Test and Inspection
HiLite VFI4
Visual fault identifier
Bypass OTDR limitations, pinpoint faults faster with the HiLite VF14.


The VFi4 is a visible laser source.
It will help you easily identify and trace fibres during activation and installation.
AFL Test & Inspection HiLite visible red laser source from AFL is designed to troubleshoot faults in fibre optic cables. Light generated by these units will escape from sharp bends and breaks in jacketed or bare fibres, as well as poorly mated connectors. The HiLite VFI4 can quickly identify faults in fibre optic jumper cables, distribution frames, patch panels, and splice trays.
Many fibre network defects occur within the first few meters – within typical OTDR dead zones. HiLite is an excellent complement to any OTDR because it can locate faults inside the OTDR’s dead zone. Other applications include end-to-end continuity checks, as well as identifying connectors in patch panels and fibres during splicing operations. The universal connector interface mates with many connector styles without needing an adapter.
AFL’s compact VFI4 injects high-powered red-laser light to provide exceptional brightness and range for locating defects in single-mode and multimode fibres. The light generated by these units will escape from sharp bends and breaks in jacketed or bare fibres, as well as poorly mated connectors enabling technicians to quickly spot faults. The universal connector interface mates with many connector styles without needing an adapter.
Fujikura Europe is the authorised distributor for AFL test & measurement products in the UK. In addition, Fujikura Europe is the approved calibration & repair centre for AFL Test & Inspection products in Europe.
Key Features
Rugged and compact
The rugged VFI4 is designed for the rigours of real-life field testing. It has a range of up to 10 km, fits on a keychain, and features extensions that protect the red-laser port. It has both CW and pulsating modes and is powered by a single AA battery for up to 30 hours of operation.
Installation and activation
VFI4 is used for quick continuity checks, fibre tracing, splice verification, and Pass/Fail validation for mechanical connectors. VFI4 is also an excellent complement to any OTDR because it can locate faults inside the OTDR’s dead zone.
The essential troubleshooting tool
The VFI4 highlights sharp bends, breaks, faulty connectors, and other defects that “leak” light. Other applications include end-to-end continuity checks, as well as identifying connectors in patch panels and fibres during splicing operations.
Trace cables in crowded or undocumented setups
A HiLite is a quick means of finding the "other end" from amongst cluttered cables. Simply connect to one end and look for the visible red light transmitted out the opposite connector.
