• OWL BOLT-NL Precision Coupled Visual Fault Locator

  OWL BOLT-NL Beaming Optical Fiber Length Tester OWL's BOLT-NL (Beaming Optical Length Tester) ~ Accurate to +/- 2.5 meters for optical fiber lengths up to 25 KM OWL's BOLT-NL (Beaming Optical Length Tester) is designed to measure the end-to-end length of a fiber cable.  A pair of terminated fibers, looped back at the far end of the cable, are required for end-to-end fiber cable length measurement.The 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. OWL's BOLT optical fiber length tester save time by eliminating the need to measure fiber by the cable jacket. Fiber links may also go through multiple cross-connects or have splices in the middle, thereby making jacket markings invalid. Optical measurement of fiber produces accurate results without the need for jacket markings. Optical measurement also saves time by eliminating the need to estimate the length of the fiber run with a measuring wheel. This method is especially troublesome and inaccurate in networks that traverse walls, are in a star topology, or contain riser cables. 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.   . Link to Ordering information

• OWL BOLT-NL Beaming Optical Length Tester Features & Specifications Model Number: BOLT-NL Optical Fiber Length Range : 25KM (82,000ft)(15.5 miles) Length Accuracy: +/- 2.5 Meters Generates a 2kHz pulsed signal for use with fiber identifiers Size: 4.94 x 2.75 x 1.28 inches Weight: 6oz. Long battery life - up to 10 hrs CW Generates a Pulsed signal foroptical fiber identification Center Wavelength: 1310nm Hand Held Lightweight  Caution! Caution! Caution! Extreme caution must be exercised when operating the BOLT-NL. Lasers such as the ones in the OWL BOLT-NL produce intense beams of laser light that are harmful to the eye. Exposure to such energy can cause serious retina damage, and prolonged exposure can cause blindness. TO ENSURE YOUR SAFETY: NEVER LOOK INTO A LIGHT SOURCE OR THE END OF AN OPTICAL FIBER THAT MAY BE  ENERGIZED BY A SOURCE! Product manuals come in PDF format on CD. Adobe Acrobat ReaderTM is required to view these documents.
