US Classification:

398 47, 398 45, 398 48, 398 50, 398 51, 398 54, 370351, 370352, 370355, 370389

Abstract:

Systems and methods for optical cross connects which switch data at a container (packet) level. In one embodiment, a plurality of optical switch edges are coupled to an optical switch core via a minimal number of optical fibers. The switch core is configured to optically switch data from an ingress edge to one of a plurality of egress edges in a nonblocking fashion. The ingress edge receives data streams and distributes the data among a plurality of container processors. Each of these container processors produces an optical signal of a different wavelength, which can then be multiplexed with others to form a multiple-wavelength optical signal that is transmitted to the switch core. The switch core then switches successive portions (containers) of the multiple-wavelength signal to the egress edges to which they are respectively destined. The respective egress edges perform the reverse of this process to form output data signals.

US Classification:

Abstract:

Embodiments of the present invention provide a system and method for routing optical data. In one embodiment of the present invention, data can routed in a non-blocking fashion from a plurality of the ingress edge units to a plurality of egress edge units by selectively connecting the ingress edge units to the egress edge units at a photonic core. Switching at the photonic core can be driven by a clock signal and does not require an electrical to optical conversion to occur at the core. This can allow switching on the nanosecond level, substantially faster than many prior art systems.

International Classification:

H03D 3/24

US Classification:

375376, 375316, 375215, 370503, 327331, 327147, 327156, 329325, 342103, 4551651, 455260

Abstract:

Systems and methods for aligning the phase of a PLL with an incoming data signal. In one embodiment, when a data signal is received in a PLL, a phase perturbation signal is generated and injected into the PLL. The PLL then performs a phase alignment procedure to lock on to the received data signal. The phase perturbation signal is a damped sinusoidal oscillation that is injected into the PLL when each of a plurality of data packets is received. The perturbation signal has an amplitude sufficient to bump the PLL out of a quasi-stable state around 180 degrees out of phase with the incoming data signal, but is damped to less than a degree of phase shift within 30 ns of being injected.

Abstract:

Systems and methods for determining a slicing level which is used as a threshold to determine whether timeslots of an incoming data signal contain ones or zeros. The method of one embodiment comprises receiving a data signal, identifying a maximum level of the data signal, identifying a minimum level of the data signal, determining an average of the minimum and maximum levels, and then using the average of the minimum and maximum levels as a slicing level to identify bits of a data packet embodied in the data signal.

International Classification:

H04W 16/20
H04W 48/16
H04L 12/10

Abstract:

Techniques for identifying one or more wireless access points (APs), from among a plurality of APs including 6 GHz radios, as candidates to operate in standard power indoor (SPI) mode. Identification is based on at least one of: determining that network switches associated with the wireless APs meet a threshold requirement relating to power over ethernet (PoE) for operating in SPI mode, determining, based on at least one of radio frequency (RF) density and channel quality relating to the plurality of APs, that the one or more APs should operate in SPI mode as opposed to lower power indoor (LPI) mode, and determining that operating the one or more APs in SPI mode improves quality of service (QoS) metrics for the plurality of APs as opposed to operating the one or more APs in LPI mode. The one or more wireless APs are configured to operate in SPI mode.
