SR812ST-R ke seamoheli sa rona sa morao-rao sa maemo a holimo a mabeli sa CATV network optical receiver. Pre-amplifier e nka MMIC e felletseng ea GaAs, post-amplifier e amohela mojule oa GaAs. Moralo o ntlafalitsoeng oa potoloho hammoho le boiphihlelo ba meralo ea rona ea lilemo tse 15, e etsa hore lisebelisoa li fihlelle li-index tse ntle tsa ts'ebetso. Taolo ea Microprocessor, pontšo ea dijithale ea li-parameter, ho lokisa bothata ba boenjiniere ho bonolo haholo. Ke thepa ea mantlha ea ho aha marang-rang a CATV.
Litšobotsi tsa Ts'ebetso
- Karabelo e phahameng ea PIN ea phetoho ea lifoto tsa motlakase.
- Moralo o ntlafalitsoeng oa potoloho, tlhahiso ea ts'ebetso ea SMT, le tsela ea mats'oao e ntlafalitsoeng e etsa hore phetiso ea lets'oao la photoelectric e be bonolo haholoanyane.
- Chip e khethehileng ea RF attenuation, e nang le RF attenuation e ntle le equilibrium linear, ho nepahala ho phahameng.
- Sesebelisoa sa amplifier sa GaAs, tlhahiso ea matla a habeli, e nang le phaello e phahameng le khopamiso e tlase.
- Sesebelisoa sa taolo ea Single Chip Microcomputer (SCM) se sebetsang, LCD e bonts'a liparamente, bonolo le ts'ebetso e hlakileng, le ts'ebetso e tsitsitseng.
- Ts'ebetso e ntle haholo ea AGC, ha matla a optical a kentsoeng a le －9～＋2dBm, boemo ba tlhahiso bo lula bo sa fetohe, 'me CTB le CSO ha e le hantle ha li fetohe.
- Sehokelo sa puisano sa data se bolokiloeng, se ka hokahana le sehlopha sa Ⅱ se arabelang taolo ea marang-rang, le ho fihlella sistimi ea taolo ea marang-rang.
- Ho khutlisa ho ka khetha mokhoa oa ho phatloha ho fokotsa haholo khokahano ea lerata le ho fokotsa nomoro ea moamoheli.
