It's an Ethernet cable. It does its job, I've seen speeds of 100mbps without a problem, and it's a very durable cable. It's lasted several years with no problems in connection. The only negative thing I could say about it is that it is somewhat difficult to take the cable out sometimes, given the clip and plastic covers on the side . This is mostly a problem if your device is pushed against the wall, its hard to clip the ethernet cable out. beside that, it does the job well
