WebNov 1, 2014 · Abstract In orthogonal frequency division multiple access-passive optical network (OFDMA-PON) uplink transmission with a direct detection system, the optical beat interference (OBI) noise is a... WebIn this paper, we demonstrate a complete suppression of coherent Rayleigh noise in a bi-directional fiber link using a modelocked laser transmitter. The noise suppression arises because optical beat interference at the receiver occurs mostly at frequencies beyond the receiver bandwidth, and cannot contribute to RF noise. Our results suggest that noise …

WebTheoretical and experimental investigation of direct detection optical OFDM transmission using beat interference cancellation receiver S. Alireza Nezamalhosseini, Lawrence R. … WebThis type of noise is called Optical Beat Interference (OBI) and it is dependent on the accumulated Chromatic Dispersion (CD) experienced transmission. This thesis establishes a new approach to reduce OBI by suppressing the optical carrier. The effect of OBI in the presence of FWM is also examined and analyzed. chin chin rathdowne

Handling OBI in RFoG Systems The RF over Glass (RFoG) technology offers Hybrid Fiber Coaxial (HFC) networks with high capacity potential and extends their life deep into … Beat In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones, beats can be readily recognized. Tuning two … See more In physics, interference is a phenomenon in which two coherent waves are combined by adding their intensities or displacements with due consideration for their phase difference. The resultant wave may have greater … See more Because the frequency of light waves (~10 Hz) is too high for currently available detectors to detect the variation of the electric field of the light, it is possible to observe only the intensity of an optical interference pattern.
