Nokia Bell Labs and Deutsche Telekom collaborate to achieve 1Tbps fiber transmission speeds

Nokia Bell Labs, Deutsche Telekom team T-Labs and the Technical University of Munich have joined forces to achieve optical fiber transmission speeds
of 1Tbps.

According to Nokia Bell Labs, the breakthrough will enable telecom operators and enterprises to further improve the distance and capacity
of high-speed data transmission in optical metro networks and core networks.

The demonstration shows that optical networks can achieve optimal performance
when adjustable transmission rates dynamically adapt to channel conditions and traffic requirements.

The European Routing Technology (SASER) project as a security guarantee achieved a transmission speed
of 1 TB through the test of Deutsche Telekom's optical fiber network.

Probabilistic Constellation Shaping (PCS) provides the flexibility and performance to bring optical network operations closer to the Shannon limit to meet data needs
.

Marcus Weldon, Chief Technology Officer at Nokia, said: "Probabilistic constellation formation brings fiber network operations closer to the limit, supports large numbers of data center interconnects, and provides the flexibility and performance needed for modern networks in the data age, thereby providing great convenience
to service providers and enterprises.
