3-Foot Extension Cable Connects Computers, Printers, Modems and Other USB Equipment
This USB 3.0 SuperSpeed Type-A Extension Cable (M/F) attaches to your current USB 3.0 cable to extend it by three feet. It connects your computer, laptop or other compatible USB 3.0 device, such as a Chromebook or Surface tablet, to a USB-A keyboard, printer, portable hard drive, patch panel or other peripheral. The three-foot length helps reduce cable clutter and minimize the risk of tripping.
Transfers Data at SuperSpeed Transfer Rates up to 5 Gbps
The U324-003-BK supports USB 3.0 speeds up to 5 Gbps—ten times the speed of USB 2.0—and better power efficiency with no device polling and lower active and idle power requirements. The cable’s bi-directional data interface allows data to flow both directions simultaneously, increasing theoretical bandwidth by 10 times. The cable is backward compatible with previous USB generations, allowing you to use it with legacy devices.
