Abstract:
1. Installation for conveying electrical signals between a first triaxial cable connected to a camera control unit and a second triaxial cable connected to a camera, said installation comprising a first interface, configured to be connectable between the first triaxial cable and a fibre optic cable comprising one or more optical fibres, and a second interface, configured to be connectable between the fibre optic cable and the second triaxial cable, said first interface comprising a first and a fourth adapter, said second interface comprising a second and a third adapter, said first and said third adapters comprising said second and said fourth adapters comprising wherein said first adapter comprises one or more first digital filters, each connected between one of the analogue to digital converter circuits and one of the digital coding circuits, said first digital filters being configured to block or attenuate frequency ranges that correspond to frequency ranges of signals transmitted from the camera to the camera control unit and to pass frequency ranges that correspond to frequency ranges of signals transmitted from the camera control unit to the camera, or said second adapter comprises one or more second digital filters, each connected between one of the digital decoding circuits and one of the digital to analogue converter circuits, said second digital filters being configured to block or attenuate frequency ranges that correspond to frequency ranges of signals transmitted from the camera to the camera control unit and to pass frequency ranges that correspond to frequency ranges of signals transmitted from the camera control unit to the camera, or said third adapter comprises one or more third digital filters, each connected between one of the analogue to digital converter circuits and one of the digital coding circuits, said third digital filters being configured to block or attenuate frequency ranges that correspond to frequency ranges of signals transmitted from the camera control unit to the camera and to pass frequency ranges that correspond to frequency ranges of signals transmitted from the camera to the camera control unit, or said fourth adapter comprises one or more fourth digital filters, each connected between one of the digital decoding circuits and one of the digital to analogue converter circuits, said fourth digital filters being configured to block or attenuate frequency ranges that correspond to frequency ranges of signals transmitted from the camera control unit to the camera and to pass frequency ranges that correspond to frequency ranges of signals transmitted from the camera to the camera control unit.
