NEC's CW InGaAsP MQW DFB
LASER DIODE MODULE NX8562
FOR DWDM APPLICATIONS SERIES
(20 mW MIN)
FEATURES
• 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

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.
The device is available for Dense Wavelength Division Multi-
plexing (DWDM) wavelengths based on ITU-T recommenda-
tions, enabling a wide range of applications.
