THE ORDERING INFORMATION

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.

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.

DESCRIPTION

California Eastern Laboratories

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.
