Power-over-fiber using double-clad fibers for radio-over-fiber systems

2014 19th European Conference on Networks and Optical Communications - (NOC), 2014
This work presents a power-over-fiber (PoF) using double-clad fibers (DCFs) for radio-over-fiber (RoF) systems. The DCF for the RoF link has a single-mode (SM) core and a multimode inner cladding; the SM core is used for both downlink and uplink transmissions of the optical RoF data signals, while the inner cladding is used for optical power delivery ...

Radio over fiber for mobile communications

2004 IEEE International Topical Meeting on Microwave Photonics (IEEE Cat. No.04EX859), 2005
Radio over fiber is becoming an increasingly important technology for the in-building wireless market. The dynamic range requirements and optimum choice of laser are identified for this application. Furthermore, a novel architecture based on switched radio over fiber is proposed, which gives important benefits in terms of design, installation and ...

Architectures and Algorithms for Radio-Over-Fiber Networks

Journal of Optical Communications and Networking, 2018
To serve futuristic applications, wireless access with a wired-like connectivity is required. To accomplish this goal, we propose a design for a flexible radio-over-fiber (RoF) network, where we optimize the RoF network for the right choice of subcarrier modulation scheme.

Radio over fiber in multimedia access networks

Proceedings of the 1st international conference on Access networks - AcessNets '06, 2006
Dominant broadband access technologies today are Digital Subscriber Line (DSL) and hybrid fiber coaxial (HFC) networks. DSL leads, with global subscribers exceeding 100 million, while cable-modem subscribers worldwide total 55 million in 2005 [1]. Recently, fiber-to-the-home (FTTH) and fiber-to-the-curb (FTTC) scenarios are also on the rise.

Fiber-to-the-home/radio-over-fiber transport systems

2009 14th OptoElectronics and Communications Conference, 2009
A directly modulated fiber-to-the-home (FTTH)/radio-over-fiber (ROF) transport system based on −1 side mode injection-locked and optoelectronic feedback techniques is proposed and demonstrated. Low BER values and clear eye diagrams were achieved in our proposed systems.

Optimization of the Use of Radio Resource of Radio-Over-Fiber Access Networks

2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010
In this paper, we introduce a radio resource optimization model for Radio-over-Fiber (RoF) access networks. We propose a mixed integer programming model to minimize the network cost while providing service to all mobile users. The proposed architecture arranges cells in a multi-layer fashion, with cells in each layer providing different coverage radius.

DWDM aspects of radio-over-fiber

LEOS 2000. 2000 IEEE Annual Meeting Conference Proceedings. 13th Annual Meeting. IEEE Lasers and Electro-Optics Society 2000 Annual Meeting (Cat. No.00CH37080), 2002
Fixed wireless access provides an attractive option for 'last mile' delivery of broadband services in urban areas. The availability of spectrum in the millimeter-wave (mm-wave) band allows delivery of digital voice, video and data services. Optical transport may play an important role in point-to-multipoint (PMP) fixed wireless access systems by ...

Radio over Fiber for Broadband Communications

2009
The high capacity offered by the optical fiber, combined with the mobility and the flexibility of wireless access, either fixed or not, provides an efficient approach to alleviating the requirements posed by the envisaged provision of any-service, anytime and anywhere, next generation communication networks.

Analog radio-over-fiber solutions in support of 5G

2018 International Conference on Optical Network Design and Modeling (ONDM), 2018
We introduce Centralized (C-RAN) architectures combined with analog optical transport schemes to realize high-speed lanes between BBU pool and RRHs. The DSP-enabled architecture relies on the use of a powerful digital engine supporting data plane functions for both fiber-wireless parts.
