Description
The D2587P-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 use of an internal wavelength locker greatly
enhances long-term reliability and reduces chirp and
mode dispersion when used in conjunction with LN
modulators at OC-192 data rates.
A companion device, the D2547P high-power DFB
laser module, is also designed for use with a lithium
niobate external modulator, but without the use of an
internal wavelength locker.
