Abstract We describe staircase codes, a new class of error-control codes suitable for high-speed optical communications. One sample design, targeted at 100Gb/s optical transport networks, yields an ITU-T G.709-compatible staircase code with rate R=239/255 for which FPGA-based simulation results exhibit a net coding gain (NCG) of 9.41 dB at an output error rate of 10^{-15}, an improvement of 0.42 dB relative to the best code from the ITU-T G.975.1 recommendation. An error floor analysis shows that this code has an error floor below 10^{-20}. These codes can be exploited in higher-order modulation schemes incorporating signal shaping, to achieve reliable communication near the estimated capacity of fiber channels. For example, one design yields a practically achievable spectral efficiency within 0.62 bits/s/Hz of the estimated capacity of a long-haul fiber channel having a length of 2000 km.

Kschischang is a Professor of Electrical and Computer Engineering at the University of Toronto, where he holds the Tier I Canada Research Chair in Communication Algorithms. His research interests are focused primarily on the area of channel coding techniques, applied to wireline, wireless and optical communication systems and networks. In 2010 he was awarded the Killam Research Fellowship by the Canada Council for the Arts. Jointly with Ralf Koetter he received the 2010 Communications Society and Information Theory Society Joint Paper Award. He is a Fellow of IEEE, and served as the 2010 President of the IEEE Information Theory Society.
