Impact of Erbium-doped amplifiers on optical communication systems

Sadakuni Shimada

This article outlines the recent studies on optical amplifiers and compares the features of fiber amplifiers with those of other optical amplifiers. The impact of this new amplifier technology is then discussed and the future possibility of communication systems with optical amplifiers is assessed. Systems applications are described using the effectiveness of these fiber amplifiers—long repeater spacing systems, undersea systems, soliton transmission, and subscriber loop systems. A compact fiber amplifier for general use is also mentioned.
