This paper describes the cost reduction strategy followed by a group of five Mexican restaurant enterprises located in the Monterrey metropolitan area. With this new alliance, a new integrated raw material supply system was required to take advantage of the synergies and economies of scale achieved on raw material acquisition and storage and transportation activities. To determine the new system i...Show More
With the optical frequency multiplying technique, high-capacity radio-over-multimode fiber networks can be realized for in-building applications. Dynamic wavelength routing provides extra network flexibility for e.g. delivering capacity-on-demand, and can be realized with optical wavelength conversion.Show More
Microwave to mm-wave radio carriers are commonly employed for creating high-capacity picocell wireless networks. Advanced radio-over-fiber (RoF) techniques can efficiently generate and transport such carriers, and deliver them to simplified antenna stations. As in in-building networks multimode fiber is predominantly used, adequate radio-over-multimode fiber (RoMMF) techniques are required to over...Show More
In this paper, we analyze, for the first time, the eminent role of optical transparent networking in personal networks. We show how an optical access network mitigates many issues with respect to connectivity and mobility management. A concrete personal network user-scenario deduces requirements for such an architecture. A combination of passive optical network, optical code-division multiple acce...Show More
A theoretical signal analysis is presented to demonstrate the robustness of optical frequency multiplication (OFM) against modal dispersion impairments in radio-over-multimode fiber links. The predicted system robustness is also experimentally demonstrated with the generation and transmission of 60 Mb/s and 120 Mb/s 64-QAM radio-frequency signals at 24 GHz over three different 4.4-km-long multimod...Show More
Radio-over-fiber technologies enable efficient provisioning of broadband wireless services both in access and in in-building networks, in particular when combined with flexible optical routing and dispersion-robust RoF transport techniques, such as optical frequency multiplying.Show More
With the advent of opening up 60 GHz Radio with 5 GHz of available spectrum, many bandwidth-hungry applications can be supported. The immediate concern, however, is the constraint on the line-of-sight transmission as well as the short transmission range of signals. As a result, in an indoor network, a mobile user might experience frequent breaks or losses of connection when one moves from one cell...Show More
We present a full-duplex multimode wavelength-division-multiplexing ring network for the distribution of broadband wireless services. It successfully combines the use of all-fiber wavelength selecting multimode add/drop multiplexing nodes with a radio-over-multimode-fiber technique that is robust against modal dispersion impairments in multimode fiber links, and allows a reliable delivery of wirel...Show More
Optical fibre is marching fast towards the user's doorstep, as witnessed by the many new Fibre-To-The-Home installations. The next challenge is to disclose the power of optical communication inside the home, so to bring the full broadband potential to the end user. The presentation will describe the latest advances in our research into low-cost in-home techniques, encompassing techniques for servi...Show More
We present a physical layer design for radio-over-fibre links comprising bidirectional RF transmission, increased cell capacity allocation, multi-standard support, remote LO delivery and in-band control channel for dynamic radio link adaptation and remote antenna controlling.Show More
Employing the optical frequency multiplication method, we present an experimental performance analysis of the generation of microwave carriers up to 40GHz and their transmission over a 4.4km multimode fiber link. Also, 16QAM and 64QAM radio signals up to 20MS/s symbol rate are recovered successfully in the 24-30GHz band after 4.4km multimode fiber transmission, complying with the transmitter const...Show More
This paper addresses the issues of designing an infrastructure to support seamless in-building communication at the 60 GHz band. Recently, the 60 GHz band has received much attention due to its 5 GHz of available spectrum. However, the propagation of signals in this band is strongly hindered by attenuation and line-of-sight requirements. The situation gets worse in the in-building environment wher...Show More
Employing the optical frequency multiplication method, the theoretical modal bandwidth limitation of multimode fiber (MMF) can be overcome in radio-over-fiber links. The principle is analyzed theoretically and supported experimentally by generation and transmission of microwave carriers up to 40 GHz and 16- and 64-level quadrature-amplitude-modulated (QAM) radio signals in the 24- to 30-GHz band o...Show More
Employing optical frequency multiplication, we demonstrate experimentally the simultaneous delivery of different 64QAM radio signals at 5.8 and 17.7 GHz after 4.4 km of multimode fiber in a single radio-over-fiber link. We also propose a flexible mechanism for the dynamic radio link adaptation, and the simultaneous transmission of an in-band control channel with the wireless data channels for powe...Show More
We demonstrate an all-optical label and payload processor based on nonlinear optical signal processing with semiconductor optical amplifiers. The processor separates the label and the payload, and generates a synchronization pulse, used to control the label comparison operation in an all-optical routing node.Show More
We demonstrate experimentally the feasibility of a wavelength-multiplexed radio-over-fiber distribution antenna system in a star-tree configuration based on optical frequency multiplication and employing GCSR tunable lasers for the generation of the swept light source.Show More
We experimentally demonstrate a FSK-WDM to IM-OTDM conversion system, based on a MZI wavelength converter. The FSK channels data rate is 500 Mbps, while error and power penalty free conversion to 5 Gbps IM-OTDM is reported. Operation at 10 Gbps is also shown.Show More
We propose a bidirectional radio-over-fiber link consisting of an optical downlink transmission employing the optical frequency multiplication principle, a remote local oscillator (LO) generation, a remote down-conversion of the radio-frequency uplink signals, and an optical uplink transmission employing intensity modulation-direct detection. Experiments demonstrate the optical up-conversion of 64...Show More
