Radio and Power over Fiber System for 4K/8K Satellite Antenna

抄録

In the new 4K/8K satellite broadcasting, the maximum intermediate frequency (IF) is proposed to be changed from 2071 MHz to 3224 MHz. The coaxial cable has been widely used for IF signal transmission, but the attenuation is significant with a high signal loss when a high-frequency signal is transmitted. With the increasing number of 4K/8K channels and the development of broadcasting technology, the frequency used for the IF signal will keep increasing. Therefore, the coaxial cable may not meet the future ultra-high-definition satellite broadcasting requirements anymore. Compared to the all-electrical signal transmission, the Radio-over-Fiber (RoF) system can achieve signal transmission with lower loss and reduce noise sensitivity by transmitting the signal through an optical fiber. In this work, we propose a system that uses the RoF technology to reduce the signal loss during high-frequency transmission while adopting the Power-over-Fiber (PoF) technology to generate electric power for Low-Noise Block (LNB) and RoF unit on the antenna side. A method that combines the RoF technology and PoF technology into one Double-clad Fiber is also reported. With the comparison between the signal transmitted through an RoF system and that through a coaxial cable, it can be clearly shown that the advantage of the RoF technology in the signal loss performance. The experimental results of signal transfer demonstrate that by using the RoF technology, the average amplitude of the effective signal containing TV channels increases by 8.89 dB in the range of 2224-3224 MHz, while the average amplitude increases by 5.7 dB for the effective signal in the range of 1032-2071 MHz.
