Experimental demonstration of net coding gain of 10.1 dB using 12.4 Gb/s block turbo code with 3-bit soft decision

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/.
