Optical Light Source

OLS Series


Product Overview

OLS Series Optical Light Sources are the light sources with combination of various wavelengths;
- 1310/1550nm,
- 310/1490/1550nm,
- 850/1300/1310/1550nm
with a fixed output power of -5dBm

The OLS transmits encrypted wavelength synchronization protocol, enabling the OPM-C Series Optical Power Meters to automatically detect the wavelength of OLS Series. The features increase the communication efficiency and decrease the potential for errors.

The OLS Series offers excellent stability and portability for accurate fiber optic testing. Single output port provides stable laser power at dual wavelengths. The compact unit operates in either continuous wave (CW) mode or modulated mode. It has a low battery alert reminder.
