On 3 December 2015 a first line with 18 Digital Optical Modules, each one containing a White Rabbit PTP Core - WRPC, was deployed successfully and communicated over 100 Km of fiber with the shore station.
This installation is 100 km into the sea off the coast of Italy at 3500 meter depth and must be the weirdest and harshest place to install WR nodes.
This is a first step in the installation of KM3NET, a European deep-sea research infrastructure hosting a neutrino telescope.
