USB Type-C based USB 3.1 is designed to give life to a universal connector for both data exchange and device power.
The final specifications of the standard USB Type-C were published seven months ago, but so far the only product on the market to adopt the new serial port was the Nokia N1, Android tablet only available in China. Its spread will surely increase with the announcement of new devices by the world’s leading manufacturers: Apple with the MacBook and Google with the Chromebook Pixel have already established that USB Type-C is the standard of the future.
USB Type-C: A new standard is born
With the development, approval and arrival on the market of the first USB Type-C connectors comes a new standard destined to get wide quickly on the market. The advantages of the new connector are indeed considerable, in every view: The standard meets the needs of a new market, in which devices that can interconnect are many more and in which the role of tablet and smartphone goes beyond that of simple compendium to desktop systems. In this new market that is delineing, the roles of the devices in the hands of users have changed the respective balances and the needs (of charging on one side, of interchange of data on the other) have mutated.
The specifications are described in a special official document (. zip, 47.5 MB) written by the USB C VS USB 3.0 promoter Group, which describes both the physical characteristics and the details of connectivity, both in connection with the connectors and the cables. These specifications are based on the implementations made by the producers, so that the standard can be adopted in a uniform and efficient way by becoming a living rib of the new computer ecosystem that is to be born.
USB Type-C: Reversible
The USB Type-C standard adheres to USB 3.1 specifications, which introduces several improvements over version 3.0. The USB Type-C port in the new MacBook allows you to achieve a maximum transfer rate of 5 Gbps. It is spoken in this case of USB mode 3.1 Gen1, also known as SuperSpeed. The USB 3.1 Gen2 mode, however, offers a maximum speed of 10 Gbps (SuperSpeed +). The peculiarity of USB Type-C is its reversibility or symmetry. The user can immediately insert the cable into the door without having to go to attempts or scrutinize the connector carefully before finding the right insertion direction.
USB Type-C: Backward compatible
This feature has a negative side. The standard is backward compatible with USB 3.0 and USB 2.0, but to connect the old peripherals to the USB type-C ports you need to purchase an adapter or cable type-c/Type-A and type-c/Type-B. Clearly, the safety of backward compatibility is not a guarantee for the exploitation of all the peculiarities of the new connector: only a USB Type-C device will be able to enjoy all the advantages of the new standard when connected to another USB type-C device, so the other adapters do not do without ensuring the minimum functionality.
But this is the only “flaw” of the new version: As Apple has shown (eliminating all ports from the MacBook), the standard allows not only to connect USB, VGA, HDMI and DisplayPort devices (with appropriate adapters), but also to use only one cable to power all devices. The label “Standard” is therefore wide-ranging: for how it was studied, the new USB Type-C will replace most of the current connectors, reducing the amount (and therefore the cost of implementation), the variety of cables needed and the convenience of use by the end user. The designation of “universal connector” is therefore not a mere poetic license: this is the ambition of the new standard and the reason that stimulated the development.
USB Type-C: to power any device
USB 3.1 USB power Delivery 2.0 specifications include two new 12-and 20-Volt profiles for a maximum power of 100 watts. Monitors, printers, and other devices can be powered directly from your notebook or PC, as well as smartphones and tablets can be recharged from any compatible device. The operation is bidirectional, so a monitor could power a notebook and the management of the increasingly numerous batteries in use becomes easier in every situation.
The debut of USB Type-C in the Apple world could be the flywheel to the explosion of the new standard. The new type of connector is in fact the protagonist on the new MacBook announced in March 2015 (see images), in which the connector is one of the first elements to have allowed a greater subtlety of the case for a smaller weight and a sharper profile. The novelty, however, requires Apple to have the necessary attention to all devices and peripherals that

The novelty, however, requires Apple to have the necessary attention to all devices and peripherals that still do not contemplate the new standard: a series of cables and docks were immediately made available, with prices ranging from 19 to 89 euros, in order to immediately meet the needs dictated by the new standard.
