Modems used to give out 57.6 Kbps with a bang. Today, the speeds are prohibitive even for downloading heavy files!
Access to the Internet is both wired and wireless. Most often at home or in the office we use the "wired" Internet, while when we go outside the premises, we are surrounded by all kinds of open and closed Wi-Fi networks, as well as cellular networks of telecom operators. The development of the latter has reached the 5th generation, while the wired Internet, thanks to Nokia Bell Labs specialists, has set a world record of transmission speed - 1.52 Tbps!
This achievement will enable the creation of faster 5G networks. Nokia Bell Labs has announced that its researchers have set a world record for single-carrier transmission speed of 1.52 Tbps over an 80 km stretch of standard single-mode fiber. This is four times the rate of the best commercially available solutions currently on the market, approximately 400 Gbps. The following comparison gives a clear idea of the record speed: it is equivalent to simultaneous streaming transmission 1.5 million YouTube videos.
"This world record will further strengthen Nokia's ability to develop networks for the 5G era to meet the ever-increasing data, capacity and latency requirements for the Industrial Internet of Things and consumer applications."

The record was set with a new converter that can generate signals with a 128 Gbaud symbol rate and an individual symbol information rate of more than 6.0 bits per symbol and polarization value.
At the same time, a world record has been set for data rates for direct modulated lasers (DMLs), which are crucial for low-cost, high-speed applications such as data center links. The record value exceeds 400 Gbit/s for links up to 15 km long.
