980-Type Ultrahigh
Reliability Pump Laser Module
Preliminary Data Sheet
April 1999
results for each 980-Type Pump Laser Module are then
examined to ensure that only the pump laser modules
that exhibit performance consistent with long-term sys-
tem operation are selected for product.
Each 980-Type is individually serialized for full trace-
ability and is shipped with the appropriate test data.
The 980-Type assembly, test, and certification facilities
have all passed the rigorous qualification process
required for all facilities that manufacture devices
employed in undersea applications. Also, on an ongo-
ing basis, small quantities of product from each manu-
facturing lot are retained and tested as part of a
surveillance program for undersea devices. Each sur-
veillance group is subjected to the complete spectrum
of environmental/mechanical stresses required during
the qualification process. The surveillance results are
reviewed and compiled so that long-term trends can be
studied. The reliability performance of the 980-Type
Pump Laser Module is a result of a rigorous qualifica-
tion process combined with an extensive and ongoing
surveillance program.
Description
(continued)
The 980-Type Pump Laser Module has been specifi-
cally designed for undersea optical amplified very high
capacity transmission systems that require long-term
life expectancy. The extremely stringent reliability
requirements imposed on the 980-Type (necessary to
achieve long-term system life) are accomplished
through careful design, exacting manufacture, and thor-
ough testing. The 980-Type qualification plan consists
of a basic set of electro-optic and mechanical tests
designed to confirm the performance and reliability of
the module over its projected service life under
assumed operating conditions. Custom designed,
extended qualification test programs can be developed
to focus on customer system requirements.
Based on the results of qualification testing, a certifica-
tion program has been developed to ensure the high-
reliability performance of the devices. Each 980-Type
device undergoes this certification process where the
performance parameters are measured before, during,
and after environmental stresses. The certification
