DESCRIPTION
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.
