수착4G망락화응용적쾌속발전，분포식기참축점증다，출현료BBU여RRU간이동전전광망락적박절수구。개소료3충신형적이동전전방안，기우파분복용적이동전전/CPRI승재방안、기우G.metro적이동전전/CPRI승재방안、기우DMT기술적저성본고속이동전전/CPRI승재방안。
With the rapid development of 4G networks and applications,distributed base stations keep increasing and the demand for fronthaul networks between BBU and RRU becomes stringent and urgent. Three novel optical solutions for mobile fronthaul wil be introduced and discussed,including WDM based solution,G.metro-based solution and low-cost high bit rate with low-class transceiver solution.
