Intel has improved the situation somewhat: Thunderbolt 3 will support passive cabling up to two meters with bandwidth of up to 20Gbps, 40Gbps active copper cables for full 40Gbps connectivity (again, up to two meters long), and 40Gbps optical cables arriving in 2016, with lengths of up to 60 meters.
USB 3.1 was finalized in 2014, when maximum transfer speeds doubled from 625 MBps to 1,250 (matching Thunderbolt). Maximum power output also increased from 10 to 100 watts and a new reversible C type plug was introduced. These upgrades to the specification were entitled USB 3.1 rather than USB 4.0.
