Phys.org July 23, 2020 Researchers in Canada have developed a new technology that can translate data from microwaves to optical light. It works by introducing a strong interaction between microwave radiation and atomic gas. The microwaves are then modulated with an audio signal, encoding information into the microwave. This modulation is passed through the gas atoms, which are then probed with optical light to encode the signal into the light. The transfer of information from the microwave domain to the optical domain is the key result. The wavelengths of these two carrier signals differ by a factor of 50,000. It […]

New system transmits high-speed unrepeated signal over 520 kilometers
EurekAlert December 16, 2019 To make long-haul data transmission cheaper an international team of researchers (Russia, USA industry) developed transmission line with three sections, each consisting of fiber optic cables of two types connected in series. Remote optically pumped erbium amplifiers (ROPA) were installed at the points of junction between the sections. The systems amplify the signal along the link without the need for electrical power sources. They successfully transmitted a signal over 520 km (323 mi) at 200 Gbps. To avoid the attenuation of the signal, it was amplified initially upon transmission and then two more times remotely, along […]
