  • Abstract
    Presents measurements of crosstalk penalties in a two-channel ASK system using 1.55 μm DFB lasers and a semiconductor laser amplifier. The amplifier was operated well below gain saturation. No additional receiver sensitivity penalty due to the amplifier was observed for single channel operation. However, the additional crosstalk in the amplifier required at 10% increase of the channel spacing compared to the spacing in the nonamplifier system
