In this live demonstration, we will show the operation of a high speed transcutaneous optical telemetric link, through a piece of pork skin as the transmission medium. In all experiments, a PRBS (Pseudorandom Binary Sequence) generated by a linear-feedback shift register (LFSR) implemented on an Altera FPGA will be used as test signal. The optical transmitter converts the electrical signal into an optical one which is then received by a photodiode, before it is amplified and digitized by means of a TIA, a limiting amplifier and a CDR (clock and data recovery circuit).
