    摘要: An automatic optical power management system for use with an optical communications system includes a light source residing in a first circuit pack and adapted to emit light at a nominal power level only absent receipt of an indicator signifying a loss of signal resulting from a fiber discontinuity relating to the first optical fiber, wherein the nominal power level is of sufficient magnitude to violate laser safety guidelines in the event of the fiber discontinuity. A redundant detection system includes a first optical detector residing in the first circuit pack, and a second optical detector residing in a second circuit pack that is optically adjacent to the first circuit. A redundant response system communicates an indicator signifying loss of signal from the first and second optical detectors to the light source upon detection of loss of signal by either detector.

    摘要: Electronic apparatus and method are provided for management of communications between channel master (e.g. audio player), responding device (e.g. remote control/headphones) and, optionally, passive devices (e.g. headphones) wirelessly connected in a wireless audio network. The channel master transmits, and the responding device receives, audio signals and network management information. Profile negotiation means communicates application profiles for the devices, establishing at least one application profile which is common to them and designating a selected, common application profile for use in associating the devices. Channel selection means selects a channel for the communications using an ordered selection of channels (PCS) obtained from scanning the channels for idle channels and ordering the scanned channels according to priority based on channel quality. Normalized control and status interfaces establish interoperability between devices which use different data streams to communicate in the network.

    摘要: A request method for performing optical power management to accomplish planned addition and removal of wavelengths in an optical communications system is disclosed, wherein each wavelength has a path of transmission through the system. The method comprises communicating a request for a power ramp to at least one path network component in the path, determining that the path network component has made preparations for the power ramp, and performing a power ramp in response to the determination. Further, a response method for performing power management to accomplish planned addition and removal of wavelengths in an optical communications system is disclosed, wherein each wavelength has a path of transmission through the system. The method comprises receiving a request for a power ramp, making preparations for the power ramp, determining that the power ramp has been completed, and resuming normal operation in response to the determination.
