Optics in the surface, copper in the building–only to cope with a modern device that works in addition to the classic RF network with optical transmission–the optics makes the difference. For HF measurements and image processing, the Standard and Optical versions are identical. The Optical series also has an optical receiver and the CATV frequency range is extended to 1.214 MHz.
Currently, many large-scale CATV networks are switched to optical transmission. The advantage is a low signal attenuation and the potential freedom of the track. Despite different transmission methods in copper or otic networks, the measurements remain the same. In the measuring receiver, the demodulated optical signal is fed into the HF measuring branch. Therefore, all standard measurements can be performed.
