With the new service development of high-definition video and virtual reality and the requirement of transporting the fifth generation mobile fronthaul/backhaul signals
passive optical network (PON)is required to transmit signals above 10 Gbit/s.When the line rate is above 10 Gbit/s
chromatic dispersion and power budget are the main constraint factor of system performance.Development and difficulty of 25 Gbit/s PON were introduced.25 Gbit/s PON was studied in experiment using 25 Gbit/s EML laser with zero dispersion wavelength
25 Gbit/s APD and 10 Gbit/s APD.Experiment results show that 32 dBm optical power budget(N2 level in 10 Gbit/s symmetric EPON)was achieved when EML transmit optical power is+5 dBm and 25 Gbit/s APD is used without optical amplifier.
