Having been around since the mid-1990s, the Universal Serial Bus (USB) interface is one of the most successful interfaces in the history of the computer hardware. Billions of PCs and PC peripherals—such as the mouse, the keyboard, webcams, and many others—have utilized USB technology to provide reliable connections, data communication, and power charging. It has even started to support video output with the latest USB 3.1 technology, which will continue the trend of success and popularity that USB is known for by achieving 20 times greater data transfer rate while also retaining its well-known ease of use.
Unlike other data buses (FireWire, Ethernet, HDMI), USB connections are direct. The two major types of connectors, Type A and Type B—each with their own distinct shapes—are designed to distinguish the connector end to the host (downstream facing port) and to the device (upstream facing port). The A type end is in one standard form factor, whereas the B type connector varies between regular, mini, or micro formats as necessary for slim or small form factor device designs. The most recently introduced USB Type C connector can connect to host and device end,as a means of possibly replacing various A and B connectors in the future.
Released in April 2000, the USB 2.0 specification increased the USB maximum data rate to 480 Mb/s, also known as High Speed USB data rate, in addition to the USB 1.x Full Speed data rate of 12 Mb/s. Despite the later USB generations, until today USB 2.0 still remains the most popular USB interface due to its low cost advantage and implementation easiness.
As the technology advanced and market grew, some important features of USB technology, such as Mini USB and Micro USB connector, USB On-The-Go, Battery Charging and Power Delivery was defined and included into USB 2.0 standard package.
First published in 2008, USB 3.0 offers the so called Super Speed data transmission speed up to 5 Gbps/s, which is over 10 times faster than High Speed USB2.0 (480 Mbps/sec). USB 3.0 significantly increases the data transfer throughput, power efficiency, and is backwards compatible with USB 2.0.
With the ten times faster data transfer rate and improved power delivery, more industrial applications started to adopt USB 3.0 interface, such as high speed data transfer, medical and automation imaging sensor, video conference and surveillance security cameras, etc.
Newnex has been actively participating in USB 3.0 technology development and leading the USB market by introducing a full line of innovative products.
Different from coexistence of USB 2.0 and 3.0, USB 3.1, first released in 2013, is to replace the USB 3.0 standard. The USB 3.1 standard came with two data transfer rate, 5Gbps SuperSpeed, also referred to as USB 3.1 Gen 1 and introduced a faster transfer rate called SuperSpeed 10 Gbps or SuperSpeed Plus, which increase the data signaling rate to 10 Gbps double the 5Gbps SuperSpeed, and reduced line encoding overhead to 3% by changing the encoding scheme to 128b/132b. USB 3.1 is designed to be backward compatible to all previous USB generations, USB 2.0 and 3.0.
Along with the USB 3.1 specification, a new type of USB connector end, USB C, was introduced to best support the USB 3.1 Gen 2 data rate and offered reversible plug orientation, 100W maximum PD (Power Delivery) standard and display alternate mode support. A full-featured Type-C male to male cable is also able to be reversible on host to device direction.
With the advantages of true peer-to-peer connectivity and high efficiency rates, IEEE 1394 (FireWire) is a widely adopted interface. Currently, 1394 is used in mass-market computer, entertainment, and professional products, as well as in a wide range of specialty applications such as music, defense, aerospace, industry, and robotics. There have been over one billion 1394 ports shipped with PCs and peripherals worldwide.
As one of the first companies to receive the 1394a cable compliance logo, Newnex has been a leading developer of the 1394 standard, not only authoring the 1394a cable and connector compliance specifications but also contributing many 1394 white papers and other technical documents. Newnex continues to lead the 1394 market in long haul repeaters through patented technologies and innovative solutions. The company has successfully introduced the world's first 1394b optical repeater, the FireNEX800™. Newnex is the only company in the world with solutions to extend 1394 signals over long distances for all technically viable media such as optical fiber, plastic fiber, category cables and coax cables.
S1600 1394b products are now on the market. S1600 refers to a data transfer rate of 1,600 Mbps, which is twice as fast as S800, the previous top speed for 1394. Current high quality 1394b Newnex cables and connectors are compatible with S1600 products.
Ethernet is one of the most popular networking protocols used today, currently implemented in 85% of the world's LAN connected PCs and workstations. Gigabit Ethernet has become the leading technology in machine vision applications. The success of Gigabit Ethernet is due to its high bandwidth (1000Mbps), uncompressed data transfer, low cost of integration and ability to travel over extended distances of up to 100 meters. Determined to advance the applicable uses and flexibility of Gigabit Ethernet, Newnex has developed Snap-On Gigabit Ethernet plugs with patent pending technology. Newnex' innovative Snap-On Gigabit Ethernet plugs are equipped with industry standard locking screws for extremely easy on-site cable termination. From multi-million cycle high-flex Gigabit Ethernet cabling to custom designed connectors, Newnex will continue to provide quality connectivity products for the Gigabit Ethernet Vision market.
