LASER DIODE
NX8571SA
1 550 nm CW LIGHT SOURCE
InGaAsP MQW-DFB LASER DIODE MODULE
WITH WAVELENGTH MONITOR
DESCRIPTION
The NX8571SA is a 1 550 nm Multiple Quantum Well (MQW) structured Distributed Feed-Back (DFB) laser diode
module with wavelength monitor function.
This device is designed as CW light source and ideal for transmission systems in which external modulators are
used.
FEATURES
• Wavelength monitor function (Etalon Filter, Wavelength monitor PD)
• Output power
P
f
= 10 mW MIN.
• Available for DWDM wavelengths based on ITU-T recommendations
(100 GHz grid, refer to ORDERING INFORMATION)
• Internal thermo-electric cooler and isolator
• Hermetically sealed 14-pin butterfly package
• Polarization maintain fiber pigtail
