    Abstract: A system and method for generating, based on optical network topology information, an optical model to represent an optical network; provisioning a new optical connection within the optical network: determining, using the optical model, a first bit error rate (BER) of the new optical connection; determining, using the optical network providing the new optical connection, a second BER of the new optical connection; determining, based on the first and the second BER, a BER excursion parameter of the new optical connection; training a margin allocator based on the BER excursion parameter of the new optical connection, and the first BER of the new optical connection; comparing the first BER of the new connection and a required optical margin to a threshold to determine a reliability of the new optical connection; and allocating, using the margin allocator, the required optical margin for additional optical connections of the optical network.

    Abstract: Methods and systems are provided for monitoring a network link in an optical transport network. The method includes injecting a first level of added noise to the data stream at the receiver for a first period. The method further includes calculating a first bit error rate (BER) for the first period. The method also includes injecting a second level of added noise to the data stream at the receiver for a second period, the second level of added noise different than the first level of added noise, wherein the first and second periods do not overlap. The method further includes calculating a second BER for the second period. In addition, the method includes determining a characteristic of the network link based on the first BER and the second BER.

    Abstract: An opto-electronic module used in optical networking may be implemented using two different thermal zones. A first thermal zone at a first temperature may be used for an optical module. A second thermal zone at a second temperature may be used for an electronic module. The first temperature may be different from the second temperature. As a result, a physical dimension of the electronic module may be reduced in comparison to using a single thermal zone for the opto-electronic module.

    Abstract: A matrix M is used to determine groups of potential regenerator placements and obtain potential end-to-end optical paths by selecting desired sequences of regenerators. Then, a hierarchical guided search may be employed to efficiently select desired N-tuple disjoint optical paths from the potential optical paths. The hierarchical guided search may employ a search graph and a search tree to guide the search and to eliminate candidate nodes and optical paths early in the search process.

    Abstract: Methods and systems are provided for optical signal transmission using span-wise spectrum management. The method includes transmitting a first optical signal at a first wavelength by a control system. The first optical signal has a first optical path distance. The method further includes determining a first guard band requirement for the first optical signal, and transmitting a second optical signal by the control system. The second optical signal has a second optical path distance. The method includes determining a second guard band requirement for the second optical signal, and placing the second optical signal spectrally adjacent to the first optical signal by selecting a second wavelength. The second wavelength is selected to satisfy the first and second guard band requirements.
