Wide band optical fiber amplifier

摘要

Disclosed is a wide band optical fiber amplifier for amplifying C and L-band optical signal components having an economical configuration, high amplification efficiency while exhibiting a low noise figure. The present invention relates to optical communication systems, and more particularly to an optical fiber amplifier disposed between an optical transmission block and an optical receiver block in an optical communication system. The fiber amplifier may be erbium-doped <IMAGE>
