What to Consider When Choosing the Best USB Extension Cable
All USB extension cables have their own capabilities. When choosing a USB extension cable to simultaneously charge and use your devices, think about the location of your computer orUSB wall outletso you select a cable with enough reach. To avoid running out of charging ports in your computer, consider a充电站要么USB hubto ensure you can use all the devices you need at a given moment.
The best USB extension cable needs to be a suitable length, durable, the right type of connector for your devices, avoid interference or a weak signal, and offer back voltage protection. Read on to learn more about these important considerations when selecting the best USB extension cable for your home or office.
Length
When searching for a USB extension cable, the longest 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
购买新的USB扩展电缆时，您希望它持续。弯曲试验，内部屏蔽，电缆夹套和金电镀都增加了电缆的耐用性并帮助它持续很长时间。
- 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.
- Theinterior shielding在线使用薄层铜或铝，以提高电缆的强度。
- Acable jacketis 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 plating在电缆连接器上有助于抵抗腐蚀，因为它不会在大气中的氧气反应。
Signal Strength
信号强度可能受到电缆的长度，类型和质量的影响。USB标准在信号质量方面非常苛刻，有助于确保制造商正在制造延长电缆，这些电缆有效，清晰地在主机和外围设备之间发出信号。增强信号强度的两个特征是镀金镀金和中继器。
- Gold-plated finishon USB connectors offers reliability and durability. Gold is an excellent conductor, and some experts argue that this feature improves signal quality.
- Repeatersin extra-long cables boost signal transmission. They actively fix and strengthen digital data so it can travel farther distances without interference.
The speed and quality of the data transfer are also limited by the cable. The three most common USB extension cables are USB 2.0, USB 3.0, and USB 3.1.
- USB 2.0is becoming dated as it’s no longer built into new devices. The data transfer rate on this type of cable is a maximum of 480 Mbps.
- USB 3.0.is found on many modern devices. It transfers data up to 5 Gbps, more than 10 times faster than USB 2.0.
- USB 3.1.is 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
电缆需要连接到USB扩展host and peripheral devices using USB-A, USB-B, Mini-USB, or USB-C connectors.
USB-A.
- 最常用的USB连接器
- A 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, and 3.1 use the standard Type-A connector
USB-B.
- Not as common as other types of USB cables
- Used on some USB peripheral devices
- 正方形形状，顶端有略微斜角的角落
- 使用摩擦将连接器固定到位
- Mostly used to connect external hard drives, printers, and similar devices with computers
迷你USB.
- A smaller connection for smaller devices with a quadrilateral hub
- 用于连接移动设备，包括手机，摄像机和便携式游戏机
- Can share data in either direction
USB-C.
- Symmetrical design that can be plugged into a USB-C device using either end
- 通常与USB-A和USB-B配对
- A smaller port commonly used for USB 3.0 and 3.1
- Enhanced power delivery and high-speed data transfers up to 10 Gbps
每种类型的USB上的连接器可以成角度而不是用电缆齐平。成角度的连接器使用户能够将USB电缆连接在紧密空间中。头部可能不会直接从电线顶部直接，而是以90度连接。连接器可以升级，向下，右侧或留下。它适合与USB符号面临的港口。
Back Voltage Protection
As 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.
