1, Ngaphambi kokwethula i-FTTR, ake siqonde kafushane ukuthi iyini i-FTTx.
I-FTTx isifinyezo se-"Fiber To The x", sibhekisela ku-"fiber to x", lapho u-x engamele nje kuphela indawo lapho i-fiber ifika khona, kodwa futhi ihlanganisa imishini yenethiwekhi yokubona efakwe kuleyo ndawo, futhi icacisa indawo ehlinzekwa imishini yenethiwekhi. Ngokwesibonelo,
Isifinyezo esithi "B" ku-FTTB sithi Isakhiwo, esibhekisela kukhebula le-fiber optic ukusuka esakhiweni kuye kwelinye, intambo ye-fiber optic yasendlini ebekwe ephasejini, futhi ixhunywe kubasebenzisi ngekhebula ephothiweyo. Indawo esetshenziswa ikati elikhanyayo yibhilidi elilodwa noma abasebenzisi besitezi esisodwa.
U-"H" ku-FTTH isifinyezo se-"Ekhaya", esibhekisela kukhebula le-fiber optic elisuka ekhaya, intambo ye-fiber optic yasendlini ibekwe ekhaya lomsebenzisi, futhi ikati elibonakalayo lifakwa ekhaya lomsebenzisi. Indawo esetshenziswa ikati elikhanyayo iyikhaya elilodwa.
Isifinyezo esithi "R" ku-FTTR sibhekisela ekuxhumekeni kwe-fiber optic emakamelweni amabili noma ngaphezulu ekhaya lomsebenzisi, kanye nokufakwa kwamakati abonakalayo emakamelweni ahambisanayo. Ikati ngalinye elibonayo linikeza igumbi elilodwa kuya kwangaphezulu ekhaya.
2, Pho kungani sidinga i-FTTR? Masiqale siqonde izidingo ze-WiFi zomsebenzisi wamanje, ezishayela uhlelo lokusebenza.
Njengamanje, iningi labasebenzisi basekhaya i-WiFi yangaphakathi ifinyelelwaI-ONU/ONT, ehlinzekwa yi-WiFi yabo noma exhunywe ku-WiFiumzila, imbozwe isignali ye-WiFi yomzila. Kunezinhlobo ezimbili ezijwayelekile zamadivayisi we-WiFi emakethe: imvamisa eyodwa kanye nefrikhwensi ekabili. I-frequency eyodwa isekela kuphela i-2.4G frequency band, futhi nakuba ingasekela isilinganiso esiphezulu se-300Mbps, umphumela wangempela wokusetshenziswa mubi kakhulu ngenxa yokuphazanyiswa okuphezulu kuleli bhande lokuvama. Imvamisa ekabili, isekela womabili amabhendi efrikhwensi angu-2.4G kanye ne-5G. I-5G WiFi ithuthuke ngesivinini, kodwa amandla amasiginali we-5G we-WiFi okudlula ezindongeni abuthakathaka, okuletha ukuphazamiseka okukhulu kweminye imizi emikhulu nabasebenzisi abaningi.
Njengamanje, kunezinhlobo ezintathu eziyinhloko zezinhlelo zokuhlanganisa i-WiFi yasekhaya emakethe: iumzilai-cascade scheme iwukumisa i-masterumzilaekatini le-optical, futhi igumbi ngalinye lifakwe isigqilaumzila. Amarutha ayinhloko kanye nesigqila axhunywe kusetshenziswa izintambo zeSigaba 6. Ngenxa yomkhawulo wenombolo yezimbobo ze-LAN kokuyinhlokoumzila, inani lamarutha esibili ngokuvamile alidluli u-4. Uma lokhu kweqa umkhawulo, amaswishi engeziwe adinga ukungezwa endaweni eyinhloko.umzila. Ngenxa yokusetshenziswa koxhumano olunezintambo, lolu hlelo lungaqinisekisa ukuxhumana kwe-gigabit phakathi kwemizila eyinhloko neyezigqila; Okubi ukuthi izintambo zeSigaba 6 zidinga ukubekwa ngaphakathi kwendlu, enobunzima obuthile bokusebenzisa futhi engase ithinte ubuhle. Ukwengeza, kunzima ukwenza ngokuzenzakalelayoshintshai-WiFi SSID yedivayisi ngayinye.
