Radio over dwdm transport systems for PHS/VICS/ETC/SB applications FBG

A radio over dense-wavelength-division-multiplexing (DWDM) transport system for personal handy system (PHS)/vehicle information and communication system (VICS)/electronic toll collection (ETC)/satellite broadcasting (SB) applications was proposed and demonstrated. Improved performance of bit error rate (BER) over a-100 km of large effective area fiber (LEAF) was obtained. Signal qualities meet the PHS demand with a data signal of 1.9 GHz/10 Mbps, VICS demand with a data signal of 2.5 GHz/12 Mbps, ETC demand with a data signal of 5.8 GHz/20 Mbps, and SB demand with a data signal of 12 GHz/25 Mbps.
