Description
The D2547P-Type DFB laser module is designed for
use with an external lithium niobate modulator and
also in applications where high power (20 mW) is
required.
The laser comes packaged in an industry-standard
14-pin butterfly module with a polarization-maintain-
ing fiber pigtail.
Temperature-stabilized with a thermoelectric cooler
(TEC) and thermistor, the package is available in C
and L band ITU-T grid wavelengths on a 100 GHz
spacing plan.
D2547P does not contain a wavelength locker, which
is not needed for high-reliability operation in
100GHz-spaced applications. For a 20 mW CW laser
butterfly version with integrated wavelength locker
and available on a 50 GHz grid, refer to the compan-
ion product data sheet for D3587P.
Featuring wavelength selection to the DWDM ITU-T grid, the
D2547P Laser Modules are ideally suited for use with external
lithium niobate modulators, and in high-power (20 mW) appli-
cations.
