FOLS-201 Fiber Optical Light Source

FOLS-201 optical light source is a fiber optic tester with exquisite appearance and ergonomic design. It provides 1310nm and 1550nm dual-wavelength laser output for singlemode fiber measurements, which is mainly used in FTTx networks and fiber network testing. When combine with a power meter, the instrument is called an Optical Loss Test Set, or OLTS, typically used to measure optical power and end-to-end optical loss.
