Abstract:
Unprecedented levels of device connectivity and the emergence of futuristic digital services are driving fundamental changes to underlying fixed and wireless data transport networks. Projected bandwidth requirements, coupled with in-creased network centralization and virtualization, will lead to the convergence of data-center, fixed and wireless systems, and a greater onus being placed on the optical routing/transport portion of these networks. Such converged networks will require the development of optical technologies capable of servicing a multitude of network user types. In this work, we propose the use of a Silicon Photonic (SiP) space-and-wavelength selectives witch fabric as a flexible wavelength provisioning platform for converged optical networks. The envisaged converged network is presented, and an experimental test-bed which demonstrates flexible Cloud Radio Access Networking (C-RAN), using a 4×4micro-ring resonator based switch, is described. Successful pro-visioning and transmission of Wavelength Division Multiplexed(WDM) based analog Radio-over-Fiber (RoF) services, over 10km of fiber, in the converged test-bed is demonstrated and evaluated in terms of the received Bit Error Rate (BER) and Error Vector Magnitude (EVM). Furthermore, the wavelength multi-casting capabilities of the SiP switch is shown to enable dynamic resource allocation in the optical domain, and this is highlighted through the experimental implementation and evaluation of two C-RAN use cases - representing high and low mobile traffic demand scenarios.
