ABSTRACT:
The invention is related to an optical amplifier connected to a pump laser with lengths of fibers and isolators between the lengths of fibers. The invention is also related to a transmission system using this amplifier and in addition the invention gives also a rule to optimize the position of isolators in a amplifier.
