial installation is necessary.
• Harsh environments, including areas prone to termites, moisture, or mechanical impact .

Local Manufacturing and Customisation

Several Australian companies manufacture and supply core optical cables:

• AFL Global produces a wide range of fibre optic cables in Tottenham, Victoria, suitable for above-ground, underground, and underwater applications .
• Prysmian offers the SM@RTCORE® and FlexTube ranges, which are compact, high-density loose tube cables designed for cost-effective installation and increased duct capacity .
• 4Cabling provides custom fibre optic cables with pre-terminated options, cut-to-length services, and factory-tested performance, with facilities in NSW, WA, and QLD .
• Nexans Australia manufactures aramid-reinforced, PE-sheathed cables for duct or direct burial, emphasizing water and termite resistance .

Installation Considerations

• Underground Ducts: Loose tube cables can be pulled, jetted, or floated into ducts.
• Direct Burial: Armoured or PE-sheathed cables are preferred for mechanical protection.
• Environmental Protection: LS0H or PE/nylon sheaths protect against UV, moisture, and termites.
• Fibre Identification: Individual fibres are colour-coded for easy identification during splicing and termination . Australian core optical cables combine robust construction, high fibre density, and local compliance, making them suitable for a wide range of telecommunications and data network applications across Australia.
