Abstract :
It is shown that residual facet reflectivity in travelling-wave semiconductor optical amplifiers causes cumulative pulse broadening and distortion, hence limiting the maximum number of amplifiers that may be reliably used in a local network. For a TDM network, closed-form expressions are derived for this number in terms of bit rate and amplifier and pulse parameters.
