摘      要：Driven by ZTE and other telecom vendors and operators in order to meet the ever increasing bandwidth demand from fixed optical network users and mobile backhaul/fronthaul services, the latest next generation passive optical network(NGPON2) is being standardized by Full Service Access Network(FSAN) and International Telecommunication Union(ITU-T) which consists of two separated sub-systems, hybrid time- and wavelength-division multiplexing PON(TWDM-PON) and point-to-point wavelength- division multiplex(Pt P WDM). The TWDM-PON will be used for traditional residential, business and wireless backhaul services which are not sensitive to time delay and delay variation, whereas the Pt P WDM is mainly used for emerging wireless fronthaul service which is very sensitive to the time delay and time delay variation. However, as a main international standards contributor, ZTE thinks for those operators who offer multiple-level of services to both residential, business and mobile backhaul/fronthaul users, this obviously raises significant economic and power concerns by demanding to deploy two separated systems. Therefore, in this paper, for the fi rst time, ZTE proposes a new converged optical and wireless integrated network architecture and topology by applying orthogonal frequency division
