Passive Optical Network (PON) is the most promising technology in optical access network, and the effective and reasonable upstream dynamic bandwidth allocation (DBA) is the key. This paper proposes a new software defined WDM-TDM PON frame that enable more users to share a single high-capacity fiber access as well as introduce a flexible DBA module to replace the hardware-configured DBA module. The...
A physical layer security enhanced orthogonal frequency division multiplexing (OFDM) passive optical network based on dimension-transformed chaotic permutation is proposed and experimentally demonstrated. In this scheme, a large key space is obtained by multidomain jointed Rossler permutation, and the corresponding complexity scale caused by multidomain encryption can be reduced through dimension-transformed...
We propose and experimentally demonstrate an ECDM-OFDM-PON with variable spreading factor (VSF), which endues the network with more flexible resource allocation. Bidirectional 9.22-Gb/s ECDM-OFDM signal with VSF are transmitted 75-km fiber successfully.
We propose and experimentally demonstrate a novel MAMSK-OFDM-PON. 5-Gb/s MAMSK-OFDM signal and 2.5-Gb/s upstream OOK signal is transmitted over 20km fiber successfully. The results show the prospect of this technology in future optical access networks.
We experimentally demonstrate a dynamic λ-OFDMA with selective DPSK overlaid, and multicast control is realized through an alternative LO. The 10-Gb/s P2P signal, 2.5-Gb/s overlaid and 1.25-Gb/s upstream signal are transmitted 25km fiber successfully.
We experimentally demonstrate a novel wavelength division multiplexed OFDM-PON architecture DPSK video overlaid. The 10-Gb/s 16QAM-OFDM P2P signal, 2.5-Gb/s DPSK video signal and 2.5-Gb/s OOK upstream signal have been transmitted over 20km fiber successfully.
