Radio Over Fiber for Picocellular Network Architectures

Journal of Lightwave Technology, 2007
We have studied RF transmission over various multimode fibers (MMFs) and a standard single-mode fiber, targeting picocellular networks for voice, data, and video applications. Bandwidth requirements of MMF links that are based on vertical-cavity surface-emitting laser (VCSEL) have been extensively studied.

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 ...

���������������� ���������������������� MAC ������ ������������ Radio over Fiber.:

2010
We present an agile and medium-transparent Medium Access Control (MAC) protocol for seamless and dynamic capacity allocation over both optical and wireless transmission media in 60GHz broadband Radio-Over-Fiber (RoF) networks. Medium transparency is achieved by means of parallelism between two simultaneously running contention periods and through ...
