1, Tisanatchule FTTR, tiyeni timvetsetse mwachidule zomwe FTTx ndi.
FTTx ndiye chidule cha "Fiber to The x", kutanthauza "fiber to x", pomwe x samayimira kokha malo omwe ulusi umafika, komanso imaphatikizanso zida zamagetsi zamagetsi zomwe zimayikidwa pamalowo, ndikutchula malo omwe amatumizidwa ndi zida za netiweki.Mwachitsanzo,
Chidule cha "B" mu FTTB ndi Building, chomwe chimatanthawuza chingwe cha fiber optic kuchokera ku nyumba kupita ku nyumba, chingwe chamkati cha fiber optic choyikidwa pakhonde, ndikulumikizidwa kwa ogwiritsa ntchito kudzera pa chingwe chopotoka.Malo omwe amagwiritsidwa ntchito ndi amphaka owoneka ndi nyumba imodzi kapena ogwiritsa ntchito pansi.
"H" mu FTTH ndi chidule cha "Home", chomwe chimatanthawuza chingwe cha fiber optic chochokera kunyumba, chingwe cha m'nyumba cha fiber optic chimayikidwa kunyumba kwa wogwiritsa ntchito, ndipo mphaka wa kuwala amaikidwa kunyumba kwa wogwiritsa ntchito.Malo omwe amatumikiridwa ndi mphaka wa kuwala ndi nyumba imodzi.
Chidule "R" mu FTTR amatanthauza kugwirizana CHIKWANGWANI chamawonedwe zipinda ziwiri kapena kuposa m'nyumba wosuta, ndi unsembe wa amphaka kuwala mu zipinda lolingana.Mphaka aliyense wowoneka bwino amapereka chipinda chimodzi kapena zingapo mnyumbamo.
2, Ndiye chifukwa chiyani timafunikira FTTR?Choyamba timvetsetse zosowa za WiFi za wogwiritsa ntchito, zomwe zimayendetsa pulogalamuyi.
Pakadali pano, ambiri mwa ogwiritsa ntchito m'nyumba mwa WiFi amafikirakoONU/ONT, yoperekedwa ndi WiFi yawoyawo kapena yolumikizidwa ndi rauta ya WiFi, yophimbidwa ndi chizindikiro cha WiFi cha rauta.Pali mitundu iwiri yodziwika bwino ya zida za WiFi pamsika: ma frequency amodzi ndi ma frequency awiri.Mafupipafupi amodzi amangothandizira gulu la 2.4G pafupipafupi, ndipo ngakhale lingathe kuthandizira mlingo waukulu wa 300Mbps, zotsatira zenizeni zogwiritsira ntchito zimakhala zoipitsitsa kwambiri chifukwa cha kusokoneza kwakukulu mu gulu la ma frequency.Ma frequency apawiri, amathandizira onse 2.4G ndi 5G ma frequency band.5G WiFi yapita patsogolo mwachangu, koma kuthekera kwa ma siginecha a 5G band WiFi kudutsa makoma ndikofooka, zomwe zimabweretsa kusokoneza kwakukulu kwa mabanja akulu ndi ogwiritsa ntchito ambiri.
Pakali pano, pali mitundu itatu ikuluikulu ya ziwembu za WiFi zapakhomo pamsika: dongosolo la router cascade ndikukhazikitsa rauta ya master pa cat optical, ndipo chipinda chilichonse chimakhala ndi rauta ya akapolo.Ma routers a master ndi akapolo amalumikizidwa pogwiritsa ntchito zingwe za Gulu 6.Chifukwa cha kuchepa kwa chiwerengero cha ma doko a LAN pa rauta yaikulu, chiwerengero cha ma routers achiwiri nthawi zambiri sichidutsa 4. Ngati izi zidutsa malire, masinthidwe owonjezera ayenera kuwonjezeredwa pa rauta yaikulu.Chifukwa chogwiritsa ntchito mawaya olumikizirana, dongosololi limatha kutsimikizira kulumikizana kwa gigabit pakati pa njira za master ndi akapolo;Choyipa ndichakuti zingwe za Gulu 6 zimafunikira kuyikidwa mkati mwa nyumba, zomwe zimakhala ndi zovuta zina zokhazikitsa ndipo zitha kukhudza kukongola.Kuphatikiza apo, zimakhala zovuta kusintha basi WiFi SSID ya chipangizo chilichonse.
