EXFO FOS-120 Fiber Optic Light Source

The FOS-120 is a low cost fiberoptic light source in a rugged hand-held format designed for both field and laboratory appllications. This unit offers an excellent performance/price ratio.

The FOS 120 is designed to generate a constant optical power and compensate for temperature changes. For example, to gnerate a CW signal of -18 dBM at 30 degrees celcius, the source will require more current from the battery than if the unit was operating at room temperature.

Main Features:

- Two optical power level settings: LO and HI

- 9 VDC alkaline battery with early low battery detection. A LO BAT indicator will warn you about 30min before power failure.

-Rugged weatherproof plastic case for field and lab applications.
