Abstract

The capacity of transoceanic optical cable systems is going to exceed lOOGbit/s in the next year [l], such as the Pacific Crossing-1(PC-1), Japan-U.S. Cable System, and TAT-14. The key to these advances is the presence of undersea-qualifed 980nm pump laser modules, which allow us to reduce the noise figure of erbium-doped fiber amplifiers in repeaters significantly compared with conventional 1480nm pumping [2]. In fact, the use of 980nm pump lasers in submarine repeaters has been a dream of for system suppliers for the past l0years. However, because so-called catastrophic optical damage occurring at the facet of GaAs-based laser diodes (LDs), obtainable reliability has been far away from the qualification level for submarine applications requiring 27 years of operation.
