Overcoming Modal Bandwidth Limitation in Radio-over-Multimode Fiber Links

Employing the optical frequency multiplication method, the theoretical modal bandwidth limitation of multimode fiber (MMF) can be overcome in radio-over-fiber links. The principle is analyzed theoretically and supported experimentally by generation and transmission of microwave carriers up to 40 GHz...

Zusammenfassung:Employing the optical frequency multiplication method, the theoretical modal bandwidth limitation of multimode fiber (MMF) can be overcome in radio-over-fiber links. The principle is analyzed theoretically and supported experimentally by generation and transmission of microwave carriers up to 40 GHz and 16- and 64-level quadrature-amplitude-modulated (QAM) radio signals in the 24- to 30-GHz band over 4.4-km MMF link
