Hi all,
I am to be working on my senior design project this year and we chose to make a LIFI application. My main goal is to transmit information from an RJ45 ethernet connection into a modulated LED which can be bought off the shelf. Of course in order to browse the internet both systems need a TX/RX on both ends but for now we are going to just make the TX before anything else. In theory our system should only accept the data from any ethernet port which should be some typeManchesterster coding at 10,100,1000 Mb/s and then transform that into a signal which can modulate an LED. As a reference I was looking at this paper A low-cost man-portable free-space optics communication device for Ethernet applications . They used a ML6652RDK which took their ethernet signal and created a modulated signal for a laser diode, the problem is the company isnt in business anymore and I have been trying to find a replacement for this module. I was looking at the ONET1141L but I'm not quite sure that is going to get the job done. If anyone had some information they could share which can help me understand how to accomplish this or design my own components I would greatly appreciate it.
