NEC's CW InGaAsP MQW DFB

LASER DIODE MODULE

FOR DWDM APPLICATIONS

(20 mW MIN)

NX8562

SERIES

FEATURES

DESCRIPTION

NEC's NX8562 Series are a 1550 nm Multiple Quatum Well

(MQW) Distributed Feed-Back (DFB) laser diode with Polar-

ization Maintain Fiber (PMF). This device is designed as a

Continuous Wave (CW) light source and is ideal for optical

transmission systems in which external modulators are used.

• AVAILABLE FOR DWDM WAVELENGTHS BASED ON

ITU-T RECOMMENDATIONS

(100 GHz grid) refer to the Ordering Information

• OUTPUT POWER:

Pf = 20 mW MIN

• INTERNAL THERMOELECTRIC COOLER AND ISOLATOR

• HERMETICALLY SEALED 14-PIN BUTTERFLY PACKAGE

• POLARIZATION MAINTAIN FIBER PIGTAIL

The device is available for Dense Wavelength Division Multi-

plexing (DWDM) wavelengths based on ITU-T recommenda-

tions, enabling a wide range of applications.
