Independent Fibre Audit & Witness Testing

Before you accept a fibre installation and release payment, know it meets the specification. We act as your independent fibre specialist — no stake in the installation, just clear evidence.

★ Why Audit

Are the Results Really Right?

When an installer hands over a fibre network, the test results are usually produced by the same team that did the work. Wrong reference methods, missing links, incorrect pass criteria or results copied between links are more common than most clients realise.

An independent audit gives operators, consultants and main contractors confidence before sign-off — and a fair, evidence-based basis for any remedial work.

We sit between the installer’s results and your sign-off, and give a clear recommendation backed by retest evidence.

How It Works

A Clear Answer Before You Sign Off

We review the installer’s submitted OTDR and OLTS files, attend their testing where needed, and independently retest an agreed sample of links. Results are compared link by link.

Alongside the test data we inspect workmanship on site. You receive one report with our findings, photographs, retest results and a recommendation: accept, accept with conditions or reject.

FAQ

Frequently Asked Questions

How many links do you retest?

We agree the sample size with you at the start, based on the size of the installation and the level of confidence you need. Problems found in the sample can trigger a wider retest.

Do you work for the installer or for us?

For you. An audit is only useful if it is independent, so we report to the party commissioning the audit.

Can you audit an installation that has already been accepted?

Yes — for example before a warranty claim, an upgrade or a dispute. The same review, retest and inspection approach applies.

What happens if the installation fails?

The report sets out exactly what failed and why. Once the installer has corrected the defects, we can retest to close the record.
