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 also available.

Wavelength values are referenced to vacuum. 50GHz spacing is also available.
Other ITU wavelengths may be available. Please ask to the regional contacts.
Wavelength (λ) and ITU frequency (f) have a relationship of
λ[nm]
= 299792458 / f[THz] /1000.
FITEL code is expressed as a 5-digit integer rounded from 100 x f [THz].
