Abstract
A light based communication system is provided including at least one phototransmitter which generates an optical signal which is detected by at least one photodetector that is encapsulated in potting material. The phototransmitter is optically coupled to the photodetector through the potting material. The photodetector transforms the optical signal into an electrical signal usable by electronic devices connected to the photodetector.
