摘要： A method for transparently transporting a multiplicity of data formats (TDM, frame, packet, cell, etc.) and bit rates in a deterministic manner over an optical telecommunications network facilitates purely photonic aggregation, separation and switching of granular, sub-wavelength capacity of bandwidths less than the line rate capacity. The sub-rate of the optical transport on a given optical frequency between network edge components uses time-slot based TDM channels that can be optically bursted across different wavelengths using wavelength hopping to allow all-optical switching of the channels between different signal paths in the optical switch nodes, on a time-slot-by-time slot basis using WDM to reduce the probability of blocked connections. The connection management of these wavelength hopping optical TDM bursts, (referred to as waveslots herein) is done using a connection protocol that employs conventional "least cost" path calculation algorithms to identify target connection routing through the optical network. A path integrity process ensures capacity, link removal and recalculation in cases of blocked connections. The time slot and wavelength map can be represented as a two dimensional matrix. Availability calculations can be done using simple matrix logic operations. The capability of the network to reconfigure and rearrange itself is maximized by the use of wavelength hopping. A full optical connection oriented bandwidth mechanism for management of that granular capacity is provided.

摘要： This disclosure applies to an improvement on conventional optical transmitte r architecture which allows the production of bursts of data signals with accurate selectable optical frequency within the target optical band. The invention overcomes the limitation caused when the monitor and feedback circuits do not provide sufficient control within the required time. A key aspect of this invention is the ability to ensure the output frequency is well controlled, even for rapid changes in output frequency, as in packet on wavelength systems. Two approaches are discussed: one for cases when the laser cannot be tuned withi n an allowed switching time, and one which applies when the laser can be tuned sufficiently quickly but requires on-going stabilization. The second approach may be used to improve the performance of the first approach . The first approach, in which a single laser cannot tune accurately within the required time, makes use of multiple lasers implemented with an appropriately fast optical switch to select the desired laser, each laser being tuned and locked on the frequency required for the packet it will address while an other is (or others are) transmitting. In the second approach, in which a single laser can be tuned to the nominal frequency during the transition time, the implementation improves the initial spectral quality and frequency accuracy on switching to a new frequency through: -setting the initial frequency as determined by a set of parameters in a table, - improving the output quality during the data transmission, -updating the table parameters based on the changes necessary to improve the signal. The second approach is particularly appropriate for rapid cyclical requirements for a particular wavelength, as the conditions for any wavelength may be nominally unchanged from cycle to cycle . If the tunable lasers cover only a fraction of the desired optical band, multiple lasers may be operated in paralleled to provide full coverage of the wavelength band, and combined with a fast optical switch, while being controlled with either of the two control approaches. This disclosure also applies to the use of such rapidly tuned optical sources to provide data units, frames or packets where each data unit can be of arbitrary frequency within a set of operational frequencies.

摘要： A data format and control protocol for a communication system is presented which allows purely photonic connections between network edge components. The format uses time slot based TDM channels to allow all optical switching of the channels between different signal paths in the switch nodes, and time slot by time slot WDM to reduce the probability of blocked connections. The connecti on protocol uses conventional 'least cost' path calculation algorithms to identify target connection routing through the network, a path integrity process to ensure capacity, and link removal and recalculation in cases of blocked connections. The time slot and wavelength map can be represented as a two dimensional matrix. Availability calculations can be done using simple matrix logic operations. System operation with bands of optical wavelengths is discussed.
