100G optical transport based on polarization and/or subcarrier multiplexed modulation formats

Future optical transport systems at 100G and beyond will inevitably make use of advanced modulation formats and digital signal processing techniques. In this contribution, we discuss 100G techniques based on the combination of subcarrier multiplexing, and/or polarization multiplexing with various phase shifted keyed (xPSK) modulation formats. Experimental results from a series of lab verifications and field trials demonstrate that these techniques, together with coherent detection and advanced DSP, are critical for high performance 100G transponder development.
