Instrumentation

The DFB laser’s operating temperature and drive current are precisely monitored by a micro-controller to ensure constant output power and emission wavelength stability

1554.97 nm Athermal Package FBG, 20 Ghz FWHM 980/1550 nm WDM • Weak Optical Signal DetectionFBG is the key component that acts as a rejection filter in telecommunications. The center wavelength of FBG is very sensitive to changes of temperature or strain. The package is used by the technology of temperature compensation to make the wavelength very stable.
