Abstract
The present invention relates to an adaptive and all-optical method for data packet rate multiplication compatible with multiple data rates and/or multiple communication protocols. By performing a real-time pulse width compression on an original electronic or optical packet from an end user or a network interface device, the method generates an optical packet having an identical rate with the original packet while the duration of each pulse being significantly reduced. Then, by eliminating any redundant idle time due to the pulse width compression, the method also shortens data period and thus makes the rate of packet multiplied. The present invention addresses the technical problem of limited data rate in EO/OE conversion as known in the prior art and solves fundamentally the interconnection and communication between networks or systems of different data rates and/or protocols. The method of the present invention thus enables the design of an ultrahigh rate all-optical communication system and network transparent in rate and protocol.
