Descriptions

FOL15DCWD 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 14-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 als o available.
