SANTEC OPTICAL COMPONENTS
Optical Wavelength Locker
OWL-10
Wavelength Locker OWL Series
Dimensions
Typical Configuration
The OWL -10 wavelength locker enables the wavelength
of DWDM transmitters to be monitored and stabilized.
Santec's unique single filter differential method is
utilized to achieve the highest wavelength accuracy and
reliability of any commercial wavelength locking device.
The OWL-10 has become the industry standard and is
indispensable in 50GHz and 100GHz DWDM systems.
