    摘要： An optical integrating cavity supplies light or other radiant energy through a port to a deflector. The deflector coupled to the port may form a “fan” extending along one side or around all or part of the circumference of the cavity. Preferred embodiments use principles of constructive occlusion (diffuse reflectivity in a mask and cavity structure) together with the port and deflector structure. The cavity and mask serve as the optical integrating cavity. The constructive occlusion provides a tailored intensity distribution for radiant energy illuminating a first region; whereas the integrating cavity, port and deflector distribute another portion of the electromagnetic energy over a second field of intended illumination. The first and second areas illuminated may overlap slightly, or one may include the other, but preferably most of the two areas are separate. In some cases, the system configuration creates a dead zone between the two regions.

    摘要： A system and method are provided for framing messages in a forward error correction (FEC) structure for data streams encoded with redundant signal conditioning information. The method accepts signal conditioning-encoded words at a first bit rate, and eliminates redundant information in the signal conditioning-encoded words, creating N reduced-bit words of k bits. The k-bit words are mapped into a payload field of N*(k/p) p-bit words. Overhead (OH) and FEC parity fields are generated, and a frame is created including the OH field, payload field, and FEC parity field. The bit values in the frame are then pseudorandomly scrambled and the scrambled frame is transmitted at the first bit rate. A system and method are also presented for recovering the signal conditioning-encoded words from an FEC frame.

    摘要： A system and method are provided for transporting a serial stream via a lower speed network using multiple parallel paths. At a transmitter, an optical or electromagnetic waveform is accepted representing a serial stream of digital information, and unbundled into n virtual information streams. Each virtual information stream is divided into a sequence of segments. Each segment is encapsulated, creating a sequence of packets by adding a start indicator to the beginning of each segment, and a terminate indicator to the end of each segment. Each packet is disinterleaved across m lanes and reinterleaved into n branches of framed data. Optical or electromagnetic waveforms representing the framed data are transmitted via n network branches. A receiver is also provided, which essentially reverses the above-described transmission method.

    摘要： A system and method are provided for negotiating a link data rate in a communication system using a plurality of data rates. In a system including a first device network-connected to a second device, auto-negotiation (AN) messages are mutually transmitted. The AN messages indicate rate information such as preferred data rate capabilities, if the device has a dual-rate capability, single data rate capabilities, or is capable of communicating over a plurality of physical medium lanes. If the AN messages are mutually transmitted, a negotiated link data rate is established. However, if one of the devices cannot send AN messages, the other device times-out, and a link data rate is established at the data rate transmitted by the device that is not AN-capable.

    摘要： A system and method are provided for ordering tap setting modifications in a link partner using a plurality of voltage gain taps, while avoiding minimum and maximum limitations. Provided is a link partner (LP) transmitter having a parallel selectable voltage gain taps. The method sends messages from a network-connected local device (LD) directing the LP to generally change the gain setting of either the pre-tap or the post-tap, as follows. The gain setting of selected tap is changed in the desired direction of modification and then the center tap gain settings is maximally increased until a limit signal is received. If a selected tap increment is desired, the center tap is initially decremented more steps than the desired change in the selected tap.

    摘要： A system and method are provided for framing messages in a data streams encoded with redundant information for transmission and recovering the messages at a receiver. The transmission method accepts an energy waveform representing N words at a first bit rate, encoded with redundant information, where each word includes P number of bits. The N words are transformed, creating N transcoded words, where each transcoded word includes Q number of bits, and where Q 1 and each lane receives a frame of N/M transcoded words. A frame alignment marker is generated and mapped into each frame. Each frame is represented as an energy waveform that is transmitted on a corresponding physical lane at the first bit rate divided by M.
