Descriptions
FOL15DCWx-Axx-Wxxxx series of DFB laser module is designed for probe light sources,
supervisory channel. The polarization maintaining fiber pigtail enables to directly connect a
modulator without polarization control. The polarization state of output laser beam is
maintained to a consistent orientation. The module is housed in an industry standard
hermetically sealed 14-pin butterfly package, which contains optical isolator, thermoelectric
cooler, power monitor photodiode. A particular wavelength selection is available from a very
wide wavelength range between 1490nm and 1625nm.
