"FC has had an accurate roadmap for over a decade, showing the past, present and future of the FC physical layer. The interface has been progressing since 1996 by doubling the data rate (FC) every few years and the roadmap shows the progression will continue far into the future.
The ANSI INCITS T11.2 Task Group (T11.2), the standards body that defines FC speeds, finished 64Gb FC in 2018. 64GFC runs 9% faster than 50GbE and has been defined for a Bit Error Ratio (BER) of 1E-15 that is 1,000 v better than Ethernet that has a 1W-12 BER. 64GFC products are expected to ship in 2020/2021..."
