Abstract
Apparatus for providing an interface between a triaxial cable and a fiber optic cable for transmission of television signals between a camera and a camera control unit includes first and second converter circuits coupled between the triaxial cable and the fiber optic cable. The first converter circuit converts a first electrical signal received from the triaxial cable to an optical output signal. The second converter circuit converts an optical input signal received from the fiber optic cable to a second electrical signal. The first and second electrical signals each include a plurality of television signals in a frequency division multiplex format. The first converter circuit includes a plurality of bandpass filters coupled in parallel to receive the first electrical signal each of which passes one of the first television signals. The second converter circuit includes a plurality of bandpass filters coupled in parallel to receive the second electrical signal, each of which passes one of the second television signals. The converter circuits provide automatic gain control of the bandpass filtered television signals to automatically adjust for varying lengths of triaxial and fiber op…
