Rugged and compact
The rugged VFI4 is designed for the rigors 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 un-documented 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.
