K'hamphani ea rona ea morao-rao e nang le lisebelisoa tse 'nè tsa CATV network optical receiver SR814ST, pre-amplifier e sebelisa li-GaAs MMIC tse feletseng,' me poso ea amplifier e sebelisa li-module tsa GaAs. Ka moralo o ntlafalitsoeng oa potoloho le lilemo tse 10 tsa boiphihlelo ba boqapi ba litsebi, sesebelisoa se fihletse matšoao a ts'ebetso e ntle haholo. Ntle le moo, taolo ea microprocessor le ponts'o ea paramethara ea dijithale li etsa hore ho rarolla bothata ba boenjiniere ho be bonolo haholo. Ke thepa e ka sehloohong e hlokahalang bakeng sa ho haha marang-rang a CATV.
Litšobotsi tsa Ts'ebetso
Motlakase oa rona o tsoetseng pele oa CATV network optical receiver SR814ST o amohela tšupu e fetolang photoelectric ea PIN e nang le likarabo tse phahameng, e ntlafatsa moralo oa potoloho le tlhahiso ea ts'ebetso ea SMT, 'me e hlokomela phetiso e bonolo le e sebetsang ea matšoao a photoelectric.
Li-chips tse inehetseng tsa RF li fana ka phokotso e nepahetseng, ha lisebelisoa tsa rona tsa amplifier tsa GaAs li fana ka phaello e phahameng le khopamiso e tlase. Sistimi e laoloa ke "single-chip" microcomputer (SCM), e nang le likarolo tsa ponts'o ea LCD, ts'ebetso e bonolo le e hlakileng, le ts'ebetso e tsitsitseng.
Sistimi ea AGC e etsa bonnete ba hore boemo ba tlhahiso bo lula bo sa fetohe ho feta mefuta ea matla a mahlo a -9 ho ea ho +2 dBm ka tšitiso e fokolang ho tsoa ho CTB le CSO. Tsamaiso e boetse e kenyelletsa sebopeho sa puisano ea data e boloketsoeng, e ka kopanngoang le mofuta oa II oa tsamaiso ea tsamaiso ea marang-rang 'me e kopantsoe le tsamaiso ea tsamaiso ea marang-rang.Mekhahlelo eohle ea tekheniki e lekantsoe ho latela GY/T 194-2003, tlas'a maemo a tloaelehileng a teko.
