Abstract

Evolution of optical amplifier (OA) technology based on Er-doped fiber amplifiers (EDFA), which has made remarkable progress in recent years, has brought about a big impact to long-haul optical fiber transmission systems.[1]-[3] One of the largest benefits of EDFA technology would be gifted to the area of undersea cable systems highlighted by TPC-5 cable network (CN) and TAT-12 &13, both of which are planned to be completed in 1996.[4][5] From the engineering point of view, how to achieve the required performance and how to maintain the performance for the design life are important. This paper outlines these issues by showing recent development results. [6]
