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

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.
