How did we go from 1G to 400G? The history of pluggable optics, a conversation with Ray Nering 2/4

Have you ever wondered why pluggable optics exist? Have you ever wondered what acronyms like QSFP, LR4, FEC, and PAM4 actually mean? In this episode I continue my conversation with my colleague Ray Nering. He explains to me how a lot of these came to be, starting from the days of 1Gb GBIC all the way up to today's 400Gb QSFP-DD.Ê This is the second part of a four-episode conversation with Ray. In this episode we get into 10Gb pluggables and the drivers of next generation technology. Ð Pat Chou, Cisco Optics Product Manager Ray Nering is a colleague of mine in the Cisco Optics product management group and over the years has held senior management positions at other companies in the optics space, such as AT&T Microelectronics, Lucent, JDSU, Agere, Optium, and Lightwire.
