✦ Synopsis

This paper investigates up-conversion of a 54-Mb/s 802.11a WLAN signal in a radio-over-fiber (RoF) link. The frequency conversion is realized using either a DFB laser diode or an electro-optical modulator (EOM) (both biased in nonlinear regimes). Very low error-vector magnitude (EVM) measurements are reported at minimum of transmission of electro-optical modulator for a large 802.11a input power range, and an acceptable EVM degradation is obtained using the cost-effective LD mixing technique, but with a limited input power range.
