Versatile Metro-Access Network Integrating FTTH, Enterprises, IoT and 5G Services

Bandwidth demands are increasing with a high dynamic shape, driven by high definition video, cloud-computing, business services, Internet of Things (IoT) and emerging next generation mobile networks like 5G. To support this variable pattern, reconfigurable capabilities are to be delivered to access and metro networks. Furthermore, considering wireless networks, a centralized processing in a Cloud-Radio Access Network (C-RAN) needs reconfigurable abilities to bring benefits to mobile systems with dynamic demands of huge bandwidth between Remote Radio Heads (RRHs) at base stations and Baseband Units (BBUs) at the central office. In this paper, we propose a versatile metro-access network integrating FTTH, enterprises, IoT and 5G services. To achieve a high sensitivity and bandwidth efficiency, we will use coherent transceivers and Ultra Dense Wavelength Division Multiplexing (UDWDM), which has been envisioned for future PONs and metro networks to support the increase of access traffic.
