39.4 Gb/s Data Transmission over 24.4 meters of Coaxial Cable using Duobinary Signaling
15 June 2008
We demonstrate, for the first time, transmission of 39.4 Gb/s data over a 24.4-meter long 5.2 mm diameter coaxial cable with SMA connectors using electrical duobinary signaling. A custom Indium Phosphide (InP) duobinary-to-binary converter integrated circuit has been designed and is used in conjunction with a clock recovery circuit to achieve a bit error rate better than 3x10-12 with a 215-1 bit sequence.
