Chirp cancellation method is proposed to reduce XPM effects in DWDM optical channels, which is executed by controlling the time delay and power of transmitted pulses. Simulation results verify the effectiveness of the proposed method.
In this paper, we propose the seamless handoff support scheme for broadband real-time services, which is based on the wavelength division multiplexing-passive optical network (WDM-PON) technologies and HMIPv6 in the wireless access network. Firstly, the proposed scheme provides fast and seamless handoff support through the proposed reliable and efficient… (More)
In this paper, we propose the power detection (PD)-based TDM-PON architecture, which is implemented for a hardware-based decentralized DBA (dynamic bandwidth allocation) among ONUs, without OLT's intervention to service. The proposed approach is characterized by a simple, fast and cost-effective operation on TDM-PON.
