I have some possibly useful information for people on optical communication over of plastic fiber. I spent a few days studying this. The POF org has a number of links and the names of companies that can help in finding things http://pofto.com/ Toshiba Optical http://www.toshiba.com/taec/cgi-bin/display.cgi?table=Family&FamilyID=19 has a nice list of various modules and available data sheets. Sharp http://www.sharpsma.com/sma/products/Optoelectronics.htm has no data sheets available online, however they do have a list of parts, just not what they fit (IE no data sheets) :/ Firecoms http://www.firecomms.com/ has a number of high speed individual components that can be used to make a high speed optical system. They have ROS and TOS in visible light and infrared. Green and Red are available for transmitters. Some are good to 250mbps. POFeska http://www.pofeska.com/pofeskae/pofeskae.htm is mitsubishi's optical fiber manufacturer. Lots of good information to look at there for the right type of cable to select. The interesting thing is the selection of integrated solutions is very narrow. Audio links appear to use the lower speed links from 5 to 15mbps NRZ these come with integrated packages for data in and out but as it seems are quite limited in bandwidth. Optical 1394 connection systems exist (I wanted to avoid using something like 1394 myself), they range from 50 to 250 and soon 500 mbps. Sharpe and Toshiba appear to be the primary manufacturers of integrated link systmes (and there speed goes up to 15mbps Toshiba and 25mbps Sharp). I thought people might want to have some ideas to find out what is what :) ===== Stephen R.
