Okokuqala, ngaphambi kokwethula i-FTTR, sivele siqonde ukuthi iyini i-FTTx.
I-FTTx isifinyezo se-"Fiber To The x" se-"fiber to x", lapho u-x engamele nje kuphela isayithi lapho i-fiber ifika khona, kodwa futhi ihlanganisa idivayisi yenethiwekhi yokubona efakwe kusayithi futhi ikhomba indawo lapho idivayisi yenethiwekhi isebenza khona. . Isibonelo, u-"B" ku-FTT B isifinyezo se-Building, ibhekisela ku-fiber optical esakhiweni, intambo ye-optical yasendlini eya ephaseji, ngenkathi ixhunywe kumsebenzisi ngepheya esontekile, indawo laphoI-ONUusebenzela isakhiwo esisodwa noma umsebenzisi oyedwa waphansi.
Igama elithi "H" ku-FTTH lifushane elithi Ikhaya, elibhekisela ku-optical fiber ekhaya, intambo yasendlini yasendlini eya ekhaya lomsebenzisi, ngenkathi ifakwe ekhaya lomsebenzisi, indawoI-ONUukhonza yikhaya elilodwa.
U-"R" ku-FTTR isifinyezo seGumbi, esisho i-optical fibre emagumbini angu-2 noma ngaphezulu endlini yomsebenzisi, futhi afakwe ekamelweni elihambisanayo, ngalinye.I-ONUinikezela ngegumbi eli-1 kuya kwangaphezulu ekhaya.
Okwesibili, kungani-ke udinga i-FTTR, masiqale siqonde izidingo zomsebenzisi wamanje we-WiFi, udinga ukukhuthaza uhlelo lokusebenza.
Njengamanje, abasebenzisi abaningi basekhaya bane-WiFi ngokusebenzisa i-I-ONU/ ONT, ehlinzekwa yi-Wifi yabo noma exhunywe ku-Wifiumzila, embozwe isignali ye-WiFi yeumzila. Amadivayisi ajwayelekile we-wifi emakethe ayimvamisa eyodwa kanye nefrikhwensi ekabili. Ifrikhwensi eyodwa isekela kuphela ibhendi yefrikhwensi engu-2.4G. Nakuba ingasekela isilinganiso esiphezulu esingu-300Mbps, umphumela wokusetshenziswa wangempela mubi kakhulu ngoba ukuphazamiseka kwaleli bhendi yefrikhwensi kukhulu uma kuqhathaniswa. I-Dual-frequency, usekelo lwe-2.4G kanye ne-5G yamabhendi amafrikhwensi amabili. I-5G WiFi ithuthukisiwe ngokwesilinganiso, kodwa ikhono lesignali ye-WiFi yebhendi ye-5G yokungena odongeni alinamandla, okuletha ukuphazamiseka okukhulu kwezinye izinhlobo zemindeni emikhulu, imindeni enabasebenzisi abaningi.
Njengamanje, kunezixazululo ze-WiFi yendlu yonke emakethe, ikakhulukazi ezigabeni ezintathu ezilandelayo: iumzilai-cascade scheme iwukusetha okuyinhlokoumzilakweI-ONU, ikamelo ngalinye libekwe kusukelaumzila, inkosi nesigqilaumzilangentambo ye-CAT6. Kukhawulelwe ngenombolo yokuyinhlokoumzilaIzimbobo ze-LAN, inani lamarutha ezinceku ngokuvamile alidluli u-4, uma lidlula, i-shintshaidinga ukungezwa ku-masterumzila. Ngenxa yokusetshenziswa koxhumano olunezintambo, lolu hlelo lungaqinisekisa ukuxhumana kwe-Gigabit phakathi kwemizila eyinhloko neyezigqila; okubi ukuthi ikhebula le-CAT6 lidinga ukuhlelwa endlini, okunzima ukulisebenzisa, lingathinta ukubukeka, futhi lidinga ukuzenzekelayoshintshaidivayisi ngayinye WiFi SSID.
UgesiI-ONUzihlukaniswa zibe zikagesi ezinezintamboI-ONUkanye nogesi ongenazintamboI-ONU. Izintambo ze-CAT6 zixhunywe embobeni ye-LAN ye-umzila; ugesi ongenazintamboI-ONUiyi-wirelessumzilaixhunywe kunoma iyiphi isokhethi yamandla endlini (okungcono isokhethi odongeni), kanye nogesi onezintamboI-ONUingabhangqwa ne-multiple wireless ElectricI-ONU. Isignali phakathi kukagesi onezintamboI-ONUkanye ne-wireless ElectricI-ONUidluliselwa ngentambo yamandla, futhi isivinini senethiwekhi sithintwa kakhulu ikhwalithi yezintambo zikagesi zasendlini, futhi itheminali ngokuvamile kulula ukuwisa ulayini lapho izulazula ku-AP ngayinye.
Isikimu somzila esingaphansi komzali sihlanganisa umzali oyedwaumzilakanye nama-subrouters amaningi okuxhumana kwe-Mesh nge-WiFi. Ngenxa yokuthi amasignali e-WiFi phakathi kwama-routers anzima ukuthi angangeni odongeni, amandla omkhawulokudonsa walolu hlelo athintwa kakhulu imvelo. Kunomkhiqizo womzila wengane nomama, osebenzisa kokubili i-WiFi kanye nentambo yamandla ukuze udlulise, okwenza ngcono ikhono lokungena odongeni le-WiFi ngezinga elithile, kodwa igebe lamandla omkhawulokudonsa lisasobala uma liqhathaniswa neumzilauhlelo lwe-cascade.
Okwesithathu. Izinzuzo ze-FTTR
I-FTTR isebenzisa ukumbozwa kwe-WiFi yasendlini, izintambo zokukhanya eziyinhloko nezigqila, i-FTTR inezinzuzo ezilandelayo: (1) ikhebula le-butterfly optical noma ikhebula le-optical elifihliwe uma liqhathaniswa nekhebula le-CAT6, ikhebula lokukhanya elifihliwe alithinti ukubukeka kwangaphakathi; (2) isivinini esiphezulu senethiwekhi eduze kwabasebenzisi be-Gigabit singafinyelela ku-1000Mbps; (3) ijubane lenethiwekhi elizinzile kanye nokushintsha kwesiphetho okushelelayo phakathi kwe-ONU; (4) ngaphezu kweminyaka engama-20, umkhawulokudonsa cishe awunamkhawulo.
Ngenxa yezinzuzo ezingenhla ze-FTTR, abathengisi bemishini abaningi njengamanje batshala imali kule ndawo, njenge:
IHuawei Smart Home =FTTR + Hongmeng
I-FTTR ye-WiFi ebonakalayo egcwele, ngokusebenzisa ukuhlanganiswa okuphelele kweI-ONU, nge-optical fiber esikhundleni sekhebula, i-gigabit broadband, emboza wonke amagumbi omndeni, iwukuxhunywa kwesisekelo somndeni, futhi uhlelo lokusebenza lwase-Hongmeng yonke inkathi ye-inthanethi yesistimu yokusebenza yetheminali ehlakaniphile, ingasetshenziswa kumawashi, umakhalekhukhwini. , okulalelwayo, i-TV namanye amadivaysi, kungathinta ukuxhumana, i-Hongmeng FTTRI-ONU
vumela amatheminali amakhulu namancane ekhaya, akhe i-superterminal, ukuxhumana nomunye nomunye.
