A system includes, in part, a multitude of RF receivers, a first optical modulator adapted to modulate an optical signal in accordance with a first data received by a first one of RF receivers to generate a first modulated signal, a second optical modulator adapted to modulate the optical signal in accordance with a second data received by a second RF receiver to generate a second modulated signal, and a first optical fiber adapted to carry the first and second modulated signals. The optical modulator may be a photodiode or a Mach-Zehnder modulator.
