FILA 10 G Ethernet Interface Hardware complete (2 XFP + 2 SFP) Firmware Working Team (IRA, MPI, Metsahovi, SHAO) Firmaware on prototype now running in one board 2 x Gbps bidirectional (with std VLBI clock) 2 x Gbps bidirectional (with std VLBI clock) protocol UDP/IP with VDIF Output on 2 optical fibers and 2 copper (1 Gbps ea.) Developed additional interface Optical-CX4 (copper ) for MK5C

HAT-LAB Spin-off company approved by INAF on April 30 Agreement between HAT-Lab / INAF / MPI Bonn Additional bureaucracy still running, the spin-off not still operational until completion of all the procedures Requests can be addressed also now to the contact: Dr. Danilo Arena, Orders already pending for AuScope Production capability is about 4 systems / 4 months EVN production scheduling required
