July 5, 2018, 15:49 Washigton, Jul. 5 (Prensa Latina) An international team has designed an amplifier that can multiply nearly six times the conventional range of an optical fiber transmission up to 39, to reach four thousand kilometers, publishes today the magazine Nature Communications.
With the replacement of conventional devices by optical amplifiers sensitive to the ultra-low noise phase, the researchers demonstrated that it is possible to reduce the impact of noise accumulation and distortion of the signal of nonlinear effects in the transmission fiber
Both are the main limitations of range and capacity in transmission links. The current optical fiber transmission
Although several engineering challenges remain before these amplifiers can be implemented commercially, for the first time the results show the great benefits of their use in optical communication, said Peter Andrekson, Head of
These amplifiers can provide improved range over conventional approaches, and also increase the performance of future fiber optic communication systems.
Applications can also be found in quantum computing, as well as in spectroscopy (study of the interaction between electromagnetic radiation and matter, with absorption or emission of radiant energy), which could benefit from a very low noise amplification, adds Professor Andrekson.
