Article
Full-text available
In this paper, we propose and experimentally demonstrate a multiuser wavelength-division-multiplexing passive optical network (WDM-PON) system combining with orthogonal frequency division multiple (OFDM) technique. A tunable multi-wavelength optical comb (MOC) is designed to supply flat optical lines for assisting the configuration of the proposed...
Article
Full-text available
An efficient and unambiguous failure monitoring and protection mechanism is proposed in long-reach passive optical network (LR-PON). Optical code domain reflectometer by optical coding scheme is utilized. Improved optical encoders are placed centrally in optical distribution network and at both sides of each remote node to monitor all links and nod...
Article
Long-reach passive optical networks (LR-PONs) allow extending the distance between central office (CO) and end users to hundred kilometers. Due to its high capacity and large coverage, LR-PON becomes increasingly vulnerable to various failures. In this paper, optical code domain reflectometer (OCDR) and optical time domain reflectometer (OTDR) loca...
Article
A monitoring mechanism combining the advantages of a monitoring trails scheme and an optical coding scheme is proposed; the mechanism can be used in a metro-access network. Optical encoders are centrally placed in an optical distribution network and at both sides of each remote node, which makes for much simpler installation and smaller management...
Article
Network survivability and protection mechanisms are very important and necessary in optical networks. The long-reach passive optical network (LR-PON) proposed in this paper extends the access network to hundreds of kilometers, and it can support more optical network units by wavelength division multiplexing technology. We propose an efficient prote...
Article
We report on an OFDM-RoF-PON system based on novel optical coupling single-sideband (O-SSB) modulation for one wavelength carrying one baseband and two radio frequency (RF) signals. The impact of nonlinear distortion consisting of harmonic distortion (HD) and intermodulation distortion (IMD) in this system is theoretically investigated. Transmissio...
Article
The elastic optical network is a novel idea that is targeted at realizing flexible bandwidth allocation according to diverse traffic needs and requirements. Meanwhile, with the increasing demand of data rates in optical access networks, it is urgent to upgrade the current passive optical networks (PONs) through more elastic approaches. In this pape...
Article
The authors report on a WDM–OFDM–RoF system based on a novel optical coupling tandem single-sideband (O-TSSB) transmitter for one wavelength carrying two radio frequency signals. The impact of nonlinear distortion consisting of harmonic distortion and intermodulation distortion in this system is theoretically investigated and it has been found that...
