Fiber Quick Check

See the light with this high-intensity, low-cost fiber light source.


Please call 877-877-2269 for a replacement product or part.
1 Year Double Diamond™ Warranty (Standard)

Product Features

  • Easy to use and see. It removes the guesswork when tracing fiber cable.
  • Use with all types of fiber: ST, SC-, FC-, RSD-, and FSD-type cables with 2.5-mm ferrules.
  • Choose from two light modes—steady light signal or exclusive MICROPULSE™ signal pulsing.
  • Includes one 9-volt battery.
  • LED is safe to view directly.


  • MICROPULSE mode produces an extremely bright red source LED (660 nm, 1400 mcd) to easily distinguish a particular fiber, making it great for bundles in wiring closets.
  • Steady light mode is perfect for testing cable spools.

    Tracing fiber cable in a building or on a spool will never be a guessing game again. The affordable Fiber Quick Check produces a high-intensity light far brighter than that from an incandescent source, making cable identification a sure thing. And the light source is safe to view directly—no worries about damaging laser light.

    The Fiber Quick Check features MICROPULSE technology, which produces an extremely bright red source LED (660 nm, 1400 mcd). Use the pulse mode to make it easier to distinguish a particular fiber, especially in a bundle in the wiring closet. Or use a steady light for testing a spool of cable. You can use the Fiber Quick Check with all types of fiber cable. It features a multiuse coupler for connections to ST, SC, SMA, FC, RSD, and FSD-type cable with 2.5-mm ferrules.
