摘要： Disclosed are a system and a method for controlling multicast data. The system may comprise: a plurality of transceivers, each of which comprises a laser configured to generate an optical carrier, the generated optical carrier being modulated by electrical downstream p-t-p data so as to generate optical downstream p-t-p IRZ signal; a PM configured to modulate the generated optical downstream p-t-p IRZ signal by electrical multicast data so as to generate orthogonally modulated signal; and a DI configured to demodulate the orthogonally modulated data and has a frequency response peak or dip in response to the demodulating, wherein an offset of a laser center wavelength of the laser from the frequency response peak or dip is adjustable so as to selectively enable or disable the multicast data.

摘要： Systems and methods which utilize antenna pattern or antenna beam scanning techniques to provide communication of payload traffic are shown. A base station radio is provided wireless communication links with a plurality of stations for communication of payload traffic between the base station and stations using a succession of antenna patterns. The antenna patterns are scanned in succession, such as randomly, quasi-randomly, sequentially, or according to a schedule. An antenna pattern scheduler may be used to implement antenna pattern scanning and traffic timing. Cooperative scheduling with respect to a plurality of base stations may be provided. Selection of the plurality of antenna patterns used by a base station is preferably adjusted from time to time, such as based upon environment, usage patterns, etcetera.

摘要： A surveillance system for in-service fault identification in an amplified passive branched optical network is provided. This system does not require any wavelength tunable light source as used in multi-wavelength OTDR. Fiber-Bragg gratings are placed at some strategic positions on different fiber branches to slice and reflect the optical amplifier's residual ASE power at some wavelength other than the signal wavelengths. The conditions of the fiber link and optical amplifier at each branch can be monitored by constantly checking the reflected power level of the corresponding wavelength without suspending the in-service channels.
