Systems and methods are provided for reducing power consumption of a multi-die device, such as a network processor FPGA (npFPGA). The multi-die device may include hardware resources such as FPGA dies, which may be coupled to NIC dies and/or memory dies. Power consumption of the multi-die device may be reduced by monitoring usage of hardware resources in the multi-die device, identifying hardware resources that are not in use, and gating power to the identified hardware resources. The status of processing elements (PEs) in the multi-die device may be tracked in a PE state table. Based on the PE state table, tasks from a task queue may be assigned to one or more processing elements.

Disclosed are a method and a system for remote wake-up and status check, with a wake-up signal generating unit generating and transmitting a wake-up signal to wake up an electricity supply unit of a remote device to operate normally and provide electricity for the remote device. The wake-up signal has an assigned electric voltage with specific characteristics for detection by the electricity supply unit while in power-off mode and, upon signal detection, the electricity supply unit wakes up to provide normal electric voltage output. The wake-up signal generating unit determines, according to an electric current on a wake-up signal feed line, whether the remote device is in an active mode. A low wake-up energy consumption enables system wake-up and a true powered-off sleep mode.

A telecommunications patching system includes: a carrier having a generally vertically disposed carrier panel, the carrier panel including a cutout area; and a plurality of patching modules. Each of the patching modules has a main panel and a plurality of telecommunications connectors mounted thereon. The patching modules are inserted into the cutout area so that the main panels thereof are substantially parallel to each other, and so that the main panels define an oblique angle relative to vertical. In such a configuration port density can be increased over typical systems.

A method and apparatus for characterizing and compensating optical impairments in an optical transmitter includes operating an optical transmitter comprising a first and second parent MZ, each comprising a plurality of child MZ modulators that are biased at respective initial operating points. An electro-optic RF transfer function is generated for each of the plurality of child MZ modulators.

An IQ power imbalance is determined using the curve fitting parameters. Initial RF drive power levels are determined that compensate for the determined IQ power imbalance. The XY power imbalance is determined for initial RF drive power levels using the curve fitting parameters. The operating RF drive powers are determined that at least partially compensate for the first and second IQ power imbalances and for the XY power imbalance for the optical transmitter.

The array of ports is configured such that there is a gap within each column of ports located between two rows of ports. The gap is wide enough to permit a hitless beam switching trajectory to pass between the two rows of ports from one side of the array of ports to an opposite side.

Methods of automatically tracking a patching connection between a first connector port of a patch panel and a second connector port of a network device are provided in which a sensor is used to detect that a first end of a patch cord has been inserted into the second connector port. The patch cord has at least one data communications channel and a separate control channel. A first conductor of the control channel of the patch cord is biased to power an integrated circuit chip on the network device. In response to the detection by the sensor, a first signal is transmitted over the separate control channel of the patch cord to the network device. A second signal is received over the control channel of the patch cord in response to the first signal. The second signal includes a unique identifier that is associated with the second connector port.

Multiple network switches are configured having memory interfaces that transfer segmented frame data to each other via a data path having multiple rings connecting the network switches. The memory interfaces are also configured for transferring the segmented frame data to respective local buffer memories for temporary storage. The data path transfers the data units between the switches according to a prescribed sequence protocol, optimizing memory bandwidth by requiring only one read and one write operation to and from a local buffer memory for each segmented frame data being received and transmitted through the switches.
