Relying on high accuracy automatic power control (APC) and automatic temperature control (ATC) techniques, the DFB light sources deliver very stable output power in both short term and long term. These light sources can work at CW, internal modulate, and external modulate modes.
DFB laser outputs a narrow band, single longitudinal mode laser power. DFB laser light sources work at wavelength of 1310nm, 1550nm bands, CWDM channel and ITU DWDM channels.
