Luminescent solar concentrators (LSCs) have recently emerged as a promising receiver technology in free-space optical communications due to their inherent ability to collect light from a wide
A communications system component that multiplexes a number of separate incoming fiber optic communications channels.
Fluorophore doped plastic optical fibers can be used to create optical concentrators in receivers for visible light communications, that also act as wide
In telecommunications, the term concentrator has the following meanings: • In data transmission, a functional unit that permits a common path to handle more data sources than there are channels currently available within the path. A concentrator usually provides communication capability between many low-speed, usually asynchronous channels and one or more high-speed, usually synchronous channels. Usually different speeds, codes, and protocols can be accommodated
An Ethernet hub or concentrator is a device for connecting multiple twisted pair or fibre optic Ethernet devices together, making them act as a single segment. It works at the physical layer of the OSI
