Fibre Optic Testing & Certification
Professional Fibre Testing, Fault Diagnosis & Network Certification
FibreTel Networks Design Ltd provides professional fibre optic testing and certification services for new installations, existing networks, upgrades and fault investigations.
From individual fibre links to backbone and data centre infrastructure, we verify optical performance, identify faults and provide clear test documentation to support commissioning and project handover.
Testing & Characterisation Services
Connector Inspection & Verification
Inspection of fibre connector end faces to identify contamination, damage and defects that could affect optical performance. Cleaning and re-inspection can be completed before certification testing.
Insertion Loss Testing
End-to-end optical loss measurement to verify fibre link performance against the required loss budget and project specification.
Optical Return Loss (ORL) & Reflectance Testing
Measurement and assessment of reflected optical power to identify connectors, splices or other events that may affect network performance.
OTDR Testing & Analysis
Detailed analysis of the complete fibre route to locate splices, connectors, bends, breaks and abnormal loss events while assessing overall fibre attenuation.
Spectral Attenuation Testing
Measurement of fibre attenuation across multiple wavelengths to assess suitability for wavelength-dependent and WDM optical transmission systems.
Chromatic Dispersion (CD) Testing
Characterisation of chromatic dispersion across the fibre link to support high-speed and long-distance optical transmission requirements.
Polarisation Mode Dispersion (PMD) Testing
Measurement of PMD characteristics to assess fibre suitability for high-capacity and high-speed optical transmission systems.
OLTS / Tier 1 Certification
Optical loss, length, continuity and polarity verification for installed fibre links.
Bi-Directional OTDR Testing
Testing from both ends of a fibre link to provide improved assessment of event and splice losses.
Fibre Fault Finding
Investigation and location of fibre breaks, excessive losses, poor splices, damaged connectors and other optical network faults.
Post-Remediation Re-Testing
Re-testing following repair, re-splicing or network remediation to confirm the link meets the required performance criteria.
Test Reports & Certification
Clear test results and supporting documentation for commissioning, acceptance and client handover.
Advanced Characterisation Note
Advanced fibre characterisation testing, including CD, PMD and spectral attenuation, is available subject to project requirements and network specifications.