Amphaka amphamvu amagawidwa kukhala amphaka opangira mawaya ndi amphaka opanda zingwe.Lumikizani mphaka wamagetsi wama waya ku doko la LAN la rauta pogwiritsa ntchito chingwe cha Gulu 6;Mphaka wamagetsi opanda zingwe ndi rauta yopanda zingwe yomwe imatha kulumikizidwa munjira iliyonse yamagetsi mnyumba (makamaka potengera khoma), ndipo mphaka wamagetsi wama waya amatha kuphatikizidwa ndi amphaka ambiri opanda zingwe kuti agwiritse ntchito.Chizindikiro pakati pa amphaka opangira mawaya ndi amphaka opanda zingwe amatumizidwa kudzera mu mizere yamagetsi, ndipo liwiro la netiweki limakhudzidwa kwambiri ndi mtundu wa mawaya amagetsi amkati kwa ogwiritsa ntchito.Kuphatikiza apo, ma terminals nthawi zambiri amatha kulumikizidwa akamayendayenda mu ma AP osiyanasiyana.
Chiwembu cholozera mwana kupita kwa mwana chimaphatikizapo rauta ya kholo limodzi ndi ma router angapo a ana, ndipo rauta iliyonse imatha kulumikizidwa kudzera pa WiFi.Chifukwa chazovuta zosadutsa makoma a ma siginecha a WiFi pakati pa ma routers, mphamvu ya bandwidth ya chiwembuchi imakhudzidwa kwambiri ndi chilengedwe.Pali njira yopangira mbewu ndi amayi yomwe imagwiritsa ntchito WiFi ndi mizere yamagetsi pakupatsirana pakati pa ma routers amwana ndi amayi nthawi imodzi, zomwe zathandizira luso lolowera khoma la WiFi mpaka pamlingo wina.Komabe, mphamvu zonse za bandwidth zimatsalirabe kwambiri poyerekeza ndi dongosolo la router cascade.
3. Ubwino wa FTTR
FTTR imagwiritsa ntchito chingwe chimodzi chachikulu chowunikira komanso zingwe zingapo zaakapolo zowunikira kuti zipezeke m'nyumba za WiFi.Zingwe zazikuluzikulu ndi akapolo owoneka bwino zimalumikizidwa ndi gulugufe kapena zingwe zobisika zowonekera.Poyerekeza ndi ziwembu pamwamba, FTTR ali ubwino zotsatirazi: (1) gulugufe kapena zobisika kuwala zingwe zosavuta anagona kuposa Class 6 zingwe, ndi kuyala zingwe zobisika kuwala sikukhudza aesthetics m'nyumba;(2) The pazipita network liwiro pafupi aliyense kuwala mphaka kwa owerenga gigabit akhoza kufika 1000Mbps;(3) Kuthamanga kwa maukonde okhazikika, kusinthasintha kokhazikika pakati pa amphaka owala;(4) Kutalika kwa moyo wa ulusi wa kuwala kumadutsa zaka 20, ndipo bandwidth ndi pafupifupi yopanda malire.
Chifukwa cha zabwino zomwe zili pamwambapa za FTTR, opanga zida zambiri akuikapo ndalama pantchito iyi, monga:
Huawei Home automation=FTTR+Hongmeng
FTTR all-optical WiFi, kudzera mu kuphatikiza kwabwino kwa amphaka ambuye ndi akapolo owoneka bwino, imagwiritsa ntchito ulusi wowoneka bwino m'malo mwa chingwe cha netiweki kuphimba gigabit burodi bandi kuchipinda chilichonse chabanja, chomwe ndi maziko olumikizirana ndi Home automation.Opaleshoni ya Hongmeng ndiye njira yanzeru yogwiritsira ntchito nthawi ya intaneti ya Chilichonse, yomwe ingagwiritsidwe ntchito pa mawotchi, mafoni a m'manja, zomvetsera, ma TV ndi zipangizo zina, ndipo imathanso kulumikizidwa ndi kukhudza, Pangani malo apamwamba kwambiri ndikugwirizanitsa. ndi wina ndi mzake.
