400Gb/s and Beyond with Kim Roberts

New optical networks require flexibility and agility from network elements, especially from coherent transceivers. To achieve capacities of 400Gb/s and more, coherent transceivers operate at higher baud rates. This is made possible with higher bandwidth components using new electro optic technologies implemented with indium phosphide (InP) and silicon photonics (SiP). New digital signal processing algorithms are implemented in 150 trillion-operations-per-second CMOS ASICs.
About our Speaker
Kim Roberts is a passionate evangelist of new optical and high-capacity packet technologies and holds the distinction of being Ciena Corporation’s (previously Nortel’s) leading inventor. Kim holds more than 140 patents with many more pending.
Kim has been a major force in the field of digital signal processing (DSP) for optical transmission systems, and played a key role in virtually every optical innovation developed by Nortel. These range from the Superdecoder (the use of electronic signal processing of optical signals), the OC-48 regenerator, and the original OC-192 (10-Gbit/s) system, to terrestrial optical amplifiers and the revolutionary eDCO pre-compensating transmitter. Building on these breakthroughs, Kim helped develop the DSP-assisted coherent transceivers that are at the heart of the world’s first coherent 40, 100 and 200 Gb/s optical systems. Today Kim is Vice President at Ciena, leading an R&D team focused on pushing the optical boundaries even further in terms of speed, distance and cost with the Wave Logic Ai transceiver.
In recognition of the pioneering role he has played in the industry, Kim was named a Nortel Fellow and he received the Outstanding Engineer medal in 2008 from IEEE Canada. Kim routinely shares his expertise with the research and education fields, and is in high demand as a speaker and committee member with industry organisations.
Kim holds a Bachelor degree in Electrical Engineering with an emphasis on mathematics, and a Master degree in Electrical Engineering with the topic of processing of brain signals, both from the University of British Columbia.
