What to Consider When Choosing the Best USB Extension Cable
所有USB扩展电缆都有自己的能力。选择USB扩展电缆以同时充电并使用您的设备，请考虑计算机的位置或USB wall outlet所以你选择一个有足够达到的电缆。为避免在计算机中收取充电端口，请考虑一个charging stationorUSB hub为确保您可以在给定时刻使用所需的所有设备。
最好的USB延长电缆需要适用于您的设备的合适长度，耐用，正确的连接器，避免干扰或弱信号，并提供背压保护。在为您的家庭或办公室选择最佳USB扩展电缆时，请继续阅读更多关于这些重要的考虑因素。
Length
当寻找一个USB延长线,长est available item isn’t necessarily the right one for you. The longer the cable, the lower the speed and power that goes to the device. The signal strength between the host and peripheral device is more effective with a shorter distance between them. If you only require a 3-foot extension, you’ll receive more power from a 3-foot cable instead of one that’s 10 feet long.
USB standards indicate that extension cables for USB 2.0 can only reliably transfer data approximately 16 feet. For USB extension cables 3.0 and beyond, there isn’t an actual maximum outlined in USB standards; however, the signal starts to degrade after about 10 feet. If a USB cable doesn’t reach far enough, then you’ll need to invest in a longer cable; it’s not recommended to directly connect one cable to another to acquire a longer distance.
Durability
When purchasing a new USB extension cable, you expect it to last. Bending tests, interior shielding, a cable jacket, and gold plating all increase the durability of a cable and help it to last a long time.
- Many manufacturers performbending testson their cables by repeatedly flexing the cable at the joint to see how it holds up. The higher the bend count, the stronger the cable. Some USB extension cables can withstand over 20,000 bends.
- 这内部屏蔽uses a thin layer of copper or aluminum around the wire to enhance the strength of the cable.
- 一种电缆夹克is the outside of the cable that helps protect the core from mechanical stress and other elements. Thicker PVC jackets or braided nylon jackets may offer more strength and protection of the cable’s core.
- Gold platingon the cable connectors helps resist corrosion because it doesn’t react with oxygen in the atmosphere.
信号强度
Signal strength may be influenced by the length, type, and quality of a cable. USB standards are quite demanding in terms of signal quality, helping ensure that manufacturers are making extension cables that efficiently and clearly transmit signals between the host and peripheral device. Two features that enhance signal strength are a gold-plated finish and repeaters.
- 镀金在USB连接器上提供可靠性和耐用性。黄金是一个优秀的指挥，一些专家认为，此功能可提高信号质量。
- Repeatersin extra-long cables boost signal transmission. They actively fix and strengthen digital data so it can travel farther distances without interference.
数据传输的速度和质量也受电缆的限制。三个最常见的USB扩展电缆是USB 2.0，USB 3.0和USB 3.1。
- USB 2.0正在变得日期，因为它不再内置于新设备。此类电缆上的数据传输速率最多为480 Mbps。
- USB 3.0在许多现代设备上找到。它将数据转移到5 Gbps，超过10倍超过USB 2.0。
- USB 3.1is the upgraded version of USB 3.0 with a transfer rate of 10 Gbps. Both USB 3.1 and 3.0 may have backward compatibility with USB devices made before 3.0 was developed.
Connectors
USB extension cables need to connect to both the host and peripheral devices using USB-A, USB-B, Mini-USB, or USB-C connectors.
USB-A
- 这most commonly used USB connector
- 一种flat, rectangular interface that holds the connection in place by friction
- Used for the upstream connection toward the host device
- USB 2.0,3.0和3.1使用标准类型-A连接器
USB-B
- Not as common as other types of USB cables
- Used on some USB peripheral devices
- Squarish shape with slightly beveled corners on the top ends
- Uses friction to hold the connector in place
- Mostly used to connect external hard drives, printers, and similar devices with computers
Mini-USB
- 具有四边形中心的较小设备的较小连接
- Used for connecting mobile devices, including phones, cameras, and portable game consoles
- Can share data in either direction
USB-C
- Symmetrical design that can be plugged into a USB-C device using either end
- Commonly paired with USB-A and USB-B
- 常用于USB 3.0和3.1的较小端口
- 增强的电源传递和高速数据转移最多10 Gbps
Connectors on each type of USB may be angled rather than flush with the cable. Angled connectors enable users to connect a USB cable in tight spaces. The head may not come straight out of the top of the wire and instead connects at 90 degrees. Connectors may be up, down, right, or left. It fits into a port with the USB symbol facing up.
背压保护
一种s USB cables can be plugged in or unplugged when a host device is on, the current rushes into the cable right away. Overcurrent protection limits the amount of current that the peripheral device can draw from the host device or hub. USB protocol and other standards require overcurrent protection for USB devices.
Back voltage protection prevents damage to power supplies and electronics if the input and output terminals accidentally receive the wrong power supply connection. As the input voltage is higher than the output voltage, it creates an issue if the cable connects the wrong way. Electrostatic discharge (ESD) is implemented into the design of hosts and devices to ensure that they are not adversely influenced by current spikes that occur when devices are plugged in.
