60 GHz band RF/RoF Link characteristics of enhanced optical transmitter SoP module

An optical transmitter system-on-packaging (SoP) with an electro-absorption modulator (EAM) was developed for 60 GHz band radio-over-fiber (RoF) uplink. An analysis to develop the SoP module with small noise figure was performed, so that the noise figure of the RF/RoF link with the SoP module was measured 8.445 dB at 500 MHz. The SNR and EVM of the link were measured and the corresponding BER was estimated. If FEC adopted, the link was proved to be used in conveying the data communications for a cable television.
