  • Apparatus for communicating a plurality of antenna signals at different optical wavelengths
    Patent number: 9184842
    Abstract: A remote radio unit is disclosed that includes antenna interfaces, RF receivers, and a digital-to-optical converter. The antenna interfaces each receive an antenna signal from a different antenna. The RF receivers downconvert the antenna signals to baseband signals, and convert the baseband signals to digital streams of user data. The digital-to-optical converter converts each of the digital streams of user data to optical signals having different optical wavelengths for output to an optical fiber for communication to a radio equipment control unit. Related radio base stations and network control points are disclosed.
