Optic fibre switch 1st to transfer data at 10 Gbps at -268ÂºC
A silicon-based optical fibre switch developed at a US-based laboratory is the first to transfer data up to 10 gigabits per second at near absolute zero temperatures. The device was tested at 25ÂºC, -173ÂºC and -268ÂºC and consumed 1000 times less power than commercially available electro-optical switches, hence, could be used for communications in extreme space conditions, said the developer.
