Cisco Optics Podcast Episode 1
How did we go from 1G to 400G? The history of pluggable optics, a conversation with Ray Nering, part 1 of 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 first episode I start a 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. This is the first part of a four-episode conversation with Ray. In this episode we start at the beginning, with GBIC and SFP. He also talks about why pluggables were needed when they started and a whole bunch more.

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.
