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.

DESCRIPTION

Notes:

1. Available for DWDM based on ITU-T recommendations. please refer to Ordering Information.

2. Polarization state of LD is aligned parallel to the slow axis.
