In Deutsche Telekom set a record for the speed of stable data transmission at 400 Gbit / s

At the same time, the company's specialists worked not with a new type of channel, but with ordinary fiber. Having received such a result, data transmission with a speed of 400 Gbit / s, the German company automatically set a record for data transfer speed (per fiber channel). The project was named OSIRIS (Optically Supported IP Router Interfaces). Previously, the record data transfer rate over a single fiber channel was 186 Gbps.
/ sec. This result was obtained by a team of independent experts.

The record was set on the channel with a large length. So, the data was transferred from Berlin to Hannover and back, which is approximately 734 kilometers of the way. At the same time, data transfer was quite stable up to the indicated 400 Gbit / s. Experts tried to raise the speed up to 512 Gbit / s, but after the barrier of 400 Gbit / s, the transfer was already unstable, so this result was recognized as a record. According to the company's employees, the theoretical speed when using an experienced technology can reach a “ceiling” of 24.6 Tbit / s.

As for the results of Deutsche Telekom, the telecom operator is going to use its groundwork for the practical implementation of this technology. According to experts of the company, this speed can be normal in a short time. True, the original channels with increased bandwidth will be transferred to customers who need such performance. It is unlikely that it will be customers-individuals. Most likely, Deutsche Telekom will initially cooperate with large companies from the IT sector, and then implement the technology for everyone else.

The project was developed jointly with a company such as Alcatel-Lucent. Both companies say that to achieve the above data rates, the replacement of communication lines is not needed. Only a change of terminal equipment is needed. But when the equipment will be replaced and the capacity of the channels from Deutsche Telekom will increase, is still unknown.
