Qualification-testing and field-reliability results for 980-nm pump lasers

Not Accessible

Abstract

To date, more than 4 million device hours of field operation have been accumulated by 980-nm pump lasers, operating on booster EDFAs installed by U.S. carriers for SONET OC48 systems. This quite large, and still rapidly increasing, database allows for a complete critical-reliability evaluation of high-power 980-nm devices, from accelerated testing to field results.
