An Optical Loss Tester used to test power, insertion loss, continuity and faults on multimode fiber optic systems at 850 / 1300 nm. In a small package, it provides a powerful solution to improve test flexibility and productivity.
The 650 nm VFL 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.
