An Optical Loss Test Set used to test power, loss, continuity and faults on single mode fiber with an APC connector at 1310 / 1550 / 1625 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.
