Faster Communications on Existing Infrastructure

Facebook X LinkedIn Email
The 10-Gigabit Ethernet standard is encouraging faster data communications within local area networks, but intermodal dispersion effects limit the data rate on the standard optical fibre infrastructure in offices and factories. Two researchers from Universidad Politécnica de Valencia in Spain have combined low-linewidth distributed-feedback lasers with subcarrier multiplexing to send 10 simultaneous channels, each at 20 Gb/s, through 5 km of standard fibre network. The technique opens the possibility of radio-over-fibre transmission. These eye diagrams show the waveform and quality...Read full article
