摘要： Method and system for reducing power dissipation for data transmission from a transmitter to a receiver in a digital subscriber line (DSL) system when a rate of available data is below a first predetermined data rate for a predetermined length of time. The method includes the following steps. Normal parameters for a normal rate of said data transmission are stored. New parameters for a reduced rate of the data transmission are calculated. Data is transmitted at the reduced rate of the data transmission, wherein the reduced rate requires less power for data transmission. The normal rate of the data transmission is resumed using the normal parameters when the rate of available data rises above a second predetermined data rate.

摘要： Consistent with the present invention, tunable demultiplexers are provided in WSS-based add/drop multiplexer. The tunable demultiplexers are modular and thus allow the add/drop multiplexer to be readily expandable, and facilitate flexible add/drop capabilities whereby a channel present on any input line to the WSS can be dropped and supplied to one or more desired outputs of the tunable demultiplexer. Similar flexibility can be achieved on the add-side of the WSS. Moreover, the demultiplexers and the WSS are remotely configurable, thus obviating the need to manually disconnect and connect demultiplexers to a router. In a particular embodiment, multicast switches are provided that permit the same channel, for example, to be provided to one or more outputs of the add/drop multiplexer, such that copy of the channel can carry working traffic while the other copy carries protection traffic. As a result, 1+1 and 1:N optical layer protection can be achieved.

摘要： An arrangement that allows transmission of client signals with higher clock fidelity is achieved by developing a phase offset measure at an ingress node, communicating it to the egress node, and recovering the client's clock from the received data and from the received phase-offset information. The ability to recover the client's clock with high fidelity is enhanced by adaptive pointer processing in intermediate nodes and the egress node of the network that the client's signal traverses. The adaptive pointer processing filters incoming pointers from upstream nodes and injects new positive and negative pointer justifications in excess of what is minimally necessary to allow them to be filtered by successive nodes and insure proper transmission over a network that employs a protocol involving framing layer frames embedded in communication layer frames. Illustratively, the network protocol is an extended ITU Recommendation G.709 Digital Wrapper protocol, arranged to employ frames of 15240 columns by four rows.

摘要： A method, system and egress switching node for maintaining a network connection in an optical network reduces the number of spans needed for reestablishing a network connection. The invention learns which channels are used by the network connection and propagates such channel assignment data to the switching nodes for storage therein. When a span failure occurs, a notification is sent to the switching nodes identifying which span has failed. The switch nodes use the notification and channel assignment data to perform protection switching such that the rerouted network connection selects the channel that was used by the network connection on the failed span. Likewise, the egress switching node uses the selected channel to drop the network connection from the protecting fibers. This enables a network connection to travel a shorter distance after a protection switch.

摘要： An optical selector device is disclosed that includes a first arrayed waveguide grating (AWG) demultiplexing an input WDM signal and outputting demultiplexed signals on respective outputs; an array of optical shutters optically coupled to the outputs from the first AWG; a second AWG optically coupled to the array of optical shutters, the second AWG multiplexing optical signals output from the array to form a WDM signal; and a common optical shutter optically coupled to either of the first and second AWGs. The common optical shutter has a default state that is substantially opaque to the WDM signal. Additionally, the array of optical shutters may have a default state that is substantially transparent to the demultiplexed signals. A reconfigurable wavelength blocking device incorporating the optical selector device is also disclosed which additionally includes a controller that controls the optical shutter array to selectively block/pass designated wavelength channels or bands.

摘要： Optical amplifying method and apparatus are proposed. Constant gain amplifiers operate such that the output power of the amplifier generally tracks the input power. However, optical systems are not perfect and the input to the optical amplifier stage includes not only the desired signal, but also includes accumulated effects of the imperfections. The imperfections include losses of the fiber sections, variations in laser powers, and drifts. Thus, simple amplification not only amplifies the desired signal, but also amplifies accumulated imperfections. Such imperfections occur over time and are generally small in magnitude. By operating the amplifier such that amplification of small variations is suppressed while allowing for tracking of large input variations, amplifying the accumulated imperfections is minimized.
