Introduction

The handheld optical light source is a fiber optic tester which can provide 

dual-wavelength laser output. It provides excellent power stability for FTTx networks  

and fiber network testing. When combine with a power meter, it offers a quick and 

accurate testing solution on both single mode and multimode fibers. The figures below
