Abstract
A broadband light amplifier comprising a pair of signal transmission and amplification arms, one for carrying a short wavelength signal in a short optical wavelength band and another for carrying a longer wavelength signal in a longer optical wavelength band, an optical amplifier in each arm for amplifying a respective signal carried therein, and a wavelength division optical multiplexer for combining the amplified signals into a single optical fiber, the amplifier being devoid of a circulator.
