First Demonstration Of Optical-Mobile Cooperation Interface For Mobile Fronthaul With Tdm-Pon

To achieve cost-effective mobile fronthaul (MFH) with a time-division-multiplexing passive optical network (TDM-PON), we present a prototype optical-mobile cooperation interface, which converts mobile upstream scheduling information to transmission request information for the mobile upstream data that will arrive at each optical network unit (ONU). By basing bandwidth allocation on the request information converted by the interface, low-latency upstream transmission can be achieved on the MFH with the TDM-PON. We demonstrate the time spent for the conversion process in the prototype interface under various and practical conditions for the first time.
