Kakaretso e Khutšoanyane
SR4020AW Optical receiver ke seamoheli sa lapeng se nang le phihlello ea fiber e le sepheo sa sona sa mantlha. E loketse liteishene tsa phihlello tsa bareki ba marang-rang ba FTTH (fiber to the home), e nolofalletsang matšoao a analoge kapa a dijithale ho kena ka tlung. Mochine o sebelisa li-photodetectors tsa matla a tlaase, li-GaAs, le theknoloji ea optical AGC ho finyella litlhoko tsa kamohelo ea CATV ea fiber-to-the-hae. Sesebelisoa sena se ka eketsa WDM mme sa fihlella papali e meraro.
Litšobotsi tsa Ts'ebetso
- khetla ea boemo bo phahameng ba aluminium e nang le mocheso o motle oa ho senya.
- Seteishene sa RF se felletseng sa GaAs lerata le tlase la amplifier. Letšoao la digital le khotsofatsa kamohelo ea -18dBm bonyane le kamohelo ea -10dBm ea letšoao la analog bonyane.
- Ka optic input AGC (AGC mofuta o hlophisitsoeng).
- Moralo o nang le matla a tlase, o sebelisa phepelo ea matla a phahameng a ho fetola matla ho netefatsa ts'epo e phahameng le botsitso bo phahameng ba phepelo ea motlakase. Kakaretso ea tšebeliso ea matla e ka tlase ho 1W, e nang le potoloho ea leseli.
- Lisebelisoa tse sireletsang lehalima tse nang le mekhahlelo e mengata (TVS transient suppression diode), le lisebelisoa tsa tšireletso ea lehalima li tiile ho netefatsa ts'ebetso e sireletsehileng ea lisebelisoa.
- WDM e hahelletsoeng ka hare e khona ho fumana lisebelisoa tsa khokahanyo ea marang-rang a le mong (1490/1310/1550nm).
- E hahelletsoeng ka har'a isolator ea optical, ho kenya letsoho ho fihlela ho itšehla thajana ho 1490/1310nm.
- Phaello e hlahisoang e ka fetoloa ka letsoho (0~18dB) mme boemo ba tlhahiso ke> 80dBuV.
- SC/APC kapa FC/APC kapa lihokelo tsa optical tsa tloaelo, metric kapa meemphera ea RF interface.
- E khona ho hlokomela mokhoa oa phepelo ea motlakase oa phepelo e tsoang.
- Liphetho tse le 'ngoe kapa tse peli lia ikhethela
Keletso le Tlhokomeliso:
Maemo a teko: 59 PAL-D matshwao a kanale a analoge a seteishene sa thelevishene ho 550 MHz frequency range, ho tloha 550 MHz ho ya ho 862 MHz, tlasa maemo a itseng a tahlehelo ya sehokelo.
Letšoao la ho feto-fetoha ha dijithale le fetisoa ka har'a sekhahla sa sekhahla, boemo ba lets'oao la ho feto-fetoha ha dijithale (ka har'a bandwidth ea 8 MHz) ke 10 dB ka tlase ho boemo ba sephethephethe sa lets'oao la analog, 'me matla a optical receiver optical ke 0dBm, a lekanya C. /N, CTB, CSO.
