Time-Interleaved Phase Remodulation to Enable Broadcast Transmission in Bidirectional WDM-PONs without Additional Light Sources
Time-Interleaved Phase Remodulation Enable Broadcast Transmission Bidirectional WDM-PONs without Additional Light Sources
2011/5/21
Time-interleaved phase remodulation is proposed to realize broadcast transmission for WDM-PONs. Simultaneous transmission of 5-Gb/s bidirectional unicast data and broadcast data is demonstrated at the...
Influence of Broadcast Traffic on Energy Efficiency of Long-Reach SARDANA Access Network
Influence Broadcast Traffic Energy Efficiency Long-Reach SARDANA Access Network
2011/5/21
We describe reach extension in SARDANA TDM/WDM PON and show that energy efficiency of SARDANA increases when increasing the amount of broadcast traffic. 10G point-to-point optical access networks prov...
Experimental Demonstration of a Cost-Effective Broadcast Overlay for a Commercial WDM PON
Commercial WDM PON Cost-Effective Broadcast Experimental Demonstration
2011/5/18
We demonstrate a simple cost-effective broadcast overlay for WDM PON which uses a single directly modulated superluminescent diode to deliver an RF video or baseband gigabit-Ethernet service to all 32...
Broadcast Capable 40-Gb/s WDM Passive Optical Networks
Broadcast Capable WDM Passive Optical Networks
2009/7/17
A novel architecture for broadcast capable high-speed WDM-PONs is proposed. 40-Gb/s downlink and 10-Gb/s broadcast are demonstrated to transmit simultaneously on the same set of wavelength channels. A...
Along with progress in digital broadcast waves and popularization of the Internet, broadcast service has continued to evolve past the concept of conventional analogue broadcasting. In conjunction with...
Cost-effective WDM-PON for Simultaneously Transmitting Unicast and Broadcast/multicast Data by superimposing IRZ signal onto NRZ signal
Cost-effective WDM-PON Simultaneously Transmitting Unicast Broadcast/multicast Data
2008/8/3
We propose a novel WDM-PON broadcast/multicast architecture that superimposes inverse-RZ signal onto NRZ unicast signal. Multicast control is realized through extinction ratio adjustment of the NRZ si...
