ROF -BPR letoto la module ea ho lemoha leseli le leka-lekaneng (photodetector e leka-lekaneng) e kopanya li-photodiode tse peli tse ts'oanang le amplifier ea Ultra-low lerata ea transimpedance, ka katleho e fokotsang lerata la laser le lerata le tloaelehileng la mokhoa, ho ntlafatsa tekanyo ea lerata ea tsamaiso, ho ba le mefuta e fapaneng ea karabelo ea spectral, Lerata le tlase, phaello e phahameng, e bonolo ho e sebelisa joalo-joalo, E sebelisoa haholo bakeng sa spectroscopy, ho lemoha heterodyne, optical delay measurement, optical coherence tomography le likarolo tse ling.
BPR letoto la 200M le 350M li-module tsa ho fumana tse phahameng tse nang le phaello e phahameng le litšoaneleho tse tlase tsa lerata, ka ts'ebetso e 'meli ea PIN ea karabelo ho fihlela tekanyo e phahameng ea ho hana mokhoa o tloaelehileng le amplitude e phahameng ea motlakase (~ 3.5V), mojule ona oa ho lemoha o ka fana ka mefuta e fapaneng ea ho fumana le ho kopanya tlhahiso ho latela litlhoko tsa bareki. E loketse haholo bakeng sa litsamaiso tsa ho lemoha tse momahaneng joalo ka radar ea moea ea Doppler e momahaneng.
