Stable radio-frequency transfer over optical fiber by phase-conjugate frequency mixing.
We demonstrate long-distance (≥100-km) synchronization of the phase of a radio-frequency reference over an optical-fiber network without needing to actively stabilize the optical path length. Frequency mixing is used to achieve passive phase-conjugate cancellation of fiber-length fluctuations, ensuring that the phase difference between the reference and synchronized oscillators is independent o...

متن کاملCompensation of dispersion-induced power fading for highly linear radio-over-fiber link using carrier phase-shifted double sideband modulation.
A carrier phase-shifted (CPS) double sideband (DSB) modulation technique in radio-over-fiber (RoF) system is proposed and experimentally demonstrated. By tuning the biases in a single-drive dual parallel Mach-Zehnder modulator (SD-DPMZM), the optical carrier in the DSB spectrum acquires additional phase shift. The transmittance response of a dispersive RoF link is thus being controlled and shif...
متن کاملPhase-modulated radio over fiber multimode links.
We present the first experimental demonstration of a phase-modulated MMF link implementing high-frequency digital transmission in a cost-effective solution based on direct detection. Successful subcarrier transmission of QPSK, 16-QAM and 64-QAM data channels for bit rates up to 120 Mb/s through a 5 km MMF link is achieved over the microwave region comprised between 6 and 20 GHz. The overall cap...
متن کاملPerformance Comparison of Analog and Digital Radio Over Fiber Link
In order to meet the ever increasing demand for larger transmission bandwidth, Wireless network based on radio-over-fiber technologies is a very beneficial solution. Various disadvantages of Analog Radio over Fiber link such as non-linearity, chromatic Dispersion can be mitigated by use of Digital Radio over Fiber link. A digitized RF-over-Fiber transmission scheme based on Bandpass Sampling th...
