The study reported here deals with the exploitation of perfluorinated graded index polymer optical fiber bandwidth to add further services in a home/office network. The fiber properties are exhibited in order to check if perfluorinated graded index plastic optical fiber (PFGI-POF) is suitable to support a multiplexing transmission. According to the high(More)
Integration of electrochemical capacitors with silicon-based electronics is a major challenge, limiting energy storage on a chip. We describe a wafer-scale process for manufacturing strongly adhering carbide-derived carbon films and interdigitated micro-supercapacitors with embedded titanium carbide current collectors, fully compatible with current(More)
We have performed a detailed study of four Perfluorinated Graded Index Polymer Optical Fiber (50/490, 62.5/490 and 120/490) issued from several manufacturers and designed to be used in short length (100m) small office/home office network operating at 850nm. We have used commercially available 850nm low cost XFP transceivers and have compared the power(More)
The integration of wireless and optical networks is a potential solution for increasing capacity and mobility as well as decreasing costs in the access network. Radio-over-fibre (RoF) or hybrid fibre radio (HFR) combines the capacity of optical networks with the flexibility and mobility of wireless access networks. We propose a downlink demonstrator for(More)
This work describes the different indoor applications and relative device requirements of the transmission of microwave or RF signals by optical fiber means. Systems are based on the picocell distribution scheme, which uses the remote antenna concept consisting in a base station, which optically feeds several remote antenna units. Two kinds of systems can(More)
