Almost all fiber optic experts own a VFL similar to VOLT but they don't get the extra benefit length testing features of VOLT !

VOLT functions as any good quality Visual Fault Locator (VFL). However, with the same price range as other VFL's VOLT has the added benefit of doubling as a LOOPING length tester! Many cabling warranties and bids are requiring meter based length tests to prove length of links.

VOLT uses 2 fibers and patch cables to establish a length test accurate to +/- 7 feet ! VOLT's VFL functions up to 5 Kilometers (3.1 Miles). Loop length testing functions up to 1.5 Kilometers.

As far as VFL function, VOLT holds its own against the best in the industry. As with any quality VFL VOLT is a precision coupled laser diode! VOLT is not made as a cheap laser light pen is designed! Rather, a multi-million dollar semiconductor machine is used in the manufacture of a special precision coupled micro sized ball lens. This precision coupling allows VOLT to couple maximum red laser light into the tiny connector orifice of fiber optic links up to 5 Kilometers (3.1 Miles) of distance!
