Bidirectional Loss, Length, ORL Testers KI 23400 & 27400 Series

A Bidirectional Optical Loss Test set (OLTS) with optional length & ORL measurement that's perfect for ultra-high fiber count Tier 1 loss & length testing applications. A pair of compact instruments set new standards of productivity, accuracy, and ease of use.

Each fiber needs just one test hook-up and one key press for a complete bidirectional loss, length and ORL test, for both single-mode and multimode fiber, so the same test method can be used for all fibers in a network, eliminating administration, training, and test errors. Testing is accurate and can take only 5 seconds, direct onto a final standards compliant certification report. The Visitester option lights up the far end of the fiber to be tested.

A pair of testers both display length as well as bi-directional loss and optical return loss each end, in one hook-up, in real time, with no need to specify master/slave instruments. A single instrument can also be used as a stand-alone light source & power meter, ORL meter, VFL, or tone generator / detector. 

KI234x series instruments feature the optical return loss (ORL) test option, as well as having an ultra-stable source with zero warm-up time to specification.
