“…Some of the channels used to transmit data include coaxial cable [35,[60][61][62], fibre-optic cable [63][64][65][66] and wireless communication [67][68][69][70]. Coaxial cable has a good bandwidth, low error rate and relatively low resistance.…”

“…A new and simple liquid refractometer based on multiple total-internal reflections in heterodyne interferometry has already been shown [15]. Fibre-optic refractometers with intensity-type transducer which can operate remotely via long fibre-optic cables have been presented [16]. This paper describes a microcontroller-based instrumentation system to measure the RI of an unknown liquid using an optical fibre sensor probe (OFSP), whose sensing element is a bare, tapered and bent multi-mode optical fibre (BTBMOF).…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