Amakati anamandla ahlukaniswe amakati anamandla anentambo namakati anamandla angenantambo. Xhuma ikati lamandla elinentambo embobeni ye-LAN yeumzilausebenzisa ikhebula leSigaba 6; Ikati lamandla angenantambo liyi-wirelessumzilaengaxhunywa kunoma iyiphi indawo yamandla endlini (okungcono indawo ephuma odongeni), futhi ikati lamandla elinentambo lingabhangqwa namakati amaningi angenantambo asetshenziswayo. Isignali ephakathi kwamakati anamandla anentambo namakati anamandla angenantambo idluliselwa ngezintambo zikagesi, futhi isivinini senethiwekhi sithintwa kakhulu ikhwalithi yezintambo zikagesi zasendlini kubasebenzisi. Ngaphezu kwalokho, amatheminali ajwayele ukunqanyulwa lapho ezulazula kuma-AP ahlukahlukene.
Isikimu somzila wengane uye enganeni sihlanganisa umzali oyedwaumzilakanye namarutha ezingane amaningi, futhi ngalinyeumzilaingaxhunywa nge-WiFi. Ngenxa yobunzima bokungadluli ezindongeni zamasignali e-WiFi phakathi kwamarutha, amandla omkhawulokudonsa walolu hlelo athintwa kakhulu indawo ezungezile. Kunomkhiqizo womzila wembewu noma umama osebenzisa i-WiFi nezintambo zikagesi ukuze udlulise phakathi kwamarutha engane nomama ngesikhathi esisodwa, okuthuthukise ikhono lokungena odongeni le-WiFi ngezinga elithile. Noma kunjalo, umthamo womkhawulokudonsa jikelele usabambezeleka kakhulu uma uqhathaniswa neumzilauhlelo lwe-cascade.
3. Izinzuzo ze-FTTR
I-FTTR isebenzisa ikhebula elibonakalayo elilodwa eliyinhloko kanye nezintambo eziningi zokubuka zesigqila ukuze kufakwe i-WiFi yasendlini. Izintambo eziyinhloko nezigqila ze-optical zixhunywe uvemvane noma izintambo ezibonakalayo ezifihliwe. Uma kuqhathaniswa nalezi zinhlelo ezingenhla, i-FTTR inezinzuzo ezilandelayo: (1) uvemvane noma izintambo ezibonakalayo ezifihliwe kulula ukuzibeka kunezintambo ze-Class 6, futhi ukufakwa kwezintambo ezibonakalayo ezifihliwe akuthinti ubuhle bangaphakathi; (2) Isivinini esiphezulu senethiwekhi eduze kwanoma yiliphi ikati elibonakalayo labasebenzisi be-gigabit singafinyelela ku-1000Mbps; (3) Ijubane lenethiwekhi elizinzile, ukushintsha okuzinzile kwetheminali phakathi kwamakati abonakalayo; (4) Ukuphila kwama-optical fibers kudlula iminyaka engu-20, futhi umkhawulokudonsa cishe awupheli.
Ngenxa yezinzuzo ezingenhla ze-FTTR, abakhiqizi bemishini abaningi njengamanje batshala imali kulo mkhakha, njenge:
I-Huawei Home automation=FTTR+Hongmeng
I-FTTR all-optical WiFi, ngokusebenzisa inhlanganisela ephelele yamakati abonayo ochwepheshe kanye nesigqila, isebenzisa i-optical fiber esikhundleni sentambo yenethiwekhi ukumboza i-gigabit broadband kuwo wonke amagumbi omndeni, okuyisisekelo sokuxhuma se-Home automation. Uhlelo lokusebenza lwase-Hongmeng luwuhlelo oluhlakaniphile lwetheminali enkathini ye-inthanethi Yakho Konke, olungasetshenziswa emawashini, omakhalekhukhwini, okulalelwayo, omabonakude namanye amadivaysi, futhi lungaxhunywa ngokuthinta, Yenza itheminali enkulu futhi uxhume. nomunye.
Inethiwekhi ethengisa imikhiqizo eshisayo ye-Shenzhen Haidwiwei Optoelectronics Technology Co., Ltd. ihlanganisa izinhlobo ezahlukene zeI-ONUimikhiqizo yochungechunge, kuhlanganise ne-ACI-ONU/ukuxhumanaI-ONU/ehlakaniphileI-ONU/ibhokisiI-ONU, njll. OkungenhlaI-ONUimikhiqizo yochungechunge ingasetshenziselwa izidingo zenethiwekhi ezimeni ezahlukahlukene. Yamukela wonke umuntu ukuthi eze futhi abe nolwazi oluningiliziwe lobuchwepheshe lomkhiqizo.
