Anritsu's optical analyser picked by NAOJ
Anritsu is pleased to announce that the National Astronomical Observatory of Japan (NAOJ) has selected the Anritsu 400G Tester and Optical Spectrum Analyzer MS9740B for the evaluation of a new data transmission system (DTS) for the Atacama Large Millimeter/submillimeter Array (ALMA) located in Chile
The Network Master Pro MT1040A of the 400G Tester was used to evaluate the DTS communication function with 1.6Tbps data transmission.
NAOJ is deeply involved in the operation of ALMA, which is overseen by a global partnership of 22 countries and territories, including Japan, and is responsible for the improvement of the performance of the radio telescope to take it into the 2030s (Wideband Sensitivity Upgrade (WSU)).
NAOJ is cooperating with the National Radio Astronomy Observatory (NRAO) in the USA to facilitate the communication of large amounts of observational data between the antennas (radio telescope) and the correlator (supercomputer) using the 400ZR * standard and, currently, is considering high-speed communication at 1.6 Tbps.
The MT1040A, which is compatible with the 400ZR standard, was selected for DTS evaluation; the MT1040A has a feature that displays the physical layer measurement results at one-second intervals, allowing the detailed evaluation of the quality of the transmission of large amounts of astronomical data. In addition, the MS9740B has been selected to monitor the optical wavelength of the transmission signal during DTS evaluations.
