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.
