Kim Roberts has innovated in the areas of optical transmission and high capacity packet connections since 1984. His creations are at the heart of much of Ciena's (Formerly Nortel’s) optical transmission portfolio from the first OC-48 to the 40-400 Gb/s DSP- assisted coherent transceivers. He has been granted over 120 US patents while at labs in Edmonton, Harlow UK, and Ottawa. He was named a Nortel Fellow and received the Outstanding Engineer medal in 2008 from IEEE Canada.
