Abstract: Embodiments of the invention are directed to an optical USB (OUSB) to enhance the data rate of USB by adding super-high data rate (e.g. 10 Gbps) optical communication on top of its current specification so that backward compatibility is achievable. Mechanical tolerances may be achieved by using embedded lenses to expand a beam emerging from the connector prior to entering its mating connector and using an identical lens in the mating connector to collimate the beam back onto a fiber.

Abstract: Described is a method and apparatus for generating a mid-level reference signal and for cancelling amplifier offset in an optical communication system without DC-balancing of optical data. The apparatus comprises an optical-to-electrical converter to receive an optical signal and to generate an electrical signal; an amplifier to receive the electrical signal and to generate an output signal based on a reference signal; a feedback mechanism to be enabled during a training phase only and to generate a control signal from the output signal; and a counter logic having a digital-to-analog converter to generate the reference signal based on the control signal.

Abstract: A connection port provides electrical and/or optical interface capability. The combined electrical and optical interface port may include an optical communication light engine within the connection port itself. The connection port includes a connector housing, an electrical interface assembly, and an optical interface assembly incorporated together. One implementation of the optical communication light engine includes a laser diode to generate optical signals, a photo diode to receive optical signals, and an optical integrated circuit (IC) to control optical interface.

Abstract: Described herein is an apparatus for improving bandwidth of a transceiver system e.g., a Universal Serial Bus (USB) micro-B connector. The apparatus comprises a first pair of lens units, each lens unit of the pair positioned on either side of an input-output (I/O) bus interface, the pair of lens units to send and receive optical signals respectively; a first housing to shield the first pair of lens units and for physically coupling the I/O bus interface and the first pair of lens units to a receptacle; and a key to grasp the first housing and to lock the first housing with the receptacle.

Accordingly, a floating barrel blind mate optical connector is described which floats with many degrees of freedom for easy connections and accommodates expanded beam connectors to alleviate many common drawbacks.

Abstract: A driver circuit is coupled to an optical waveguide transmitter. The driver circuit has a current generator that is in series with the transmitter, and a current robbing circuit is coupled to the transmitter. The current robbing circuit is to divert first and second amounts of current from the transmitter, in accordance with predetermined values of first and second bit streams, respectively, in which data is received to be transmitted. Other embodiments are also described and claimed.

Abstract: Described herein are connector alignment techniques and components that use alignment bumps and notches to facilitate high-bandwidth scaling. The alignment bumps may be located, for example, on the Converged I/O (CIO) standard-A receptacle and plug housings, on a USB compliant receptacle/plug pair, on a HDMI interface. That is, the alignment techniques and components described here in may be used with virtually any optical interface. The features may be molded into the receptacle housing to become one piece.
