The intermediate frequency was 1.5 GHz. 8.4 Mbit/s digital signals were transmitted over 280 m of single-polarisation fibre by a subcarrier modulated baseband method.endigital communication systemsoptical fibresoptical linkssingle-channel single-polarisation all-fibre-optic transmission system830 nm wavelengthtransmitter laserheterodyne receiverlocal lasermonomode fibreapd mixersubcarrier modulated baseband method621384journal article
