Instrumentation
5 mm operating distance
• Weak Optical Signal Detection
1554.97 nm Athermal Package FBG, 20 Ghz FWHM 980/1550 nm WDM The DFB TO56 lasers areFBG 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.
