Fault Finding & Network Repair

Rapidly diagnosing and resolving fibre optic network issues to minimise business downtime.

When your network goes down, every minute counts. A break in a fibre optic cable or a failing component can bring your business operations to a standstill. London Fibre Cabling provides an emergency fault finding and repair service designed to get you back online as quickly as possible.

Our engineers use advanced diagnostic equipment to pinpoint the exact location and nature of the fault, allowing for swift and effective repairs.

Advanced Diagnostics with OTDR Testing

The primary tool for fibre optic fault finding is the Optical Time-Domain Reflectometer (OTDR). This powerful device sends a pulse of light down the fibre and measures the light that is reflected back. By analysing the return signal, our engineers can:

  • Pinpoint the Exact Location of a Fault: An OTDR can tell us precisely how many metres down the cable a break or other fault is located.
  • Identify the Type of Fault: We can determine if the issue is a complete cable break, a poor splice, a tight bend (macro bend), or a failing connector.
  • Measure Signal Loss: The test can quantify the amount of signal loss (attenuation) at any point along the cable, helping to identify performance degradation issues.

This level of detailed analysis means we don't waste time guessing. We arrive on-site, test the cable, and know exactly where to go and what we need to do to fix the problem.

Our Repair Process

Rapid Deployment

We understand the urgency of network downtime and aim to get an engineer to your London site as quickly as possible.

Precise Fault Location

We begin by connecting an OTDR to your network to get an immediate and accurate diagnosis of the problem's location.

Expert Repair

Once the fault is located, we perform the necessary repair, which typically involves fusion splicing the damaged section of the cable.

Verification & Testing

After the repair, we re-test the cable to ensure the connection is strong and that network performance is fully restored.
