摘要： A device for directing one or more optical channels includes one or more micromirror elements. A micromirror element has a mirror and a mirror controller. The mirror is operable to reflect light at a first interaction area to yield a first passband for an optical channel, and to reflect light at a second interaction area to yield a second passband for the optical channel. The mirror controller operates to position the mirror at a first position at which light interacts with the first interaction area to yield the first passband, and to position the mirror at a second position at which light interacts with the second interaction area to yield the second passband.

摘要： An optical network is provided that carries optical traffic in multiplexed wavelengths between a number of nodes. The network includes at least one light-trail associated with one of the wavelengths and established between a subset of the nodes in the network. The network also includes an out-of-band control channel that is associated with a different wavelength than the light-trail. The control channel is used to communicate control messages to establish the light-trail and to allocate use of the light-trail by the subset of nodes. Each of the subset of nodes comprises a burstponder operable to receive data traffic from one or more client devices of the associated node to be communicated over the light-trail and to buffer the received data traffic and assemble the data traffic into an optical payload. The burstponder is also operable to transmit the optical payload over the light-trail as optical traffic using a burst mode transmitter during a time period in which the associated node is allocated use of the light-trail.

摘要： An optical network is operable to carry optical traffic in a plurality of wavelengths between a plurality of nodes. The optical network includes a light-trail, a convener node, one or more intervening nodes, and an end node. The light-trail is established in the optical network between the convener node and the end node and couples the convener node, the intervening nodes, and the end node. Furthermore, the light-trail is associated with one of a plurality of wavelengths. The convener node and the intervening nodes are each operable to determine whether another node having a higher priority is transmitting optical traffic on the light-trail and, in response to determining that no node having a higher priority is transmitting on the light-trail, transmit optical traffic to one of the nodes in the light-trail. The convener node and the intervening nodes are each further operable to indicate to one or more nodes on the light-trail that optical traffic is being transmitted on the light-trail.

摘要： A method for providing a storage area network includes receiving, at a data storage node, data from a number of storage area network (SAN) servers via associated local nodes coupled to a optical network. The data is received at a plurality of transmitting wavelengths, where each local node is assigned a different transmitting wavelength. The method also includes storing the received data at the data storage node and sending acknowledgement messages to SAN servers to indicate receipt of the data. The acknowledgement messages are sent via the local nodes at a single receiving wavelength and each local node is configured to receive this receiving wavelength. The method may also include receiving, at the data storage node, a request for data stored at the data storage node from any of SAN servers via the associated local node at the assigned transmitting wavelength of the associated local node. Furthermore, the method may include sending the requested data from the data storage node to the requesting SAN sever via the associated local node at the receiving wavelength.

摘要： An optical access network includes a first ring and a second ring communicating optical signals in opposite directions. The network also includes an access node coupled to both rings that adds traffic in a first wavelength of a first optical signal communicated on the first ring. Furthermore, the network includes a hub node coupled to each ring and coupled to an optical core network. The hub node receives the first optical signal, forwards a first copy of the signal to a first wavelength blocking unit that terminates the traffic in the first wavelength, and forwards a second copy of the signal to a first network interconnection element that forwards the traffic in the first wavelength to the core network. Furthermore, upon detection of an interruption of the traffic in the first wavelength on the first ring, the access node adds the traffic in a second wavelength of a second optical signal communicated on the second ring. In addition, the hub node receives the second optical signal, forwards a first copy of the signal to a second wavelength blocking unit that terminates the traffic in the second wavelength, and forwards a second copy of the signal to a second network interconnection element that forwards the traffic in the second wavelength to the core network.

摘要： An optical network includes an optical ring, a plurality of local nodes, and a data center node. The plurality of local nodes are coupled to the optical ring and each local node is capable of receiving traffic from a local client and associating a transmitter tag with the traffic. The transmitter tag identifies a virtual network of the local client. The local node is further capable of transmitting the traffic on the optical ring. The data center node is also coupled to the optical ring and is capable of receiving traffic transmitted by one of the local nodes and determining a receiver tag for the traffic, based on the transmitter tag associated with the traffic and the local node that transmitted the traffic. The data center node is also capable of associating the selected receiver tag with the traffic and transmitting the traffic on the optical ring.

摘要： A method and system for controlling the gain of the amplification of an optical signal is provided that includes both electrical feedforward and feedback. In a feedforward portion of an optical amplifier, the method includes receiving an optical signal and measuring an input power. Based on the measured input power and a desired gain, a feedforward pump power is determined. The pump power is adjusted based on the determined pump power. In a feedback portion of an optical amplifier, an output power is measured and gain is determined based on the output power and the measured input power. The measured gain is compared to a desired gain and the pump power is adjusted based on that comparison.
