METHOD AND SYSTEM FOR WDM TRANSMISSION WITH CHROMATO-TEMPORAL CODING

摘要

The invention relates to a sender and a receiver for an optical telecommunication system of WDM type. The sender uses a chromato-temporal coder (325), which with each block of symbols to be transmitted associates a code matrix, each element of the matrix corresponding to a wavelength, a use of the channel and a direction of polarisation. The sender comprises a plurality of modulators (321), each modulator modulating a laser beam at a wavelength during a use of the channel by means of an element corresponding to the matrix of the code. The beams thus modulated are multiplexed (330) on an optical fibre (240).
