FTTH. Ukadaulo
Choyamba, FTTH ndi chiyani?
Ndipo mudamvapo za FTTH?
Kapena ukadaulo wapanja wa fiber fiber
Kodi ili ngati DSL kapena pafupi ndi m'badwo wachinayi 4G
Zachidziwikire, kwa ichi kapena icho, mu mizere ikubwerayi tidzayankha mafunso awa mokongola komanso mwatsatanetsatane.
FTTH (CHIKWANGWANI kunyumba):
Kapena fiber fiber optics ndiukadaulo wofalitsa chidziwitso ndi chidziwitso mkati mwa mawaya agalasi mothamanga kwambiri wofanana ndi kuthamanga kwa kuwala, kutanthauza kuti mutha kulingalira kuchuluka kopanda malire komanso kopanda malire kwa kuchuluka kwa chidziwitso ndi chidziwitso. mafayilo akulu akulu a gigabyte m'masekondi, akusewera pa intaneti osasokonezedwa, kutenga nawo gawo pazolumikizana ndi makanema anu, ndikuwonera IPTV pa intaneti.
FTTH Kuwala CHIKWANGWANI:
Njira zabwino kwambiri, zaposachedwa komanso zosasunthika kwambiri zolumikizirana zomwe zikupezeka pa intaneti, kuwonjezera pa kuthamanga kwake kosangalatsa.Ndiukadaulo wokhazikika womwe sukukhudzidwa ndi zinthu zakunja monga kusokonezedwa, mphepo, kutentha kwakunja, ndi zina.
Kusiyanitsa kwa zolemba:
FTTN .. CHIKWANGWANI ku Node.
Viber mpaka kufika posonkhanitsa.
FTTC .. CHIKWANGWANI ku Kuthetsa.
CHIKWANGWANI panjira.
FTTB .. CHIKWANGWANI ku Nyumbayi.
Viber mpaka mnyumbayo.
FTTH .. CHIKWANGWANI Kunyumba.
Viber kunyumba.
FTTH imatanthauza kuti ulusiwo umafika komwe amakhala, pomwe FTTB imayimira kulumikizana kokha mnyumbayo osati nyumba kapena malo okhala. FTTC ndi FTTN zimatanthauzanso kuti CHIKWANGWANI chimafikira ochepera 300 m koyamba ndikupitilira 300 m kwachiwiri, kusiyanasiyana uku kumawonekeranso pamtundu komanso kuthamanga kwa kulumikizana.
Magawo amaneti ndi momwe amagwirira ntchito:
Zipangizo zomwe zimagawika kapena malo ogulitsira amatchedwa:
(OLT: Optical Line Termination).
Ndipo ili ndi makhadi angapo, khadi iliyonse ili ndi madoko angapo otchedwa:
(PON: Passive Optical Network).
Imalumikizidwa ndi ulusi umodzi wamtundu womwe umatumiza ndikulandila pamawonekedwe awiri osiyana siyana. Kufikira malo okwanira 64 amatumizidwa pa doko lirilonse pogawa ulusiwo kukhala ulusi wokhala ndi ziboda ndipo ulusiwo umalumikizidwa pa terminal:
(ONT: Optical Network Termination).
Tsitsani (Tsitsani Data):
Mukamagwiritsa ntchito protocol ya GPON, liwiro lonse lophatikizidwa ndi ma gigabits a 2.488 pakukula kwa 1490 nm. Zida zonse zimalandira zikwangwani zonse ndipo zimangovomereza zidziwitso zomwe zimatumizidwa kuzida zolandirira. Kuthamanga kwakukulu komwe kumathandizidwa pa terminal imodzi ndi 100Mbps.
Kwezani Data:
Liwiro lophatikizika lonse ndi ma gigabits a 1.244 pogwiritsa ntchito kutalika kwa 1310 nm. Chida chilichonse chodulira chimatumiza zizindikilo zake munthawi yomwe idakonzedweratu komanso nthawi zonse ikusintha, kutengera zofunikira, mulingo wabwino, liwiro logwirizana, komanso kuchulukana.
Tsitsani (Tsitsani Kanema):
Kutalika kwa 1550 nm kumagwiritsidwa ntchito popatsira makanema. Kuthamanga kwakukulu komwe kumathandizidwa pa terminal imodzi ndi 100Mbps.
Kuthamanga kwapafupipafupi komwe mukufuna panyumba yanu:
Ngati mukufunsa za liwiro loyenera la FTTH kunyumba kwanu, liwiro lomwe nyumbayo ikufunika limafika 40 MB, kuti mupindule ndi mapulogalamu amacheza pavidiyo, masewera, onerani ma TV apamwamba, komanso kutsitsa mafayilo nthawi zonse komanso mosalekeza.
Ndondomeko za FTTH:
Zimatengera malamulo monga:
1 - GPON.
2 - EPON.
3-BPON.
Ndipo yomwe yangogwiritsa ntchito kumene ndi giga .. GPON
(GPON: Gigabit Passive Optical Network).
Zambiri zimafalikira pamapaketi otchedwa .. GEM
(GEM: GPON Encapsulation Module).
Ubwino wa netiweki ya FTTH ndikuyerekeza kwake ndi netiweki yamkuwa DSL:
1- Kuthamanga kwambiri.
2- Kulondola komanso kuyera kwa zizindikilo.
3- Kuthamanga sikuchepera ndikukula mtunda. Makasitomala akutali kwambiri akhoza kupeza liwiro lofanana ndi kasitomala wapafupi.
4- Kusinthasintha kwa ntchito komanso kuwapatsa mosavuta.
5- Kutha kwake kuthandizira ntchito zamtsogolo.
6- Kutha kusintha mphamvu ndi kuchuluka kwa madoko kwa kasitomala posintha chipangizocho.
7- Mtunda wopitilira 8 km mpaka 60 km kukachitika kuti mwambowo sunakhale nthambi.
Zomwe zimafalitsa pang'onopang'ono ukadaulo wa FTTH:
Kuchedwa kumeneku kumachitika chifukwa chakuti zida zaukadaulozi ndizokwera mtengo kwambiri, kuphatikiza pakuvuta kusamalira ndikuyika ulusi wamafuta ngati wawonongeka. Koma chopinga chachikulu ndikulephera kusinthiratu zomangamanga zomwe zilipo ndi zida zofunikira paukadaulo uwu, kuphatikiza poti wogwiritsa ntchito wamba safunika kuthamanga kwambiri. Zifukwa ziwirizi zimapangitsa kulumikizana kwachikhalidwe ndi waya wamkuwa kukupitabe mpaka pano.
Tikukufunirani, otsatira athu ofunika, kukhala athanzi labwino
