A Two-Way Optical Loss Test set (OLTS) that's perfect for medium to ultra high fiber count loss and length testing applications on single-mode fiber at 1310 and 1550 nm. A pair of these compact instruments set new standards of productivity, accuracy, and ease of use. The 650 nm VisiTester feature mixes a VFL in with the test signal during Autotest. In addition to operating as a typical VFL, it gives positive visual identification of a fiber to be connected for loss testing.

In addition to operating as a typical VFL, it gives positive visual identification of a fiber to be connected for loss testing.
Each fiber needs just one test hook-up and one key press for a complete bidirectional loss test, eliminating administration, training and test errors. Testing is accurate and can take only 5 seconds, direct onto flexible standards-compliant Tier 1 certification reports.
A pair of instruments both display bi-directional loss, in real time, with no need to specify master and slave instruments. A single instrument can also be used as a stand-alone light source and power meter, or tone generator and detector.
