Wavelength-Selected High-Power D2587P-Type (with
Wavelength Locker)/D2547P-Type Isolated DFB Laser Modules
Applications
s Telecommunications:
— Dense WDM
— SONET/SDH OC-192/STM-64
— Extended and ultralong reach
— Undersea systems
s Digital video
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) appli-
cations.
Features
s High-performance, multiquantum-well (MQW),
distributed-feedback (DFB) laser
s D2587P-Type is offered on 50 GHz ITU grid
wavelengths ranging from 1528.77 nm—
1610.06 nm
s D2547P-Type is offered on 100 GHz ITU grid
wavelengths ranging from 1528.77 nm—
1610.06 nm
s Polarization-maintaining fiber pigtail
s For use with lithium niobate modulators
s High optical power (20 mW, CW)
s Hermetic, 14-pin package
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.
