PH Optical Light Sources are light sources with combination of various wavelengths with a fixed output power of –5dBm.

- 1310/1550nm,

- 310/1490/1550nm,

- 850/1300/1310/1550nm

-1310/1490/1550/1625nm

The OLS transmits an encrypted wavelength synchronization tone, enabling the OPM-C Series Optical Power Meters to automatically detect the wavelength of PH OLS. The features increase the operation efficiency and decrease the potential human errors while switching the test wavelength.

The PH OLS Series offers excellent stability and portability for accurate fiber optic optical power and insertion loss testing. The OLS provides stable laser power at dual, tri and quad wavelengths.
