What is a USB Type-B cable and what is it for?
If you are looking for, need to buy or even have the curiosity to know what is the USB Type-B cable and what is it for, here you can check these answers.
It is difficult to imagine today’s modern life without electronic devices. Smartphones, tablets, printers, notebooks … in short, several of these devices can be present in your home. All of these devices have their own uses, so each one works in a unique way. However, there is something in common between most of these devices. We’re talking about cables. And here we will detail more what is the USB Type-B cable and what is it for.
USB (Universal Serial Bus) cables are ubiquitous in our lives. Almost all electronic devices require a special component (a USB cable), either for connection to other electronic devices or for charging itself, in the case of wireless devices.
As technology and devices continuously advance and evolve, so do the corresponding peripheral devices. The same trend of technological updating is observed in USB cables. Here we will analyze the USB type-B, what are its assignments, and how to differentiate it from UBS type A or type C.
Types of USB cables
To fully understand USB Type-B, we must first understand the various versions of the USB standard. The USB type refers to the physical shape and wiring of the ports and plugs, while the version indicates the speed and functionality of the complete interconnection system.
USB Type-A and Type-C
With a flat, rectangular shape, USB Type-A was the original design for the first USB standard. Type-A ports are usually on host devices, such as desktop computers, laptops, game consoles, keyboards, mice, flash drives, and media players; peripheral devices rarely use a Type-A port.
USB Type-C is newer, and you’ll find it on most new devices. It offers faster data transfer rates than previous USB versions. The biggest advantage of USB-C is that it is reversible and can be connected from both sides. For this reason, it is the new standard for mobile devices.
USB Cable Versions
USB versions include 1.1, 2.0, 3.0 and 3.1. USB 1.1 was the first USB version launched in 1998 and has a maximum speed of 12Mbps. In many cases, USB 1.1 works only at 1.2 Mbps and has become largely obsolete.
Launched in 2000, USB 2.0 has a maximum speed of 480 Mbps in Hi-Speed mode, or 12Mbps. It is compatible with previous versions of USB 1.1 and has a maximum output power of 2.5 V (1.8 A).
USB 3.0 was launched in 2008 and has a maximum speed of 5 Gbps in SuperSpeed mode and is usually blue. It is backward compatible with USB 2.0 and can supply up to 5 V (1.8 A) of power.
The latest version of USB is 3.1, which was launched in 2013 and doubles the speed of 10 Gbps, making it as fast as the original Thunderbolt standard. It is backward compatible with USB 3.0 and USB 2.0. USB 3.1 has three power profiles and allows larger devices to consume host power: up to 2 A at 5 V (for power consumption up to 10 W) and up to 5 A at 12 V (60 W) or 20 V ( 100 W).
What is a USB Type-B?
USB Type-B connectors, officially called Standard-B connectors, are square in shape, with chamfered outer corners at the upper ends, depending on the USB version.
These type B connectors are supported on all USB versions, including USB 3.0, USB 2.0 and USB 1.1. The second type of connector “B”, called Powered-B, exists only in the USB 3.0 version.
USB 3.0 type B connectors are usually blue, while USB 2.0 type B and USB 1.1 type B connectors are usually black. However, USB Type-B connectors and cables can be any color. A USB type-B male connector is called a plug, while a female connector is called a receptacle or port.
USB type B plugs are typically found on one end of a USB A / B cable. The USB type B plug fits into the printer’s USB type B receptacle or other device, while the USB type A plug fits into the USB type B receptacle. A located on the host device, such as a computer.
Uses of USB Type-B cable
Type B USB cables are more common on larger devices, such as printers and scanners. Sometimes, you will also find USB Type-B ports on external storage devices, such as optical drives, floppy drives, and hard drive enclosures.
Since peripheral devices come in a variety of shapes and sizes, the Type-B connector and its complementary port also come in a variety of designs. Currently, there are five predominant models for USB Type-B plugs and connectors, including the original Standard-B, Mini-B, Micro-B USB, Micro-B USB 3.0 and Standard-B USB 3.0.
The Standard-B design is used to connect large peripheral devices, such as printers or scanners, to a computer and was developed for USB 1.1. The much smaller Mini-B ports are found on older portable devices, such as digital cameras and older portable units, and are becoming obsolete.
Micro-B USB is slightly smaller than Mini and is the most widespread USB port design for smartphones and tablets today. Micro-USB 3.0 is the broadest design and is used mainly for USB 3.0 portable drives; usually, with a Type-A cable end is blue. Similar to Standard-B, Standard-B USB 3.0 is designed to handle 3.0 administration speed.
