摘要： A system for overlaying an analog broadcast channel in a Wavelength Division Multiplexed Passive Optical Network (WDM-PON). A remote node of the WDM PON includes a MUX/DEMUX for demultiplexing a Wavelength Division Multiplexed (WDM) signal and supplying respective wavelength channels to each one of a plurality of channel fibers; an optical power splitter for supplying the analog broadcast channel to each one of a plurality of distribution paths; and a respective optocoupler connected to each distribution path, each opticoupler coupling the analog broadcast channel into one of the channel fibers. The analog broadcast channel has a wavelength that is outside a wavelength band of the WDM signal. An Optical Network Terminal (ONT), which is connected to one of the channel fibers, includes a triplexer for separating the analog broadcast channel from at least a downlink wavelength channel of the WDM-PON.

摘要： A control system is designed to control an optical cross-connect having a switch core defined by first and second independently movable beam deflectors capable of selectively defining an optical path between a pair of ports of the optical cross-connect. An optical element having optical power is arranged in a propagation path of light beams between the first and second beam deflectors. The control system includes a pilot light source, an optical sensor associated with each beam deflector, and a feedback path. The a pilot light source inserts a pilot light into the switch core colinearly with live traffic. The optical sensor detects a predetermined geometric property of the pilot light emerging from the switch core. This predetermined geometric property is unambiguously associated with an angular position of the associated beam deflector. The feedback path actively controls a position of the associated beam deflector based on the detected geometric property.

摘要： The invention relates to optical communications using techniques for providing efficient high speed polarization bit interleaving. One common architecture for high-speed time-division-multiplexing employs two modulators having a same bit rate, wherein two separately modulated streams of data bits are combined into a high-speed single serial stream of data bits, instead of providing a single higher-cost higher-speed modulator. The present invention has found with the availability of fast data modulators, that polarization bit interleaving can be employed more efficiently for higher speed data transmission in optical network systems by providing an optical modulator including a single data modulator, rather than multiplexing different data streams from different modulators. The present invention provides an optical modulator for encoding data on orthogonally polarized alternate light pulses comprising: means for modifying a laser light beam to a pulse train at a first frequency; a data modulator for encoding signal data on the pulse train at a second data stream frequency where the second frequency is greater than or equal to the first frequency; means for rotating a polarization state of at least alternate light pulses of the pulse train to provide a data stream of orthogonally polarized alternate light pulses.

摘要： In a method of compensating polarization dependent loss (PDL) in a wave division multiplex (WDM) optical communications system, a performance parameter is monitored at a predetermined monitoring point. The performance parameter is indicative of respective channel PDL for each one of a plurality of channels of the optical communications system. A error function is calculated as a function of wavelength across a wavelength spectrum of interest, using the measured performance parameter values. Finally, a broadband PDL compensator is controlled based on the calculated error function.
