A scheme for transportation of information with minimum Rayleigh backscattering (RB) noise to the multi-users by employing Qdash laser diode as a source is designed and evaluated. In this paper, employing DPSK, MMW, 16-QAM OFDM, and 32-QAM OFDM techniques, the data rates of 4X10 Gbps are transmitted simultaneously over 50 km single mode fiber (SMF), plus 15 m wireless link, 50 m FSO link, 10 m wireless respectively. Four selective self-injection locked modes of Qdash laser are utilized as optical carriers for downstream (DS) and upstream (US) transmission. To ensure the matter of mitigation of RB noise, which mainly arises due to the transmission of light-wave of same wavelengths in bidirectional transportation, the carrier signals of different wavelength are used for modulation and remodulation in OLT and ONU. Besides being a strong support to increase the tolerance level against RB noise, this architecture is capable to transmit less noisy information wirelessly in RF sensitive areas too. The constancy of the proposed architecture is evaluated by very low power penalty, clear constellation, prominent eye opening, low bit-error-rate and low error vector magnitude. Therefore, the proposed architecture could be promising alternative not only due to the scheme for mitigation of RB noise but also be a potent in the field of applications of the communication world to provide less noisy information to the multi-users (wired/wireless/FSO).
