Each of the plugs of the AOC has an optical-to-electrical and an electrical-to-optical (OE/EO) conversion module that converts electrical USB signals output from the USB host or USB device into optical signals and converts optical signals carried on the optical fibers of the AOC into electrical USB signals. The plugs include controllers that monitor certain conditions of the AOC and that select the power levels to be used in the plugs based on detected conditions.Type: GrantFiled: July 30, 2013Date of Patent: November 4, 2014Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventor: Frederick W. Miller
