Abstract:

Wave-guide function in multimode fiber is solved using central difference method to get the linearly polarized mode distribution and double integral is done to get the mode power distribution by laser inspirited. Two steps are the key to calculate the optical power transfer function (OPTF). At last equalization simulation is carried out and the results show that for 300-meter distance 4dB dispersion performance requirement of 10G Ethernet can be satisfied by using decision feedback equalization.

Key words: multimode fiber, intra-modal dispersion, optical power transfer function, electronic equalization
