CABLE RANGER: Hybrid DOCSIS / HFC touchscreen analyzer

The CABLE RANGER is the latest introduction in our CATV analyzer product range. It is a hybrid analyser for DOCSIS and for HFC (optical) networks.

HFC networks use more and more fiber every time. CABLE RANGER includes an optical measurement input allowing field technicians not only to perform optical power measurements but also to do all the RFoG related RF measurements thanks to the built-in optical to RF converter. In this mode optical power measurement is shown together with the rest of the RF measurements. RFoG (Radiofrequency-over-Glass) is used more and more by CATV operators because it allows them to benefit from the advantages of fiber optics to compete with FTTH service providers.

CABLE RANGER is designed to be very easy to use yet offering all measurements required working with today’s complex hybrid fiber and coaxial networks. CABLE RANGER operation is easy and it is based in a touch screen graphical menu. A direct access ‘home’ button helps you return to a main menu page no matter what function were you using.
