Optical Network Terminal (ONT) yog ib qho cuab yeej siv rau kev nkag mus rau fiber ntau optic broadband tes hauj lwm, feem ntau yog siv los hloov cov teeb liab fiber ntau rau hauv cov teeb liab hluav taws xob siv hauv tsev. OLT (Optical Line Terminal) yog cov cuab yeej tseem ceeb ntawm fiber ntau optic nkag network, feem ntau yog lub luag haujlwm rau kev faib, tswj, thiab tswj cov teeb liab kho qhov muag. Hauv kev siv tiag tiag, optical modem ONT thiab OLT yuav tsum tau txuas nrog los ntawm ntau hom kev sib txuas kom ntseeg tau cov ntaub ntawv xa mus. Hauv qab no, peb yuav muab cov lus qhia ntxaws ntxaws rau hom kev sib txuas ntawm Lub Teeb Cat OLT.
1. Optical interface
Optical interface yog hom kev sib txuas tseem ceeb ntawm optical modem OLT thiab ONT, feem ntau yog siv rau kev xa cov teeb liab fiber ntau. Optical interface feem ntau yog siv tus qauv SC / APC interface lossis LC / PC interface. SC / APC yog ib hom kev sib txuas uas siv tau rau kev sib kis ntev, thaum LC / PC feem ntau yog siv los tsim kev sib txuas me me.
2. Ethernet interface
Ethernet interface yog hom kev sib txuas yooj yim ntawm optical modem OLT thiab cov khoom siv hauv network, thiab yog lub ntsiab lus tseem ceeb hauv tsev niaj hnub lossis kev lag luam network. Ethernet interface feem ntau yog siv los xa cov ntaub ntawv Ethernet raws tu qauv.
3. POTS interface
Lub POTS interface yog ib lub xov tooj kab sib txuas uas yog siv los xa cov suab analog teeb liab. Hauv kev sib txuas hauv xov tooj ib txwm muaj, kab xov tooj txuas mus rau ib lub tsev, yog li qhov kho qhov muag modem OLT yuav tsum tau txhawb nqa cov kev pabcuam hauv xov tooj los ntawm kev nkag mus rau POTS interface.
4. WLAN interface
WLAN interface feem ntau yog siv los ua kom muaj kev sib txuas hauv wireless thiab txhawb nqa IEEE 802.11 wireless hauv cheeb tsam hauv cheeb tsam network raws tu qauv. Los ntawm WLAN interfaces, cov neeg siv hauv tsev thiab kev lag luam tuaj yeem ua tiav kev sib txuas ntawm ntau lub cuab yeej thiab nthuav dav kev pabcuam wireless network.
5. USB interface
USB interface tuaj yeem txuas tau ntau yam USB li, xws li tshuab luam ntawv, koob yees duab, cov khoom siv cia, thiab lwm yam. Los ntawm kev txuas mus rau USB interface, optical modem OLT tuaj yeem faib cov khoom siv no ua cov peev txheej hauv network, ua tiav cov ntaub ntawv sib pauv yooj yim dua.
6. CATV interface
CATV interface yog tsuas yog siv rau kev sib kis ntawm cable TV teeb liab, txhawb cov tsoos cable TV phaib thiab fiber optic TV teeb liab. Zoo ib yam li POTS interface, dhau ntawm CATV interface, Optical Cat OLT tuaj yeem muab cov neeg siv nrog cov kev pabcuam hauv TV.
7. SIP interface
SIP interface yog tus qauv raws tu qauv siv rau kev xa suab thiab video, feem ntau yog siv rau kev lag luam network video conferencing. Los ntawm SIP interface, optical modem OLT tuaj yeem txuas rau lub rooj sib tham cov khoom siv thiab txhawb kev sib tham video.
Nyob rau hauv cov ntsiab lus, cov saum toj no qhia txog lub ntsiab interface hom rau kho qhov muag modem OLT kev twb kev txuas, thiab ntau hom interfaces txhawb kev sib txawv daim ntawv thov scenarios thiab ntaus ntawv hom. Hauv kev xaiv tiag tiag, nws yog qhov yuav tsum tau xaiv thiab teeb tsa raws li qhov xwm txheej tiag tiag kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm lub network.
