  29. Recent Research Activities of WDM-PON in Korea

  30. Recent Research Activities of WDM-PON in Korea MDU (Multiple Dwelling Unit environment) remote node (ONU) is outdoor and powered up to 24 user port at ONU SDU (Single Dwelling Unit environment) wavelength is splitted

  31. A hybrid-amplified PON with 75-mn downstream bandwidth, 60 km reach, 1:64 split and multiple video services Fig. 7. Experimental setup of extended and service-upgraded PON using an extender box SOA-Raman Hybrid Amplifier (SRHA) Ultra broadband gain (up to 80-nm bandwidth)

  32. A Cost-Effective WDM-PON Configuration EmployingInnovative Bi-directional Amplification Fig. 8. Bi-directional Amplifier Fig. 9. System Architecture After 100-km SSMF transmission, the powerpenalty for all channels at 10Gbit/s is less than 0.8 dB.

  33. Experimental upstream demonstration of a long-reach wavelength-converting WDM-PON with DWDM backhaul Fig. 10. System Architecture • Optical transmitter with precise wavelength control needs thermal control. • Increase cost of ONU. • Un-cooled laser is cheap, but introduces wavelength drifting.

  34. Optical VPN Connecting ONUs in Different PONs Fig. 11. VPN across different PONs VPN can only connects ONUs of the same color.

  35. Economic Evolution from EPON to WDM-overlaid PONEmploying a Wavelength Conversion Node Fig. 12. System Architecture Fig. 13. Structure of RN • Uniform ONU, working on the same upstream wavelength. • Smooth upgrade from EPON Powered outdoor WCN
