Paper Abstract

Here optical ray locus method has been employed to analyze the transmission of optical pulse in multi-mode fibre. Combined with training bits, we suggest a new method for MGDM (Mode Group Division Multiplexing), which calculates the energy focus for each mode on its transmitting direction from the optical ray locus. In addition, photodetectors will be placed in various places to measure the signals, contributing to avoid the energy coupling among different modes. After this, we transmit different training bits of each mode and eliminate the energy coupling on the receiver, which consequently generates a new method enabling us to independently modulate signals in each particular mode for the multi-mode fibre. Our simulations present the possibility of this method for two mode group transmitted in 850nm wavelength for the length of 100m at the bit rate of 10Gb/s.
