Abstract

Abstract. Simultaneous transmission of 2.5-Gb/ s baseband and 5.8-GHz-band radio frequency ͑RF͒ signals on a single wavelength via a fiber link is successfully demonstrated using the optical diplexer and the newly designed novel baseband/RF mixed-signal multiplexer ͑MUX͒ with no mixer. The bit error rate ͑BER͒ Ͻ10 −12 of the baseband signal is maintained when the RF input power is less than −14 dBm after 10-km-long distance transmission. The maximum carrier-to-noise ratio ͑CNR͒ of the RF signal is measured as 23 dB with no additional amplifier. The measured insertion loss for the RF signal of the mixed-signal MUX is 1.2 dB at 5.8 GHz, and the isolations between the two bands are about 20 dB for the baseband and 30 dB for the RF band, respectively.
