USB 3.0 – SuperSpeed connections
The most common USB 3.0 plug types
Under the name "Super Speed" the new USB Version 3.0 has now become
established as the successor to the previously widespread USB 2.0 stan-
dard. The essential advantages of the new USB standard include a high
data transfer rate and an optimised power supply.
In contrast to the USB 2.0 standard ("High Speed") with transfer rates of 480
Mbit/sec, as "Super Speed", USB 3.0 has a transfer rate of 5 Gbit/sec i
n full
duplex mode and therefore a tenfold increase in transfer rate compared
with USB 2.0.
As with conventional USB cables, the power supply to peripheral devices
can be made via the USB cable. However, the maximum current has been
increased from 500 mA to 900 mA.
Because of the additional pair of conductors in the USB 3.0 cable, the plugs
are also different to conventional USB plugs.
The Type A plugs h
ave the same structure, but a wider contact level with
five adjacent contacts behind the contact level of the 2.0 plug. These con-
tacts are only activated if the A plug is plugged in as far as the stop.
With the type B plug, the difference can be seen from the outside. This has
an upper section above the USB 2.0 plug. This upper section accommodates
the five additional contacts for USB 3.0.
