LASER DIODE
NX8571SCxxxQ-BA
1 550 nm CW LIGHT SOURCE
InGaAsP MQW-DFB LASER DIODE MODULE
WITH WAVELENGTH MONITOR
DESCRIPTION
The NX8571SCxxxQ-BA 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 8 × 50 GHz
channels. Available at both C-band (1 530.334 to 1 565.087 nm) and L-band
(1 565.496 to 1 608.760 nm) ITU-T grid wavelengths.
This device is designed as CW light source and ideal for transmission
systems in which external modulators are used.

When the product(s) listed in this document is subject to any applicable import or export control laws and regulation of the authority
having competent jurisdiction, such product(s) shall not be imported or exported without obtaining the import or export license.
•
The information in this document is current as of September, 2005. The information is subject to
change without notice. For actual design-in, refer to the latest publications of NEC's data sheets or
data books, etc., for the most up-to-date specifications of NEC semiconductor products. Not all
products and/or types are available in every country. Please check with an NEC sales representative
for availability and additional information.

No part of this document may be copied or reproduced in any form or by any means without prior
written consent of NEC. NEC assumes no responsibility for any errors that may appear in this document.
NEC does not assume any liability for infringement of patents, copyrights or other intellectual property rights of
third parties by or arising from the use of NEC semiconductor products listed in this document or any other
liability arising from the use of such products. No license, express, implied or otherwise, is granted under any

Descriptions of circuits, software and other related information in this document are provided for illustrative
purposes in semiconductor product operation and application examples. The incorporation of these
circuits, software and information in the design of customer's equipment shall be done under the full
responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third
parties arising from the use of these circuits, software and information.
While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers
agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize
risks of damage to property or injury (including death) to persons arising from defects in NEC
semiconductor products, customers must incorporate sufficient safety measures in their design, such as
redundancy, fire-containment, and anti-failure features.
NEC semiconductor products are classified into the following three quality grades:
"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products
developed based on a customer-designated "quality assurance program" for a specific application. The
recommended applications of a semiconductor product depend on its quality grade, as indicated below.
Customers must check the quality grade of each semiconductor product before using it in a particular
application.
"Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio
and visual equipment, home electronic appliances, machine tools, personal electronic equipment
and industrial robots
"Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
"Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems and medical equipment for life support, etc.
The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's
data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not
intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness
to support a given application.
(Note)
(1) "NEC" as used in this statement means NEC Corporation, NEC Compound Semiconductor Devices, Ltd.
and also includes its majority-owned subsidiaries.
(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for
NEC (as defined above).

CLASS lllb LASER PRODUCT
A laser beam is emitted from this diode during operation.
The laser beam, visible or invisible, directly or indirectly, may cause injury to the eye or loss of
eyesight.
Warning Laser Beam
Caution GaAs Products
• Do not look directly into the laser beam.
• Avoid exposure to the laser beam, any reflected or collimated beam.
This product uses gallium arsenide (GaAs).
GaAs vapor and powder are hazardous to human health if inhaled or ingested, so please observe
the following points.
• Follow related laws and ordinances when disposing of the product. If there are no applicable laws
and/or ordinances, dispose of the product as recommended below.
1. Commission a disposal company able to (with a license to) collect, transport and dispose of
materials that contain arsenic and other such industrial waste materials.
2. Exclude the product from general industrial waste and household garbage, and ensure that the
product is controlled (as industrial waste subject to special control) up until final disposal.
• Do not burn, destroy, cut, crush, or chemically dissolve the product.
• Do not lick the product or in any way allow it to enter the mouth.
A glass-fiber is attached on the product. Handle with care.
Caution Optical Fiber
• When the fiber is broken or damaged, handle carefully to avoid injury from the damaged part
or fragments.
