摘要
Building low-latency and high-capacity optical networks is vital for new high-speed cellular technologies.Coherent wavelength division multiplexing passive optical networks(WDM-PONs)are expected to play a key role in these applications.In this article,an overview of PON technologies for the 5 th generation(5 G)transport systems has been given.Moreover,a modified scheme based on coherent WDM-PON has been investigated using a dual polarization quadrature phase shift keying(DP-QPSK)transceiver.The aim of the scheme is to build a 1600 Gbit/s network that will be used in the construction of the transport architecture of 5 G and beyond cellular networks either in mobile front haul(MFH)or mobile back haul(MBH).The results indicate that the proposed scheme offers a promising solution for future 5 G transport systems.
