The optical QUATRO converter converts the signal 950 - 5450 MHz coming from the LNB via a fiber optic cable into a standard satellite signal in the range 950 - 2150 MHz. The Quatro converter has 4 outputs for the satellite levels vertical and horizontal low, vertical and horizontal high as well as a terrestrial output, suitable for connecting multiswitches and headends. If these devices cannot provide a power supply, the OMS12NT power supply is required.
