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.
Featuring wavelength selection and locking capabilities, the D2587P Laser Module is ideally suited for use with external lithium niobate modulators, and in high-power (20 mW) applications.

Principles of Operation (Controlled Wavelength)
The single-channel, wavelength-selected DFB (ILM) package contains internal wavelength-discriminating optics, i.
e.
, two etalons and associated photodiodes.
The output consists of analog signals suitable for controlling the electrical current of the thermoelectric cooler (TEC) and the DFB laser.
