    摘要: A baseband burst mode optical transmitter for receiving reverse electrical signals and for providing a reverse optical signal. The baseband burst mode optical transmitter includes an analog-to-digital converter and a framer/encoder circuit for adding a synchronization word and a start-of-data word to the reverse digital signals. Additionally, a carrier detect circuit is included for detecting the presence of a carrier signal included in the reverse electrical signals, whereby when the carrier detect circuit detects the presence of the carrier signal, the optical transmitter transmits optical signals (i.e., optical signals are only transmitted if the reverse electrical signals include the carrier signal). A baseband burst mode optical receiver receives the optical signals and strips the synchronization word and start-of-data word from the digital signals and then converts the signals back to analog signals.

    摘要: An optical network may be configured dynamically so that a given channel wavelength can operate in either direction over a fiber in a network. Thus, network providers can provision bandwidth according to the traffic characteristics of the network link in question. A plurality of transceiver modules on either side of a fiber may be switched from a transmit mode to a receive mode depending on the desired direction of the channel.

    摘要: An open-path/free-space optical communication system using reflected light has modulated optical or laser sources and provides communication between the modulated source and a detector in an obstructed line-of-sight relationship. The system detects backscattered light impinging on a target illuminated by the source of light. Barrier objects positioned in a line-of-sight path between the source and detector are circumvented and a first device that provides the modulation signal for the source controls a remote second device.

    摘要: An architecture and method for performing coarse-grain reservation of lightpaths within wavelength-division-multiplexed (WDM) based photonic burst switched (PBS) networks with variable time slot provisioning. The method employs a generalized multi-protocol label switched (GMPLS)-based PBS label that includes information identifying each lightpath segment in a selected lightpath route. A resource reservation request is passed between nodes during a forward traversal of the route, wherein each node is queried to determine whether it has transmission resources (i.e., a route lightpath segment) available during a future timeframe. Soft reservations are made for each lightpath segment that is available using information contained in a corresponding label. If all lightpath segments for a selected route are available, the soft reservations turn into hard reservations. The stored reservations enable quick routing of control burst that are employed for routing data during scheduled use of the lightpaths.

    摘要: The present invention involves a method and system for transmitting data in an optical or hybrid optical and RF wireless network from a base structure including a base apparatus to a target device including a target apparatus. The base apparatus includes a base receiver, a laser, a device for positioning the laser-emitted beam, and a base microprocessor. The target apparatus includes a target transmitter, a photodetector, and a target microprocessor. Once the target device comes to a rest beneath the base structure, the target transmitter communicates the presence of the target apparatus to the base receiver. A communication uplink is established between the target apparatus and the base apparatus. The base microprocessor then activates the laser and instructs a commercial laser based steering system to continually adjust the position of the laser beam in a search pattern until it illuminates the photodetector, at which time a communication downlink is established between the base apparatus and target apparatus. Data is then transmitted from the laser to the photodetector via the communication downlink at speeds of 100 Mbps to 10 Gbps.

    摘要: The system and method of the present invention optically transmits redundant packets of data using infrared signals at pseudo-random intervals to allow a receiver to distinguish between multiple simultaneous sources. The emitters repeatedly transmit a short packet at randomized intervals much shorter than the frame rate. Statistical analysis shows that the probability of collision of the desired packet with a packet from some other source is sufficiently low such that timely reception of at least one uncorrupted packet in the required time frame is assured.

    摘要: A technique for optical fiber management in a chassis-based network system involves using a blind mating optical interface at the back of a line card and an optical transceiver interface that is accessible from the front of the line card. The blind mating optical interface and the transceiver interface are optically connected by an optical signal path that includes and optical fiber. When the line card is secured within a compatible chassis, the blind mating optical interface of the line card connects to a blind mating optical interface of the chassis and creates an optical connection between an external optical fiber and the transceiver interface.
