Do I need my network cabling tested and certified?

Two cable runs can look identical and perform very differently. A kinked cable, a poor termination or a run that is too long can all cause slow speeds and dropouts that are hard to pin down. Testing and certification tells you exactly how each link performs.

What is cable certification?

Certification uses a dedicated tester, such as a Fluke DSX, to measure every link against the industry standard for its category, for example Cat6 or Cat6a. Each link gets a pass or fail, with detailed measurements of things like length, loss and crosstalk. You receive a report covering every point.

Is a simple continuity tester enough?

No. A basic tester only checks that the wires are connected in the right order. A link can pass that check and still fail to carry full speed. Only a certification tester measures performance.

When should you have cabling certified?

  • After a new installation, before you sign it off. You have proof the work meets the standard.

  • When you move into a building with existing cabling. You find out what you are inheriting.

  • When you want a manufacturer warranty. Most extended system warranties require certified test results.

  • When you have unexplained slow speeds or dropouts. Testing quickly shows whether the cabling is the cause.

What you receive

A full report listing every link, its result and its measurements, plus labelling that matches the report so any point can be traced quickly. Keep it with your building records. It is useful for future upgrades and for anyone who works on the network later.
