Paper Abstract

An optical transmitter system-on-packaging (TxSoP) with an electro-absorption modulator (EAM) was developed for 60-GHz band rf with radio-over-fiber (rf/RoF) uplink. An analysis to develop the TxSoP with a small noise figure was performed so that the noise figure of the modified TxSoP decreased by 15 dB. The rf/RoF uplink with the modified TxSoP was established, and the error vector magnitude (EVM) and the signal-to-noise ratio (SNR) of the link were measured between 2.2% and 3.2% and between 26 dB and 29 dB from 140 MHz to 800 MHz, respectively. Digital CATV signals corresponding to 86 channels were transmitted through the link, and total throughput of the link was 2.6 Gbps.
