一,Molao-motheo oa photoreceptor
Thee amohelang mahloke karolo ea bohlokoa ea tsamaiso ea optical fiber puisano. Molao-motheo oa eona oa motheo ke ho fetola lipontšo tsa optical ka lipontšo tsa motlakase. Likarolo tse ka sehloohong tsa mochine o amohelang mahlo li kenyelletsa photodetector, preamplifier le postamplifier. Ha lets'oao la optical le fetisetsoa ho photodetector ka fiber optical, photodetector e fetola letšoao la optical ka letšoao la motlakase, ebe letšoao lea matlafatsoa le ho hloekisoa ka preamplifier, 'me qetellong le sebetsoa le ho fetisoa ka poso.
二、Mosebetsi oa photoreceptor
1. Phetoho ea matšoao a optical ho mats'oao a motlakase:Mosebetsi oa mantlha oa moamoheli oa optical ke ho fetolela matšoao a optical a fetisitsoeng hore e be mats'oao a motlakase ho nolofatsa ts'ebetso le phetisetso e latelang. Sena se etsoa ho sebelisoa li-photodetectors, tse lemohang mats'oao a leseli a fokolang ebe li a fetola mats'oao a motlakase.
2. Matlafatso ea lets'oao:Kaha matla a lets'oao la optical a tla fokola butle-butle nakong ea mokhoa oa phetisetso ea optical fiber, matla a pontšo ea optical a ka 'na a fokola haholo ha a fihla ho optical receiver. Preamplifier ka har'a seamoheli sa optical se ka holisa matšoao ana a fokolang a motlakase e le hore a ka sebetsoa hantle le ho fetisoa.
3. Sefe ea lets'oao:Nakong ea ts'ebetso ea phetisetso ea fiber optical, ho ka hlahisoa lerata le litšitiso tse fapaneng, tse tla ama boleng ba lets'oao. Preamplifier ho seamoheli sa optical hangata se na le sefe ho tlosa lerata lena le tšitiso le ho ntlafatsa boleng ba lets'oao.
4. Ts'ebetso ea mats'oao:Post-amplifier e ka tsoela pele ho sebetsana le lets'oao la motlakase, joalo ka decoding, demodulation, joalo-joalo, e le hore e ka khutlisoa ho lets'oao la pele la dijithale kapa la analog. Ho phaella moo, ka post-amplifier, letšoao la motlakase le ka boela la fetoloa le ho ntlafatsoa, joalo ka ho lokisa amplitude, frequency le likarolo tse ling tsa pontšo, e le hore e ka finyella litlhoko tsa mekhoa ea puisano e latelang.
5. Lipontšo tsa motlakase tse tsoang:Lipontšo tsa motlakase tse sebelitsoeng li ka hlahisoa ho lisebelisoa tse ling kapa litsamaiso ho fihlela phetiso ea tlhahisoleseling le ho arolelana. Ka mohlala, tsamaisong ea puisano ea optical fiber, matšoao a motlakase a sebelisoang ke mochine oa optical a ka fetisetsoa lik'homphieutha, li-switches kapa lisebelisoa tse ling tsa puisano.
