Descriptions
FOL15DCWA series of DFB laser module is designed for long haul DWDM applications with
external intensity modulator. 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 4-pin butterfly package, which contains optical isolator, thermoelectric
cooler, power monitor photodiode. Precise wavelength selection is available according to ITU-
T grid with 100GHz spaced wavelength allocation. 50GHz spacing is also available.
