100Tbps Dense Wave Division Multiplexing [DWDM] can multiply the capacity of
existing fibre routes by sending 160 colours [300-500 planned] down a single strand of fibre. Each colour could sustain 40 Gb/s of data throughput and Lucent are experimenting with 160 Gb/s per colour. It is therefore entirely possible that the theoretical capacity of just one strand of fibre could be 100 Terabits. To put these capacities into perspective consider that a gigabit is equivalent to 1009 bits and a terabit to 1012 bits. A petabit, on the other hand, is 1015 bits of capacity. Larger capacities equate to exabit (1018 bits), zettabit (1021 bits) and yottabit (1024 bits).
