Hey guys! Just found on ebay: http://cgi.ebay.com/Lot-of-5-80MHz-Si-PIN-Photo-Diode-for-Laser-Diode-Sense_W0QQitemZ270191338452QQihZ017QQcategoryZ4660QQcmdZViewItem Anyone already made some experiences with it? Seems to be suitable for 100Mbit receiver. (31.25MHz is much lower than the 80MHz) bye Martin
