3-Channel DPSK - Space Division Multiplexing System with Equalization in Few Mode Fiber for Triple Play Services

Abstract

The significant increase in intelligent devices with real-time applications calls for high capacity heterogeneous wireless networks with a high-speed optical backbone. In this paper, a space division multiplexing (SDM) system is designed for Internet-of-Things by enabling the distribution of triple play signals from one location to another remote location. The SDM system is designed in conjunction with equalization based on minimum mean squared error (MMSE) to alleviate inter-symbol interference. The MMSE-based SDM system is simulated for 1, 2 and 3 channels, each channel transmitting 10 Gbps data for a distance of 1300 meters. The data is carried by different linearly polarized modes, each through a few mode fiber at a wavelength of 1527.99 nm. It is shown that the convergence time using MMSE is improved compared to previous algorithms with satisfactory eye diagrams.
