1570nm Coaxial DFB Laser Diode

1570nm Coaxial DFB Laser Diode is fibre coupled with single mode optical fibre. CW output powers are wavelength dependent and lie between 2mW and 4mW. The distributed feedback cavity produces a linewidth of just 0.32nm, these laser diodes have a built in monitor photodiode and optical isolator. The SMF 28 optical output fibre can be terminated with SC/PC, FC/PC, SC/APC, or FC/APC connectors.
