Undersea cable sets new speed record
A new transatlantic undersea cable called Petal is set to transport data at a rate of one petabit per second across 7,000 kilometers between the United States and France. This marks the first time such a high data rate has been achieved in a commercial undersea network, according to Meta.Petal's speed explained
A petabit is equivalent to one million gigabits, or about 125 terabytes per second. At this rate, the cable could stream nearly 25,000 high-definition movies per second or allow 75% of the world's population to listen to music simultaneously. This doubles the capacity of current cables of similar length.Petal outperforms previous cables
Compared to Marea, the previous transatlantic link from Meta laid in 2018, Petal transports 5.5 times more data without increasing its diameter or electrical consumption. This significant improvement is due to the design of the glass fibers used in the cable.Innovative fiber design
Each glass strand in Petal has two cores, a first in commercial oceanic networks. This design allows for increased data transmission capacity without increasing the cable's size or power consumption, achieving unprecedented data density.
