Kumvetsetsa FTTP
FTTP, kapena Fiber ku Malo, ndiukadaulo wotsogola kwambiri woperekera mabroadband pomwe ulusi wowoneka bwino umachokera ku netiweki yapakati kupita ku nyumba zogona komanso zamalonda..
Ukadaulowu umakonzedwa kuti ugwiritsidwe ntchito mnyumba koma ndi wosiyana ndi mayankho opangira mabizinesi, zomwe zimagwera pansi pa gulu la optical transport.
FTTP ndi liwu lalikulu lomwe limaphatikiza zonse ziwiri-ku-point (PTP) ndi masinthidwe a point-to-multipoint:
- Point-to-point (PTP) FTTP: Mu PTP network, chingwe chodzipatulira cha fiber optic chimayendetsedwa kwa aliyense wogwiritsa ntchito. Izi zimalola kuthamanga komwe kungakhale kokwezeka kwambiri komanso kusinthasintha kwa magawo ogawana magawo pakati pa onyamula. Nthawi zambiri imaphatikizapo masiwichi a Ethernet owoneka paofesi yapakati (CO) ndi malo kasitomala.
- Malo-to-Multipoint FTTP: Kupanga uku, Nthawi zambiri amatchedwa Passive Optical Network (MON), Zimaphatikizapo chingwe chimodzi cha fiber optic chomwe chimatumikira malo angapo pogwiritsa ntchito ma splitter a kuwala. Mitundu yaukadaulo ya PON imaphatikizapo BPON (Broadband PON), GPON (Gigabit PON), ndi EPON (Ethernet PON), ndi GPON kukhala yolandiridwa kwambiri ndi opereka chithandizo chachikulu, makamaka kunja kwa dera la Asia/Pacific.
Mawu ngati FTTP, FTTH (Fiber Kunyumba), ndi Mtengo wa FTT (Fiber ku x) nthawi zambiri amagwiritsidwa ntchito mosiyana, ngakhale angatanthauze maukonde osiyana pang'ono.
Momwe FTTP imagwirira ntchito
Fiber to the Premises imadziwika chifukwa cha liwiro lake lothamanga kwambiri, kupangitsa kuti ikhale imodzi mwazinthu zofulumira kwambiri zoperekera intaneti zomwe zilipo masiku ano.
Mosiyana ndi Broadband chikhalidwe, zomwe zimafuna malo angapo osinthika monga makabati amsewu ndi zingwe zamkuwa, FTTP imatumiza deta mwachindunji kuchokera ku kusinthana kupita kumalo pogwiritsa ntchito zingwe za fiber optic.
Zingwezi sizimangonyamula kuchuluka kwa deta bwino komanso zimakhala ndi moyo wautali komanso zodalirika kuposa zingwe zamkuwa..
FTTP vs Mtengo wa FTTC: Kufananiza Technologies
Poyerekeza Fiber ndi Malo okhala ndi Fiber ku Cabinet, ndikofunikira kuyeza zabwino ndi zoyipa:
Ubwino wa FTTC:
- Kufikika: FTTC imapezeka m'nyumba zambiri.
- Liwiro: Amapereka liwiro lokwanira pakugwiritsa ntchito intaneti.
- Mtengo: Nthawi zambiri zotsika mtengo.
FTTC Cons:
- Kuchepetsa Liwiro: Copper cabling imachepetsa kuthamanga komwe kungachitike.
- Kumva Kutalikirana: Ubwino wa ntchito umachepa ndi mtunda kuchokera ku nduna.
Ubwino wa FTTP:
- Kuthamanga Kwambiri: Ikhoza kufika mpaka 1 Gigabit pamphindi kapena kupitilira apo.
- Symmetrical Kwezani/Kutsitsa: Ma liwiro otsitsa amatha kufanana ndi liwiro lotsitsa.
- Kupulumutsa Mtengo: Kutha kuchotsa ndalama zachikhalidwe zama foni.
Zoyipa za FTTP:
- Kupezeka: Panopa ndi ochepa poyerekeza ndi FTTC.
- Network Build-Out: Zimatenga nthawi yayitali kukhazikitsa kuposa maukonde a FTTC.
PON ndi Udindo Wake mu Fiber Kumalo
Ma Networks a Passive Optical (MON) amatenga gawo lofunikira pakutumiza kwa FTTP. Ma PON amafalitsa ma optical fiber cabling kwa ogwiritsa ntchito bwino, pogwiritsa ntchito passive (opanda mphamvu) ogawana.
Mapangidwe awa amachepetsa ndalama, amawonjezera kufika, ndipo amakana kufunika kwa mphamvu zamagetsi.
PON imakhala ndi Optical Line Termination (OLT) ku ofesi yapakati ya wothandizira komanso ma Optical Network Units angapo (ONU) ili pafupi kapena pafupi ndi ogwiritsa ntchito’ malo.
Ma PON amakwaniritsa zofunikira za bandwidth, kuwapanga kukhala yankho losinthika la kutumiza kwa FTTP.
Kwa zonse FTTP mayankho ndi chithandizo chaukadaulo, lingalirani zofikira kwa ife!
