OWL Optical Fiber Length Testers

OWL Optical Fiber Length Testers offer two Unique Economical Alternatives in Fiber Optical Length Measurements

OWL Optical Fiber Length Testers BOLT-NL uses a “looped” method of measuring fiber length. This is accomplished by looping back two fibers at one end of the fiber run with a patch cord. The round trip time that the light takes to travel through the fibers is converted to length in kilometers, then divided by two to show the length of the fiber cable. There is no need to measure the length of all the fibers; the length measurement can be applied to all fibers in the cable. This method of length testing provides accurate measurements, and saves time and money. The BOLT-NL measures fiber links of up to 25 kilometers, and is accurate to within ±2.5 meters. Pulsing mode allows for fiber location with fiber identifiers.

OWL Optical Fiber Length Testers VOLT (VISUAL OPTICAL LENGTH TESTER)

OWL’s VOLT functions as as one of the outstanding quality Visual Fault Locator (VFL). It however has VFL’s VOLT  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!
