Description
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. This is the third part of a four-episode conversation with Ray. In this episode we get into 100Gb pluggables and then the QSFP-DD form factor.
