OLS and OTDR Testing & Certification
Core Precision provides OLS and OTDR testing with fibre optic certification support for new installations, fault finding, repairs and project handovers. At Core Precision we only use the highest level of industry standard equipment.
Testing is a vital part of any fibre optic project. It helps confirm that the network has been installed correctly, that splices and connectors are performing as expected, and that the fibre link is ready for use.
Our team supports clients across the UK and worldwide with accurate testing and clear reporting.
What Is OTDR Testing?
OTDR stands for Optical Time Domain Reflectometer.
OTDR testing sends a light signal through the fibre and measures reflections along the link. This helps identify events such as splices, connectors, bends, breaks and loss points.
The result is a trace that shows how the fibre is performing across its length.
What Is OLS Testing?
OLS stands for Optical Light Source.
OLS testing sends a controlled light signal through the fibre link, usually from one end of the cable, while a power meter measures the signal received at the other end.
This test checks the overall loss across the fibre link and helps confirm whether the connection is performing within the required limits.
The result shows how much light is being lost through the cable, connectors and splices, giving a clear pass or fail reading for the installed fibre.
Why OTDR Testing Matters
OTDR testing gives clients valuable proof of fibre performance. It can support:
Project handover
Network commissioning
Fault location
Repair verification
Quality assurance
Contractor sign-off
Future maintenance planning
Without proper testing, network issues may go unnoticed until they cause performance problems later.
OTDR Testing Services
Core Precision provides OTDR testing for a wide range of fibre networks. Our services include:
Fibre link testing

Connector event checks
Fault location
Bend and break identification
Pre-handover testing
Post-repair testing
Test result reporting
Fibre certification support
We can test fibre networks as part of an installation, repair project or independent review.
Testing for Installation and Handover
Fibre installation is not complete until the network has been tested.
Core Precision can provide testing after installation to support handover and project sign-off. This gives contractors, project managers and network owners confidence that the link has been checked properly.
Clear reporting also helps create a useful record for future maintenance.
Testing for Fault Finding and Repairs
OTDR testing is also useful when a fibre network is not working as expected.
It can help locate where a fault is likely to be and support faster repair decisions. After the repair, testing can confirm whether the link has been restored.
This makes OTDR testing an important part of both diagnosis and quality control.
FAQs
What is OTDR testing used for?
OTDR testing is used to check fibre performance and locate events such as splices, bends, breaks, connectors and loss points.
Do you work outside the UK?
Yes. Core Precision is UK-based but supports fibre optic projects both nationally and internationally.
Can OTDR testing find fibre faults?
Yes. OTDR testing can help locate faults along a fibre route, including breaks, bends and high loss events.
Do you provide reports?
Yes. Core Precision can provide test results and reporting to support project handover or repair records.
