In each household, the down-converted signal is then converted back to the original frequency at the receiver for viewing on an 8K television. This approach makes it possible to receive 8K broadcasts using existing satellite reception equipment, greatly reducing the labor and cost of refurbishment. Reception Method Using a Receiving System With POF Cable POFs5,6 are used in data centers and elsewhere. We have developed equipment for receiving satellite broadcasting using POFs. Quartz glass singlemode fibers (SMFs) are often used as optical fibers in many broadcasting/communication installations, such as fiber to the home (FTTH). Although the signal attenuation and other characteristics of POFs are inferior to those of glass-based SMFs, their high flexibility and tolerance to shaft misalignment mean that POFs are unaffected by problems common to quartz glass SMFs, such as workability, safety, and bend resistance. In Japan, 64% of apartment blocks consist of smalland medium-sized buildings of five stories or less. In this case, since the transmission distance from the antenna to the television is about 100 m or less, signal attenuation is within an allowable range when using a POF receiving system. Moreover, since POFs are thin and have excellent flexibility compared with conventional coaxial cables, flexible installation is possible. A system using a POF connection is shown in Fig. 12. In an apartment block that is difficult to renovate, an optical transmitter and a receiver are installed alongside the existing receiving equipment, and a new POF cable is installed in the gaps in the piping by exposed wiring. This makes it possible to support 4K/8K satellite E/O POF ONU 4K8K TV 4K/8K TV E/O POF Coaxial cable 10 20 30 plastic optical fiber ONU Reception system EXTERNAL
