In this paper, we propose a landing and a take-off assistance network architecture based on optical wireless technologies combining visible light communication (VLC) and free space optics (FSO). The network is composed of LED sensors that are used to collect information about the state of the runway and relay it using VLC communication to two gateways that will recover the sensed information and transmit...
The all-optical switching node implementations are limited by the lack of optical memory. We present an optical switching node based on all-optical buffering. We propose the organization of the all-optical switching node in four blocks: input block, control block, buffering block and switching block. The virtual memory based on the two loops architecture implements the multi-wavelength concepts to...
