摘要： According to an aspect of an embodiment, a method of modeling an optical signal transmission path may include obtaining first transmission characteristics of an optical signal transmission path within an optical network based on a parameter of the optical network and randomly changing states of polarization of an optical signal within the optical signal transmission path. The method may also include obtaining second transmission characteristics of the optical signal transmission path based on the parameter and a first fixed state of polarization of the optical signal. The method may also include correlating the first transmission characteristics with the second transmission characteristics to obtain an effective state of polarization of the optical signal. A simulation of the optical signal transmission path based on the parameter and the effective state of polarization of the optical signal may produce transmission characteristics that may approximate the first transmission characteristics.

In one embodiment, a method and system for a data centric architecture in an optical network includes an optical ring. A number of local nodes are coupled to the optical ring and are configured to receive traffic at a receiving wavelength by optically broadcasting with electrical tag discrimination.

A data center node is coupled to the optical ring and operable to receive traffic from the local nodes, sort at least some of the traffic based on the destination of the traffic, and transmit the traffic at the receiving wavelength to the destination.

摘要： A method for compensating for optical dispersion in an optical signal includes receiving an optical signal comprising a plurality of channels. The information being communicated in a first set of channels is modulated using a first modulation technique, and the information being communicated in a second set of channels is modulated using a second modulation technique. The method also includes compensating for optical dispersion in the optical signal such that dispersion compensation for the first set of channels is complete and such that dispersion compensation for the second set of channels is incomplete. In addition, the method includes splitting the optical signal into a first copy and a second copy, terminating the second set of channels in the first copy, performing additional dispersion compensation on the second copy such that dispersion compensation for the second set of channels is complete, and terminating the first set of channels in the second copy.

摘要： An optical network includes at least one Level 1 network that includes a number of interconnection nodes and one or more Level 2 networks that each include one or more access nodes. The one or more Level 2 networks are each coupled to the Level 1 network via at least one interconnection node. One or more of the access nodes are each operable to add upstream traffic to the associated Level 2 network in a sub-wavelength, each sub-wavelength comprising a portion of a wavelength associated with the Level 1 network. Furthermore, one or more of the interconnection nodes are each operable to receive upstream traffic from a number of access nodes in a number of sub-wavelengths, process the upstream traffic in the sub-wavelengths as traffic in a single wavelength associated with the Level 1 network, and forward the upstream traffic from the access nodes in the single wavelength on the Level 1 network.
