LASER DIODE
NX8571 Series
1 550 nm CW LIGHT SOURCE
InGaAsP MQW-DFB LASER DIODE MODULE
WITH WAVELENGTH MONITOR
DESCRIPTION
The NX8571 Series is a 1 550 nm Multiple Quantum Well (MQW)
structured Distributed Feed-Back (DFB) laser diode module with wavelength
monitor function.
This device is temperature tunable over 4 × 50 GHz
channels. Available at both C-band (1530.334 to 1565.087 nm) and L-band
(1565.496 to 1608.760 nm) ITU-T grid wavelengths.
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)
• Optical output power: Pf = 10 mW MIN.
• Available for DWDM wavelengths based on ITU-T recommendations
(50 GHz grid)
• 4-channel wavelength tunable capability for 50 GHz-spacing
(NX8571S××××D)
• Internal thermo-electric cooler and isolator
• Hermetically sealed 14-pin butterfly package
• Polarization maintain fiber pigtail
Document No. PL10136EJ03V0DS (3rd edition)

Subject: Compliance with EU Directives
CEL certifies, to its knowledge, that semiconductor and laser products detailed below are compliant
with the requirements of European Union (EU) Directive 2002/95/EC Restriction on Use of Hazardous
Substances in electrical and electronic equipment (RoHS) and the requirements of EU Directive
2003/11/EC Restriction on Penta and Octa BDE.
CEL Pb-free products have the same base part number with a suffix added. The suffix –A indicates
that the device is Pb-free. The –AZ suffix is used to designate devices containing Pb which are
exempted from the requirement of RoHS directive (*). In all cases the devices have Pb-free terminals.
All devices with these suffixes meet the requirements of the RoHS directive.
This status is based on CEL’s understanding of the EU Directives and knowledge of the materials that
go into its products as of the date of disclosure of this information.
