“…Much attention has been directed to WDM-PON as an ideal solution in an access network in order to extend the capacity of networks in [19,20]. While the TDM-PON relies on a downstream wavelength and another upstream wavelength, the WDM-PON utilized multiple wavelengths so that 2 wavelengths are allocated to each user for down/ upstream transmissions, which leads to an increased transmission capacity in an access network.…”

“…On the other hand, because there are no direct channels (or routes) between the sub-networks (ONUs) in the conventional PONs such as E-PON, WDM-PON and so on, the local traffic between neighboring sub-networks need to take a long (non-optimal) path by way of the OLT [19,20]. That is, when an ONU 1 sends local traffic to a neighbor ONU 2, the local traffic takes a route such as the ONU1 ?…”

“…WDM-PON has other advantageous characteristics of protocol transparency, security and so on. However, it has not been considered as a practical access network solution because of the high system cost, compared to other PON techniques, including time-division multiplexing-PON (TDM-PON) [16][17][18][19][20] which have become popular optical access techniques for FTTH applications. It may be prudent to now reconsider the WDM-PON technique as a potential solution for the newly emerging applications if the high system cost can be shared by many subscribers as the immediate demand for high network performances cannot be met by other techniques at reasonable cost.…”

In this paper, an IP-based wireless access network is proposed, which is designed to support the hierarchical MIPv6 standard on the wavelength division multiplexed passive optical network access network in order to provide a fast and seamless handoff support. Two schemes for enhancing the mobility management are included in the proposed network's infrastructure support. Firstly, the local-link channels between sub-networks are provided to improve the mobility management efficiency for the mobile nodes roaming between neighboring subnetworks. Secondly, the early route optimization scheme has been applied, which optimizes the mobility management process between the corresponding node and the home agent (HA), resulting in reduced bandwidth waste and long end-to-end packet delays, as well as lowering the heavy burden on the HA. The performance of the proposed mobility management scheme has been evaluated in terms of handoff delays, packet losses and transmission costs.The superior performance of the proposed scheme has been verified and compared to other schemes.Keywords Mobile IPv6 (MIPv6) Á Hierarchical mobile IPv6 (HMIPv6) Á Handoff Á Wavelength division multiplexing (WDM) Á Passive optical network (PON)

Abstract-In this paper, we propose a novel WDM-PON architecture to support efficient and bandwidth-scalable virtual private network (VPN) emulation over both inter-PON and intra-PON. The virtual ring link for the VPN communications among ONUs is realized by using additionally low-cost optical passive components and OFDMA technology. Moreover, the downstream traffic wavelength is reused for the upstream traffic signal by using re-modulation technology. We report on a successful transmission of 10.7 Gbps OOK upstream and 10.7 Gbps DPSK downstream, together with 1.25 Gbps 16-QAM OFDM VPN traffic, over 20 km no-zero dispersion shifted fiber (NZDSF). Keywords-Optical access networks; virtual private network (VPN); orthogonal frequency division multiple access (OFDMA); passive optical network (PON)

“…To introduce WDM access networks, a wavelength-independent optical network unit (ONU), the colorless ONU, is the key technical issue. Some recently proposed WDM loopback access networks locate a WDM light source at the central office (CO) and each ONU includes an optical modulator [1][2][3][4][5][6]. For upstream transmission in these networks, a continuous wave (CW) light is distributed from the CO to each ONU, modulated, and sent back to the CO.…”
