    Abstract: Laser pulse shaping techniques produce tailored laser pulse spectral output. The laser pulses can be programmed to have desired pulse widths and pulse shapes (such as sub-nanosecond to 10 ns-20 ns pulse widths with 1 ns to several nanoseconds leading edge rise times). Preferred embodiments are implemented with one or more electro-optical modulators receiving drive signals that selectively change the amount of incident pulsed laser emission to form a tailored pulse output. Triggering the drive signal from the pulsed laser emission suppresses jitter associated with other stages of the link processing system and substantially removes jitter associated with pulsed laser emission build-up time.

    Abstract: A method of aligning optical data communication channels between system functions comprises: emitting an array of light beams from a corresponding array of data emitters in response to electrical data signals generated from a first system function; emitting light beams from two control emitters in response to electrical control signals generated from the first system function; receiving light beams from the data emitters by a corresponding array of data detectors to form an array of data optical communication channels; conducting electrical data signals reproduced from the received data emitter light beams to a second system function; receiving light beams from the two control emitters by two control detector sections to form two control optical communication channels; conducting electrical control signals reproduced from the received control emitter light beams to a second system function; monitoring a multiplicity of light detectors of each of the two control detector sections to determine an offset in optical channel alignment; and controlling the optical channel alignment based on the determined offset.

    Abstract: A method of controlling traffic forwarding in a Provider Backbone-Traffic Engineered (PBB-TE) network. A protection group (PG) is defined, and including N working Traffic Engineered Service Instances (TESIs) and M protection TESIs. An Automatic Protection Switching Protocol Data Unit (APS PDU) is defined, which includes information defining at least a state of the protection group. This APS PDU is forwarded only through the protection TESI(s).
