The following is a list of optical testing tools used for FTTx (Fiber to the x) network:
1. VFL (visual fault locator) is capable continuity check fiber link up to 15km, break/bend visual identifier for fibre along patch panel/hub areas, It is mainly applied in fibre link construction and troubleshooting at locations
where fibres are accessible.
2. Light source/ power meter or multimeter (bidirectional loss test set) Measures fibre link insertion loss, return loss and tests continuity, It is mainly applied in fibre link construction, network acceptance testing and troubleshooting. Power Meter could be used individually for Measures power output of equipment, used for equipment and fibre link running and troubleshooting. Power meter with clip-on device like aligner or bare fiber connector, could used for testing optical power in link, used for fibre troubleshooting at any location where fibres are accessible, even when connectors cannot be accessed.
3. PON power meter with 1310/1490/1550nm simultaneously Measures power levels of equipment and fibre link when OLT/ONT connected, Fibre link and equipment (ONT/OLT) turn-up and troubleshooting.
4. Inspection scope for visually check the end face of fiber optic connectors, this with/out automated Pass/Fail analysis according to IEC standard. it used for fibre connector assembly check and troubleshooting.
5. OTDR (Optical Time Domain Reflectometer) is a powerful tools for characterizing fiber link, applied in fibre link construction, acceptance, troubleshooting.
6. Fibre identifier, Identify and track traffic on fibre, may also estimate power output along link. Equipment and fibre troubleshooting at any location where fibres are accessible, even when connectors cannot be accessed.
7. Optical talk set Enables communication between engineers using cable link When two engineers are required for end to end test.
8. Optical Monitoring System, Monitor fibre networks Monitoring of fibre networks to locate fibre breaks or fibre/element degradations.
