Abstract :
The monitoring and fault location of long chains of optical amplifiers such as will be deployed in undersea cable systems is an important design consideration. The Letter describes two methods which have been proposed and one which has been evaluated on the authors´ test bed simulator of 3100 km with OAs spaced at 45 km and operating at 5 Gbit/s.
