Kakaretso ea Sehlahisoa
OR-1310 outdoor laser transmitter (Relay station) ke sehlahisoa se hlahang sa Softel. Ka lilemo tse bokelletsoeng tsa boenjineri ba marang-rang a HFC le boiphihlelo ba ntlafatso ea lisebelisoa, tse ntlafalitsoeng ka ho khetheha bakeng sa 1310nm outdoor optical emission kapa transmission ea optical relay. Tsoelo-pele e atlehileng ea sehlahisoa sena e fana ka tharollo ea moruo le e sebetsang bakeng sa 1310nm outdoor optical emission kapa optical relay transmission ho CATV engineering practice.
Litšobotsi tsa Ts'ebetso
- Karolo ea phetoho ea photoelectric e amohela mochini oa morao-rao o tsoang kantle ho naha o bitsoang optoelectronic integrated receiver module;
- Karolo ea Optical emission e amohela mofuta oa morao-rao oa DFB laser e sebetsang hantle haholo; e fana ka phetiso ea matšoao a boleng bo holimo bakeng sa marang-rang a CATV.
- Haha ka har'a amplifier ea RF le potoloho ea taolo ho netefatsa lerata le tlase le index ea intermodulation; 'me e ka hlahisa mekhoa e' meli ea lets'oao la boleng bo holimo la RF ho koahela basebelisi ba lehae.
- Potoloho e nepahetseng le e ts'eptjoang ea matla a optical e tsitsisa potoloho le mochini o futhumatsang oa motlakase o hahelletsoeng ka har'a matla a phahameng, e nolofalletsa phapang ea mocheso o teng ho fihla ho ± 40 ° C, ho netefatsa ts'ebetso e ntle ea mochini le ts'ebetso e tsitsitseng ea nako e telele ea laser. .
- Pontšo ea boemo ba LCD, likarolo tse kholo tsa ho sebetsa li hlakile ha u habanya feela.
- Sebopeho se sebetsang hantle le se utloahalang, ho kenya le ho lokisa liphoso, ts'ebetso e tsitsitseng le e ka tšeptjoang.
- Thepa e ka sebetsa ka mokhoa o tsitsitseng ka ntle tlas'a maemo a mabe a tikoloho, ka lebaka la mokotla o moholo oa aluminiamo o sa keneleng metsi, matla a ho fetola matla a matla, le mokhoa o tiileng oa tšireletso ea lehalima.
