The USB Active Extension Cable from Belkin ensures you get the best performance & maximum data integrity when you transfer information between your computer & devices. It uses active electronics to sustain your data signal, so you can connect a peripheral to your PC from an extra 16 feet away. Standard (passive) USB extension cable connections can cause significant data loss over distances of more than 16 feet. With the Belkin USB Active Extension Cable, you can connect up to four of these cables in a series along with a device cable for a total operating distance of up to 80 feet.
