This paper proposes a novel approach to achieve monitoring and control of modern substations using advanced computer communication and control technology. The proposed approach is based on a code division multiple access (CDMA) and interleave division multiple access (IDMA) system joining with optical-fiber communication technology to realize the utility infrastructure of Smart Grid. Recently, owing to the rapid growth on optical-fiber communication, it can offer standardized communication technology for wide-area, metropolitan-area, and local-area networks. Moreover, optical-fiber communication technologies offer not only significant benefits on connection among different CDMA-IDMA systems such as rapid deployment, higher baud rate (equal or higher than 14 Tb/s), enhanced bandwidth, less bit error rate (equal or less than 10 -9 ), less optical-amplifier quantities, reduced interference among them, lower signal attenuation, etc. but also the advantages of being more suitable for remote-end applications in Smart Grid environment. With spreading spectrum modulation and demodulation combing encoding, it can be used to transmit data and images over power lines to accomplish opportunities and challenges in the effort on comparisons and assure safety, security, and reliability in order to achieve reliability and demand efficiency for modern substations of the utility system as a supervisory control and data acquisition (SCADA) system.

“…Recently, different multiple access techniques have been proposed for NG-PONs e.g., wavelength-division multiplexing (WDM), optical code-division multiple-access (OCDMA), orthogonal frequecny-divison multiple-access (OFDMA), and interleaved frequecny-divison multiple-access (IFMDA), and optical interleave-division multiple-access (OIDMA).

“…In [7], performance of both non-coherent OIDMA and OCDMA is compared via simulations. Although the comparison itself is interesting, it is based on Matlab simulations where the simulation of some optical components was ignored, and many aspects were not considered: fiber length, fiber impairments, ONU launch power and user bit rate.…”

Coherent optical interleave-division multiple-access (OIDMA) has been recently proposed for next generation passive optical network (NG-PON) systems. In this paper we present a performance evaluation and comparison of coherent OIDMA and coherent optical code-division multiple-access (OCDMA) PONs in terms of ONU launch power, PON reach, bit error rate (BER), user bit rate, and number of users. Results reveal that OIDMA out-performs its counterpart in all aspects. Particularly, high user loading compared to OCDMA.
