摘要： A media converter has an electrical bus port for connecting a first electrical bus; and an optical bus port for connecting an optical bus. The media converter is configured to convert an electrical signal of the first electrical bus into an optical signal of the optical bus in such a way that, at a first value of an internal control signal of the media converter, the optical signal corresponds to the electrical signal and, at a second value of the internal control signal, the optical signal has an inverted shape corresponding to the electrical signal. In a transmission phase during which the internal control signal changes from the first value to the second value, the media converter is configured to emit the optical signal in such a way that the optical signal corresponds to the electrical signal until the end of the transmission phase.

摘要： An optically-switch data network includes an optical data bus, an optical wavelength bus, and multiple nodes connected by the optical data bus and the optical wavelength bus. A first node determines that it has communication information to transmit to a second node, and determines if a first subscription signal is present on the optical wavelength bus. The first subscription signal includes a target frequency. If the first subscription signal is not present on the optical wavelength bus, the first node injects an optical communication signal onto the optical data bus. The optical communication signal includes the communication information and a carrier wave. The carrier wave includes the target frequency. The second node receives the optical communication signal using the optical data bus. If the first subscription signal is present on the optical wavelength bus, injection of the optical communication signal onto the optical data bus is postponed.

摘要： An optical bus system (1) having a start-up state and at least one operating state is disclosed. The optical bus system (1) includes a mechanical support structure (21) arranged to receive and hold a master module (2) having a downstream optical interface (3) and a set of slave modules (6) each having an upstream optical interface (7) and a downstream optical interface (8). The modules are attached to the mechanical support structure (21) such that optical interfaces of adjacent modules are aligned and in close proximity to each other in order to enable optical communication (24, 25) between adjacent modules. Each slave module (6) is further provided with circuitry to form one or two shunting signal paths (30, 31) depending on operating state after an addressing procedure is completed in the start-up state. Hereby, it is e.g. possible to realize a robust and cost-efficient optical bus system with high bandwidth capability.

摘要： A telecommunication system employs dynamic shaping across a plurality of access modules of an access node using a dynamic bandwidth allocation (DBA) algorithm that is based on current load conditions for each of the access modules in order to achieve a fair allocation of network bandwidth at the access node. In one exemplary embodiment, access modules at an access node communicate via a control channel with shaper control logic that receives load information from each of the access modules. Using such load information, the shaper control logic dynamically controls the shaper rates for the access modules so that a fair allocation of network bandwidth is achieved across all of the access modules. Specifically, the shaper rates are controlled such that packet flows for services of the same class achieve the same or similar performance (e.g., average data rate) regardless of which access module is communicating each respective packet flow.

摘要： A bus-based optical network system comprising optical fibers, optical line terminals (OLTs), and a plurality of optical network units (ONUs) is revealed. The OLT consists of the near part (OLTN) and the far part (OLTF). Optical fibers respectively form the transmitting and receiver buses (T Bus and R Bus) with the technique of time-division multiple access (TDMA). The slot flows on both buses are in opposite directions. The OLTN performing traffic control is situated in or near a central office (CO) while the OLTF is far from the CO. ONUs, whose MAC performs traffic control, connect with two buses and share their bandwidth. The MAC with traffic control keeps the performance of the network from degradation. The required numbers of COs and optical fibers for establishing the bus-based network are so smaller that the cost of the network can be significantly reduced.

摘要： Messages on controller area net work (CAN) buses are communicated over subsea optical links. An adaptor couples a CAN bus to an optical link. The adaptor detects a direction of transmission, that is, whether a signal began on the CAN bus coupled to the adaptor or on the optical link coupled to the adaptor. Signals from the CAN bus are conditionally transmitted to the optical link depending on the detected direction of transmission. The adaptor can operate at the physical layer without analyzing contents of the CAN bus communications.
