FOLS-202 Handheld Fiber Optical Light Source (850/1300nm) with 2.5mm FC/SC Connector

FOLS-202 optical light source is a fiber optic tester with exquisite appearance and ergonomic design. It provides 850nm and 1300nm dual-wavelength laser output for multimode 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.
