1550 nm InGaAsP MQW-DFB

LASER DIODE MODULE CW LIGHT

SOURCE FOR DWDM APPLICATIONS

NX8562LB

FEATURES

DESCRIPTION

The NX8562LB is a 1550 nm Multiple Quatum Well (MQW)

Distributed Feed-Back (DFB) laser diode with Polarization

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

ous Wave (CW) light source and is ideal for optical transmis-

sion 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.
