DFB fiber source

DFB fiber source

The H�A DFB laser is available at 1550 or 1310 nm or at other center wavelengths ranging from 1535 to 1560.5 nm for dense WDM applications. The center wavelength can be temperature tuned to ۫.8 nm. The laser can be modulated with digital ac- or dc-coupled or an analog ac-coupled signal and provides powers u¥to 1.3 mW. It can be used as part of a lightwave digital stimulus-response test system at data rates u¥to 2.5 Gbit/s and can also be used as a reference transmitter for manufacturing applications that require a SDH or SONET compatible source.
