A function-specific network interface module is provided which includes a housing and a connection interface at opposing ends of the housing configured to connect to another function-specific network interface module in a cascaded manner. The function-specific network interface module further includes one or more circuit components operable to provide a dedicated network function so that a plurality of different network functions is provided when the function-specific network interface module is connected to the other function-specific network interface module via the connection interface.

A crossbar may be coupled between a plurality of PHY devices configured to provide physical layer functions according to an Open Systems Interconnection, OSI, model and a plurality of MAC devices configured to provide data link layer functions according to the OSI model. First data couplings may be provided through the crossbar between the plurality of PHY devices and the plurality of MAC devices during a first time period. Second data couplings may be provided through the crossbar between the plurality of PHY devices and the plurality of MAC devices during a second time period, with the first and second data couplings being different. Related network elements, interfaces, and networks are also discussed.

Exemplary embodiments provide for methods and systems that enable frame generation by fields taken from various queues. Protocol control can also or alternatively be distributed so that one or more header fields can be generated separately from other portions of a frame, e.g., the payload. The one or more header fields can be entered into queues from which they are taken to generate frames.

An optical patch unit is adapted for mounting in or on an optical equipment rack and facilitates a migration from one optical shuffle box or topology to another. The optical patch unit simplifies the replacement of an optical shuffle box, in some cases allowing a phased migration that minimizes system down-time. The optical patch units described herein include passive optical patch panels. Chassis card and optical shuffle connections are terminated at the passive optical patch panel, making it possible to simplify the cabling between the chassis cards and the optical shuffle box. Once installed, chassis card cables do not need to be manipulated at all during subsequent optical shuffle maintenance procedures. Other optical patch units described herein include active optical patch units, which make the migration process less dependent on human intervention and can further reduce system down-time.

The invention relates to a method and circuit for aligning a serial bit stream with a parallel output. The method comprises latching Q bits from the serial bit stream into a register, locating a position P of a first bit of a start of frame delimiter (SFD) in the register and discarding P-1 bits from the serial bit stream, before the position of the first bit of the SFD, thereby aligning the serial bit stream with the parallel output. The circuit comprises a latch, a fault tolerant analysis logic (FTAL) for locating a position P of a first bit of a start of frame delimiter (SFD) in the register and a shift register for discarding P-1 bits from the serial bit stream, before the position of the first bit of the SFD, thereby aligning the serial bit stream with the parallel output.

An optical physical interface module is provided which includes a first optical physical interface, a second optical physical interface and one or more optical components. The first optical physical interface is configured to plug into a first connector and communicate optical signals toward the first connector. The second optical physical interface is configured to receive a second connector and communicate optical signals toward the second connector. The one or more optical components are operable to process optical signals between the first and second optical physical interfaces. The optical physical interface module may be provided at the edge of a circuit board so that the circuit board has an optical interface for external communication. The optical physical interface module may be a stand-alone module or integrated into a connector of an optical cable, among other configurations.

摘要:
Fluid-cooling technology developed for printed circuit boards (PCBs) and electronics assemblies is combined with optical-based interconnect technology, thereby enabling efficient fabrication of PCBs with free-space optical bearers. Since cooling components such as fans and heat sinks are no longer required on the PCB, the PCB is thinner and makes better use of a cooling substrate by also using it to carry optical signals. A card or a backplane supporting a plurality of active components can combine optical signals and cooling aspects in support of those components.
