Exabit Transmission Speeds May Be Possible
adeelarshad82 writes "Scientists at UC Berkeley were able to shrink a graphene optical modulator down to 25 square microns in size (small enough to include in silicon circuitry) and were able to modulate it at a speed of 1GHz. The researchers say that modulation speeds of up to 500GHz are theoretically possible. According to the research, due to the high modulation speeds, a graphene modulator can transmit a huge amount of data using spectral bandwidth that conventional modulators can only dream of. Professor Xiang Zhang, in an attempt to boil his group's new findings into consumer-speak, puts it this way: 'If graphene modulators can actually operate at 500GHz, we could soon see networks that are capable of petabit or exabit transmission speeds, rather than megabits and gigabits.'"
