Optical Re-Modulation in DWDM Radio-Over-Fiber Network |
摘要 |
An apparatus includes multiple signal paths for optically converting an optical signal to multiples of the optical signal at different respective carrier frequencies for reducing interference between wireless transmissions of the multiples of the optical signal. Preferably, the converting includes a first modulator for modulating the optical signal into a first optical carrier and an initial first-order sideband signal with a frequency spacing twice that of the first optical carrier and a first interleaver for separating the first optical carrier and the initial first-order sideband signal. The converting also includes a second phase modulator for modulating the first optical carrier into a second optical carrier and a second first-order sideband signal with a frequency spacing twice that of the second optical carrier.
