Abstract: A cable head end system and an operation method thereof for improving the signal quality are provided to reduce a channel up converter and a combiner by reducing cost of system and deterioration of the signal qualification. A cable head end system comprises a plurality of modulators(100), a multiple channel up converter(200), and an electric-optic converter(300). A modulator weighs the received signal with the cable broadcasting signal with the digital modulation. The multiple channel up converter up-converts signals which are digital modulated with a plurality of modulators. The multiple channel up converter unites the up-converted signals. The electric-optic converter converts the output signal of the multiple channel up converter into the optical signal.
