Due to some needs, we have to buy a USB extension cable to increase the transmission distance of the USB port. The USB extension cable is mainly composed of two parts: one network cable and two USB interfaces. The interface is connected to both ends of the network cable, so the USB male or USB female can be combined as needed.
The USB extension cable has 128 shield layers. It can achieve better shielding and transmission function. It has a USB disposal chip and connects all USB devices through the extended specification USB port. The farthest interval can reach 5 meters. The USB cable can be used to pass the standard USB interface on two hosts. Transfer data between.
Advantages of the usb extension cord:
1 . Protection socket: The external electronic device does not need to be plugged and unplugged directly on the host computer, which not only protects the interface of the USB device, but also facilitates the use.
2. USB extension cable is mainly composed of two parts: one network cable and two USB interfaces. The interface is connected to both ends of the network cable, and may be any combination of a USB male or a USB female if necessary. USB extension cable with 128 braided shield. It can achieve better shielding and transmission effect. It has a USB processing chip and connects all USB devices by extending the standard USB port. The maximum distance can reach 5 meters. USB cable can be used to connect two hosts through the standard USB interface. Transfer data between.
Disadvantages of usb extension cord:
So, will the USB extension cable cause the signal to decay and cause the transmission speed to drop? The answer is yes, whether it is USB2.0 or USB3.0 extension cable will have an impact.
the speed decay of usb3.0 is inevitable;
Unlike the previous USB 2.0 standard, the USB 3.0 standard has higher requirements on the quality and length of the cable. Speed attenuation is almost inevitable when using the USB 3.0 extension cable. It is also because of this, the length of the USB3.0 extension cable is definitely as short as possible. The USB3.0 extension cable on the market generally only has four specifications of 0.6 meters, 1 meter, 1.5 meters and 2 meters. Consumers can purchase according to their own needs. The well-known STC in the industry does not even have a specification of 2 meters. The purpose is to effectively avoid speed decay. What we have to do is actually to choose the best, and choose the products with the least speed attenuation among the many USB3.0 extension cables.
So how long is the usb extension line?
Due to the uneven quality of the usb extension cord on the market, it is generally recommended that the extension of the extension line within 1 meter will not be too slow. If you want to buy an extension cord of more than 3 meters, you must choose a good one. Divided into goods.
I use a 5 meter USB3 extension cable with a chip that I can barely use.
If you don't have a chip, it seems very unstable. I still have a 5 meter chip without a chip, which is almost unusable.
I bought a 10m USB2.O cable before, and I have a very good impression. It is very fast. When the length of the USB cable reaches a certain level, the material and wire of the connector are very particular.
