Small ONU module for FM converted multichannel video signal transmission systems

Summary form only given. FM converted multichannel video signal transmission systems have a lot of advantages such as large optical power budget and robustness against optical reflection and chromatic dispersion. These systems are thus attractive for video signal distribution in access networks, especially for fiber-to-the-home (FTTH). The optical network unit (ONU) must offer low cost, compactness, and low power consumption if the systems are to become practical. To this aim, we have proposed a small ONU module consisting of a superlattice APD and a fully integrated 1-chip Si-IC operating as FM signal demodulator and RF output FDM signal amplifier.
