Abstract
The present invention relates to an improved installation for conveying electrical signals carried by a first triaxial cable (2) to a second triaxial cable (6) and vice versa. It comprises: a first interface (3) between the first triaxial cable (2) and a fiber optic cable (4) and a second interface (5) between the fiber optic cable (4) and the second triaxial cable (6). A television camera (7) is connected to a remote camera control unit (1) via this installation. The first triaxial cable (2) connects the camera control unit (1) with the first interface (3). The first interface (3) comprises a first adapter converting electrical signals, conveyed by the first triaxial cable (2), to optical signals. The fiber optic cable (4) transmits optical signals to the second interface (5). The second interface (5) comprises a second adapter converting optical signals to electrical signals. The second triaxial cable (6) transmits the electrical signals to the television camera (7). A mirror image of the adapters allows transmitting electrical signals from the camera (7) to the camera control unit (1). The interfaces comprise A/D converters and D/A converters respectively adapted to convert anal…
