Simplified radio-over-fiber transport systems with a low-cost multiband light source.

摘要: In this Letter, low-cost radio-over-fiber (ROF) transport systems are proposed and experimentally demonstrated. By utilizing a laser diode (LD) local oscillator (LO) to generate coherent multiband optical carriers, as well self-composed wavelength selector separate every two carriers for different ROF systems, no any other dedicated LD or electrical frequency upconverting circuit/process is needed in the central station (CS). Compared with current required numbers of LDs, LOs, mixers CS significantly reduced. Reducing number components not only can simplify network structure but also reduce volume complexity relative logistics. To demonstrate practice clear eye diagrams error-free transmission performance presented.
