Abstract

A single optical fibre may be used to simultaneously transmit a byte of data. The bits of the data byte are coded into separate colors and the separated color coded bits are transmitted through a composing prism to the optical fibre. The composite light signal is transmitted by the optical fibre to a decomposing prism where the composite signal is decomposed into its separate color coded bits. The received color coded bits are detected by detectors which provide an output in the original byte data form.

Optical Data-Transmission Multiplexer

A single optical fibre may be used to simultaneously transmit a byte of data. The bits of the data byte are coded into separate colors and the separated color coded bits are transmitted through a composing prism to the optical fibre. The composite light signal is transmitted by the optical fibre to a decomposing prism where the composite signal is decomposed into its separate color coded bits. The received color coded bits are detected by detectors which provide an output in the original byte data form.

The optical data transmitter is shown schematically in the figure. Binary bits are fed to optical emitters 1. Each emitter emits a unique color in response to a predetermined binary input. Each unique color is transmitted to composing prism
2. Each color is directed to the location on the face of the prism such that the beam from each color is bent in a manner that transmits each beam to a common point on the output face of prism 2. The multiplexed output from prism 2 is transmitted over a single optical fibre 3 to a decomposing prism 4 where the multiplexed output is decomposed into its original separate beams at the output face of prism 4. The output beams are transmitted to detectors 5 which reconvert the beam to binary bits.
