摘要： The invention relates to an optical modulator control system implemented in an optical burst mode transmitter, said control system comprising means for measuring a plurality of optical power sample values and associated optical wavelength data values from a modulator at a first sampling rate, wherein an average power table is generated from said values for each sample period and stored in a memory. The control system also comprises means for performing a control error calculation from two or more stored average power tables at a second sampling rate to calculate a single error value to provide gain and/or bias control signals, wherein the second sample rate is sampled at a slower rate than the first sample rate. The control system described optimises the modulator performance over temperature and lifetime in an optical network.

摘要： The invention provides a control layer for an Optical Burst Switch (OBS) system, said system comprising at least one stage configured with a closed optical burst switch addressing scheme and one or more ports for sending or receiving data packets. The control layer comprises a control addressing scheme independent of the closed optical addressing scheme and means to provide interconnectivity for each port with every other port. In one embodiment there is provided a closed optical burst switch ring network. The control layer encapsulates or maps the optical data at a port into an independent packet format and passes the independent packet format into a queuing system for transmission by the optical burst switch ring network to a destination port.

摘要： The invention provides a burst transmission optical fibre wavelength routed ring network and method comprising a plurality of nodes on a network ring where each node can drop and add a wavelength. The network has a control means to control the wavelength to be transmitted on the network ring in a burst transmit mode from each node over a scheduling interval. The invention provides a random generator for generating a plurality of gap intervals over the scheduling interval, such that the gap intervals allow for wavelengths from different nodes to transmit wavelengths in said gaps to achieve a fair access to bandwidth and fair latency in the ring network.
