Researchers from Siemens Networks demonstrated the ability to transmit data at 10 Gbps error-free over a passive optical access network -- this is four times faster than current GPON technology. The upstream capacity was rated at 2.5 Gbps and the number of subscriber lines per splitter was expanded to 512. Siemens also achieved a 100 kilometer distance between hub and subscribers -- the so-called last mile. Current PONs typically support subscribers...
