How to Beat the Maximum USB Cable Length Limit
'Most communication protocols used to transfer data between computers and other devices use a signaling method called duplex, including Ethernet and USB. Devices connected in a duplex system can communicate with each other in both directions. So when a USB host sends a “packet” of data to a device connected by a USB cable, it waits for a response before sending the next packet. If no response is received, it tries sending the packet again.
Clearly, timing is very important. As the data transfer rate goes up, the USB host has less time to transmit its data packets and receive a response. The further the signal has to travel, the more likely that an error called a “late collision” will occur, so high data transfer rates typically require a shorter cable'.
4 Ways to Beat USB Cable Length Limitations
Here are four ways to extend USB cable lengths without losing signal strength or quality.- Buy a Passive USB Cable
- Consider an Active USB Cable
- Achieve Longer Distances with USB over Cat5/Cat6 Extenders
- Go the Distance with USB over Fiber Extenders
