WebMar 28, 2003 · Abstract: Turbo FEC for 10 Gb/s optical transmission has been experimentally demonstrated, for the first time. Using a newly developed 3-bit soft decision LSI, a record coding gain was achieved with only 24.6% redundancy for an input BER of 1.98/spl times/10/sup -2/. WebThe signal-to-noise ratios of single-pulse and coded Raman optical time-domain reflectometry (ROTDR) are analytically modelled. It turns out that there is an upper limit of coding gain of ~9 dB imposed by amplified shot noise in coded ROTDR.
