摘要： An optical network includes an optical ring that is capable of transmitting, between two or more nodes, a plurality of working traffic streams that include traffic transmitted in one of a plurality of wavelengths. A node is capable of transmitting, in a first wavelength, a first protection traffic stream associated with a first working traffic stream, in response to an interruption of the first working traffic stream. A node is also capable of transmitting, in a second wavelength, a second protection traffic stream associated with a second working traffic stream, in response to an interruption of the second working traffic stream. The optical network also includes a regeneration element capable of selectively regenerating the first protection traffic stream. The regeneration element is also capable of tuning the regeneration element to receive traffic in the second wavelength and of selectively regenerating the second protection traffic stream.

摘要： An optical network is disclosed 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 convener node and an end node, and including one or more intervening nodes. 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 convener node and the intervening nodes. Each of the convener node, the one or more intervening nodes, and the end node is operable to receive optical traffic in a number of multiplexed wavelengths from the optical network, drop a first copy of the multiplexed optical traffic from the optical network, and forward a second copy of the multiplexed optical traffic on the optical network. These nodes also forward the optical traffic in selected wavelengths of the dropped first copy for communication to one or more client devices associated with the node. The nodes further convert traffic received from one or more client devices of the node into client optical traffic in one or more wavelengths, passively add the client optical traffic to the second copy or to a modification of the second copy to form a combined signal, and forward the combined signal to the network.

摘要： In one embodiment, a method of passively adding traffic from a first optical network to a second optical network includes receiving ingress traffic from an optical ring of the first network at a node coupled to the first network, generating a first and second copy of the traffic, passively forwarding the first and second copies of the traffic, splitting the second copy of the traffic into multiple substantially identical copies, and filtering at least one of the copies of the second copy of the traffic into one or more constituent wavelengths. The method further includes selectively forwarding the signal in one or more constituent wavelengths of the second copy of the traffic to a node coupled to the second network, receiving the forwarded signal in one or more wavelengths at the node, and adding the forwarded signal in one or more wavelengths to an optical ring of the second network.

摘要： An optical amplifier includes an optical amplification medium, an excitation source to stimulate the amplification medium to output at least one wavelength gain peak, and a gain equalizer to equalize the output of the amplification medium such that gain is produced at wavelengths other than the wavelength gain peak. The gain equalizer may attenuate gain at the peak wavelength. The gain equalizer may equalize the output of the amplification medium such that gain is produced at wavelengths less than the wavelength gain peak. The optical amplifier may include both a gain equalizer and automatic level control circuitry to respectively maintain substantially uniform gain at wavelengths within an optical signal band and maintain constant output power.

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.
