Fiber Optic Visual Fault Finder The hand held VFF5 visual fault finder is a light source used to locate breaks and bad connections in fibre optic cables. It is ideal to verify continuity, test and find breaks in LAN's, fibre data links and loops. The VFF5 is easy to use as it projects a red light into a fiber optic cable and when the user looks at the cable and light can be seen, this means there is a break.
