ZHR1000SD FTTH Seamohedi se phahameng sa Optical Optical
1 Tlhaloso ea sehlahisoa
ZHR1000SD FTTH seamohedi Optical e haholo-holo etselitsoeng ho marangrang CATV FTTH. Karolo ea eona ea mantlha ke tšebeliso e tlase ea motlakase, tlhahiso ea boemo ba kamehla ba AGC, Volume e nyane le ho ts'epahala ho phahameng. Ho amohela aluminium alloy shell, e nang le potoloho ea taolo ea AGC e hahiloeng kahare, sebopeho se kopaneng le phepelo ea motlakase e kantle ea modular e etsa hore ho hlongoa le ho etsa debugging ho be bonolo haholo. Ke sehlahisoa se setle sa ho aha marang-rang a FTTH CATV.
2. Sehlahisoa sa sehlahisoa
1. E amohela module ea GaAs joalo ka module ea RF e matlafatsang, mofuta oa ho amohela oa optical bakeng sa lets'oao la dijithale o ka fihlela -23dBm, le -15dBm bakeng sa lets'oao la analog.
2.Lekala la taolo ea AGC 0 ~ -10dBm, boemo ba tlhahiso bo boloka bo sa fetohe.
3. Moralo oa ts'ebeliso e tlase le ts'ebeliso e felletseng ≤2w, phepelo e phahameng e tšepahalang ea phepelo le potoloho ea tlhahlobo ea optical.
4. Palo ea tlhahiso e ka fetoloa kahare ho 0 -18dB, boemo ba tlhahiso ho feta 80dBuV.
5. Hlokomela 6VDC ~ 14VDC input koung fepa tsela ea phepelo matla
3. Tekanyetso ea tekheniki
