Diamond Optics – 2 Fibre Single Mode LC Indoor Ruggedised Fibre Breakout cable

Product Description

The 2 Fibre Single Mode LC Indoor Ruggedised Fibre Breakout Cable is engineered to deliver the cleanest possible signal path for high-performance audio systems. Originally designed for carrier-grade telecommunications and internal building installations, this cable is ideal for running through walls, ceilings, and conduit, making it perfectly suited for permanent in-home audio infrastructure.

Utilising single-mode fibre (OS2 9/125μm), this solution provides complete galvanic isolation between network components, eliminating the transfer of electrical noise that can degrade audio performance. It is an ideal choice for connecting network switches, media converters, or streamers in systems where ultimate clarity and precision are required.

The ruggedised breakout design ensures durability during installation, while maintaining exceptional signal integrity even in tight spaces. Its bend-insensitive G.657.A1 fibre minimises signal loss when routed through walls or conduit, and precision LC connectors deliver low insertion loss and high return loss for stable, high-speed data transmission.

In high-end streaming systems, fibre optic connections reduce jitter and background noise, allowing your system to reproduce music with greater transparency, improved imaging, and a more natural soundstage.

 Key Features

• Designed for in-wall and conduit installations
• Complete galvanic isolation for noise-free audio systems
• Carrier-grade fibre adapted for high-end audio performance
• Bend-insensitive design for flexible routing
• Ultra-low insertion loss for maximum signal integrity
• Ideal for network audio, streamers, and fibre media converters

Build a True High-Performance Audio Network

For the ultimate streaming performance, this fibre cable is best used as part of a complete fibre-isolated network path. By converting your network from copper to optical, you eliminate electrical noise at its source and create a cleaner, more stable foundation for digital audio.

Recommended Setup

1. Router → Fibre Media Converter (or Optical Switch)
Convert your standard Ethernet output to optical signal.

2. Fibre Optic Link (This Cable)
Run fibre internally through walls or conduit to your audio system, ensuring complete galvanic isolation.

3. Fibre Media Converter / Network Switch → Streamer
Convert back to Ethernet just before your streamer or use a high-performance switch such as the LHY Audio AS6 to further refine the signal.

 Why This Matters for Audio

• Eliminates electrical noise between network devices
• Reduces jitter caused by unstable network conditions
• Improves timing accuracy for digital playback
• Creates a lower noise floor and more natural presentation

What You’ll Hear

When implemented correctly, users typically experience:

• Greater soundstage depth and width
• More precise imaging
• Tighter, more controlled bass
• Blacker background and improved detail retrieval
