The backbone of experiments: Fiber optic cables & data storage

The backbone of experiments: Fiber optic cables & data storage

In addition to the sophisticated sensor network, a large network of fiber optic cables and ultimately data storage, forms the backbone of our research lab. Recently, another 1.2 petabytes of storage has been installed at the ETH Zurich.

Constantly, 800 MB of data per day are being sent from the acoustic emission sensors in the BedrettoLab to the servers in Zurich. On top of that, up to 1TB per day from the ongoing experiments, measured by sensors such as fiber optics interrogators, geophones, temperature, pressure and strain meters, are stored in the raw time series archive. This is a central access point for all data together with consistent timing information. For the researchers, this is the key for any type of synoptic interpretation, e.g. seismic event detection.
