<P>PROBLEM TO BE SOLVED: To provide an optical amplifier for transmitting / receiving control signals without causing crosstalk and flexibly controlling many optical amplifier units in a unified way, and to provide an optical amplification relay transmission system employing the optical amplifier. <P>SOLUTION: The optical amplifier includes a communication unit and a plurality of the optical amplifier units connected thereto. The optical amplifier is characterized in that a unique identification code is decided for each optical amplifier unit so as to distinguishingly controlling a plurality of the interpolation amplifier units. Further, using the optical amplifier configures the optical amplifier transmission system. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
