Method and Apparatus for Forming a Lens on an Optical Fiber includes a fiber rotator assembly that receives and axially rotates an optical fiber. In a transmitter unit, a modulation unit modulates a data signal to be transmitted. Link parameters associated with the negotiated data transmission speed are calibrated and implemented in a Phy layer of the interface before data is transmitted across the interface. In a second embodiment, the dedicated logic cell is constructed with a combination of configurable logic functions that are coupled to a dedicated logic function in order to perform a four 2-to-1 multiplexer function. A contact is disposed on the second movable member and functions as a movable contact. When the computing device starts to use more power than the maximum power usage setting, the power used by the computing device is reduced so as not to exceed the setting, such as by decreasing the frequency at which the processor operates.
