One of the
best features of USB is
its backwards compatibility, but as the years roll by, some aspects of that
compatibility end up being a bit of a disadvantage. For example, the connection
design. It hasn’t changed so as to ensure compatibility, but that has meant the
size stayed the same as has the fact it only fits into a USB port one way.
That is
going to change, though, and with the introduction of the USB 3.1
specification, we are set to get a brand new plug. It’s called the Type-C connector and improves upon the design in two
ways. Firstly, it’s going to get smaller, to the point where it’s similar in
size to the existing Micro
USB plug. Secondly, the new plug will be reversible, meaning it
doesn’t matter which way around it is when you slide it into a port.
The update
to USB 3.1 was already looking like a great revision. Data transfer rates are
being increased
to 10Gbps, and power output will already be increased
to 100 watts meaning you can ditch the power cable for compatible
devices. Now we’ve got a smaller cable to look forward to, which will also mean
the ports can shrink as well as accessories such as USB hubs.
One thing
the USB Implementers Forum must ensure, though, is that USB doesn’t lose its
resilience. A smaller plug needs to remain as strong and stable when plugged
in. If they damage easily or fall out with the lightest of knocks, then it will
be a step backwards.
We have yet
to see what the new Type C connector will look like, but with USB 3.1 expected
to be available next year, it shouldn’t be too long before examples of the new
cables and plugs start appearing. Also, don’t forget that backwards
compatibility is being retained. Therefore, we’re going to have a new USB
port adapter coming to market so these new cables fit old ports and old cables
fit new ones.
