Method of transmitting optical data packet signals in an optical wavelength-division multiplexing network

摘要

A payload time slot of a first optical signal and a simultaneously transmitted payload time slot of a second optical signal have synchronous beginnings at a transmission side. A guard-band time slot of the first optical data packet signal and a simultaneously transmitted guard-band time slot of the second optical data packet signal have synchronous endings at the transmission side. A chromatic dispersion difference affecting the signal s is compensated, by setting the time duration of the payload time slot of the second optical data packet signal and furthermore also the time duration of the successive guard-band time slot of the second optical data packet signal at the transmission side, such that the successive guard band timeslot of the first optical data packet signal and the successive guard band time slot of the second optical data packet signal have at least a pre-defined overlap at a receiving side.
