Optical arrangement for amplifying WDM signals
摘要:
An amplification circuit for amplifying wavelength-division-multiplexed (WDM) optical signals in a fiber-optic network is presented. The amplification circuit amplifies WDM signals propagating simultaneously in both directions through a fiber-optic link with a single unidirectional optical amplifier.
