  • Patent number: 10447420
    Abstract: Embodiments include methods and apparatuses for providing at least one signaling indication of a super-channel by a power controller in a Wavelength Division Multiplexing (WDM) system. The power controller may receive a service provisioning and a lock state from a network management entity. The power controller may receive, from an optical fabric unit, a fabric state that indicates whether a pass-band of the super-channel is provisioned. The power controller may receive the power level of the super-channel from a power monitoring unit. Based on the power level and attenuation level of the super-channel, the power controller may determine a ramp state that indicates whether the power level reached to a predetermined power. The power controller may determine an alarm state based on the power level. The power controller may determine the signaling indication based on the service provisioning, lock, fabric, ramp, and alarm states.

  • Patent number: 10389469
    Abstract: Systems, methods, and devices for adding an alien or native wavelength optical signal to a fiber optic line. A portion of a spectrum of the fiber optic line corresponding to the optical signal is blocked with a wavelength selective switch (WSS). The portion of the spectrum is gradually unblocked until a power of the optical signal measured after the WSS is equal to a predetermined level. If the power and characteristics of the optical signal after the WSS satisfy one or more criteria, the portion of the spectrum is further unblocked until the power of the optical signal measured at the output is equal to an operational level.

  • Patent number: 10382567
    Abstract: A method of many-to-one auto-discovery between modules includes: a source (sender) module sends the same source-ID on all its connected ports (many). The module may not know on which port the ID is sent. A sink (receiver) module is capable of receiving IDs on its port (one). The sink port identifies the association-ID (AID) of one end of the association (between sender and receiver). The association may be established based on each module discovering the sink AID of the sender in both directions (bi-directional). Both directions may be required for the source signal to get received on a respective sink. The source signal may be sent asynchronously in each direction.

  • Patent number: 9973294
    Abstract: A node in an optical network may include a wavelength selective switch (WSS) and a processor. The wavelength selective switch may have a plurality of input ports and a plurality of output ports for routing and/or power-controlling of optical slices. The wavelength selective switch may have a plurality of control passbands, each control passband including a one or more optical slices. The processor may determine a passband group (PBG) having a plurality of PBG passbands, each of the plurality of PBG passbands corresponding to a particular control passband. The PBG may be used to translate control information, notifications, and/or instructions.

  • Patent number: 5677890
    Abstract: A method and apparatus providing a battery backup for a dynamic random access memory (DRAM) cache system that senses the V.sub.cc level supplied through the cache controller to the cache memory and, if V.sub.cc falls below a preset threshold level, the battery backup apparatus switches the cache memory array to a backup battery V.sub.cc source, and a backup refresh control generator unit that is also powered by the backup battery V.sub.cc source. The cache DRAM, backup battery, and backup refresh generator are physically contained in a single module that can be disconnected from the cache controller and host computer system while preserving the cache memory contents. The backup system is installed in an operating host system for recovery of the cache memory contents and/or resumption of execution of the program that was running when the V.sub.cc power failure occurred.
