KI 23400 & 27400 Handheld Two-Way Loss / Length Test Set

An Optical Loss Test set (OLTS) with length measurement that's perfect for high volume loss & length testing applications. A pair of these instruments set new standards of productivity, accuracy and ease of use.

With just one test hook-up and one key press per fiber for bidirectional testing, the same test method can be used for all fibers in a network, eliminating complex layers of administration and test errors. Testing is accurate and can take only 5 seconds, direct onto a final report. 

A pair of instruments both display length as well as bi-directional and average loss in real time, with no need to specify master/slave instruments. A single instrument can be used as a stand-alone light source & power meter, or tone generator / detector. 

  • SM, MM, quad & other wavelengths.
  • Real-time Autotest loss and length testing on one fiber
  • Real time Pass / Fail display
  • 10,000 fiber memory and USB Interface
  • KITS™ reporting software for acquisition and reporting
  • Autotest power meter
