A radio over multimode fiber (RoMMF) for short-range distribution of wireless signals with a very high performance to cost ratio is demonstrated. Thanks to the quality of today Fabry-Perot lasers, the adopted transmitter results from the conscious reuse of a solution initially conceived for single mode fiber transmission. The worst-case spurious free dynamic range of the proposed system exceeds 105 dBHz2/3 up to 525 m of OM2 multimode fiber. Experimental and theoretical results are reported showing that this scheme outperforms a RoMMF system employing either a distributed feed-back or a Fabry-Perot laser diode realized with recent-past technologies. With the proposed system, Long Term Evolution signal transmission is achieved with high quality in terms of Adjacent Channel Power Ratio and Error Vector Magnitude.

Abstract
A radio over multimode fiber (RoMMF) for short-range distribution of wireless signals with a very high performance to cost ratio is demonstrated. Thanks to the quality of today Fabry-Perot lasers, the adopted transmitter results from the conscious reuse of a solution initially conceived for single mode fiber transmission. The worst-case spurious free dynamic range of the proposed system exceeds 105 dBHz2/3 up to 525 m of OM2 multimode fiber. Experimental and theoretical results are reported showing that this scheme outperforms a RoMMF system employing either a distributed feed-back or a Fabry-Perot laser diode realized with recent-past technologies. With the proposed system, Long Term Evolution signal transmission is achieved with high quality in terms of Adjacent Channel Power Ratio and Error Vector Magnitude.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
