The FibreIRS GTU converts optical power to RF power (4 satellite bands and FM,DAB,DTT ). All units have built in AGC which allows a wide dynamic range of optical powers without affecting output power and quality. Two LED indicators allow the user to monitor the status of the unit.
Quad GTU is for use directly with a STB/faceplate.
Can be powered via the satellite outputs and used with either the Optical LNB or the ODU32.
