Abstract
We have reported1−2 recently, successful transmission of bi-directional repeaterless transmission at 10-Gbit/s at the 1550-nm wavelength over both 150-km of dispersion-shifted fiber (DSF) and 120-km of regular single-mode fiber (SMF). In addition, we have also demonstrated3,4 that the bi-directional fiber transmission of up to six channels reduces four-wave mixing (FWM) degradation with efficient bandwidth utilization. Here, we describe transmission performance of two 10-Gbit/s 1550-nm repeatered channels over two spans of 120-km of DSF using a novel in-line bi-directional erbium amplifier repeater (BEAR).
