Massive Bandwidth to Come From Wavelength Division Multiplexing and Coherent Communications

I was just reading an article on the FASTER project, which is a submarine cable project that will deliver an initial information capacity of 60 Terabits Per Second (Tbps) between the US and Asia. This is substantially more than the 4 Tbps we typically see today in these systems (example). It does this by extensive use of Wavelength-Division Multiplexing (WDM), with each wavelength carrying 100 Gigabits per second (Gbps) over a six-pair cable. Continue reading
