NEC's CW InGaAsP

MQW DFB LASER DIODE MODULE

FOR DWDM APPLICATIONS (10 mW MIN)

NX8563

SERIES

FEATURES

DESCRIPTION

NEC's NX8563 Series are a 1550 nm Multiple Quantum Well

(MQW) structured Distributed Feed-Back (DFB) laser diode

with Polarization Maintain Fiber (PMF). This device is de-

signed as Continuous Wave (CW) light source and ideal for

optical transmission systems in which external modulators are

used.

• OUTPUT POWER:

Pf = 10 mW MIN

• INTERNAL THERMOELECTRIC COOLER AND ISOLATOR

• HERMETICALLY SEALED 14-PIN BUTTERFLY PACKAGE

• POLARIZATION MAINTAIN FIBER PIGTAIL

• AVAILABLE FOR DWDM WAVELENGTHS BASED ON

ITU-T RECOMMENDATIONS (100 GHz GRID) REFER TO

THE ORDERING INFORMATION

This device is available for Dense Wavelenght Division Multi-

plexing (DWDM) wave lengths based on ITU-T recommenda-

tions, enabling a wide range of applications.
