Ubuchwepheshe be-Fiber-optic Ethernet wukuhlangana nokuthuthukiswa kobuchwepheshe obubili obuyinhloko bezokuxhumana, okuyi-Ethernet kanye namanethiwekhi optical. Bugxila ezinhlelweni ze-Ethernet namanethiwekhi optical, njengezinhlelo zokusebenza ezivamile ze-Ethernet, intengo ephansi, inethiwekhi eguquguqukayo, ukuphatha okulula, okuphezulu. ukuthembeka kanye nomthamo omkhulu wamanethiwekhi optical.
Ijubane eliphezulu nomthamo omkhulu we-Ethernet optical iqeda ibhodlela lomkhawulokudonsa elikhona phakathi kwe-LAN ne-WAN, umthakathi uzoba isakhiwo senethiwekhi esisodwa sokuguqula izwi, idatha kanye nevidiyo esikhathini esizayo.Imikhiqizo ye-Fiber-optic Ethernet ingasebenzisa izinsizakalo zokuxhumana ze-WAN isebenzisa Amafomethi ephakethe le-Ethernet asebenzisa amadivayisi e-Ethernet.Okwamanje, i-fiber-optic Ethernet ingafinyelela izivinini ezijwayelekile ze-Ethernet ezingu-10Mbps, 100Mbps, kanye no-1Gbps.
Amadivayisi e-Fiber-optic Ethernet asekelwe ku-Layer 2 LANamaswishi, Isendlalelo sesi-3 se-LANamaswishi, amadivaysi e-SONET, kanye ne-DWDM.Ezinye izinkampani zenze i-fiber-optic Ethernetamaswishienikeza izici ezihlukahlukene ukuze kuqinisekiswe ikhwalithi engcono kakhulu yesevisi (njengokuhlunga amaphakethe kanye nokuphathwa kokuminyana).Lo mkhiqizo ungase udinge lobu buchwepheshe obubalulekile nezici ezilandelayo: ukwethembeka okuphezulu, ukuminyana kwezimbobo eziphezulu, kanye neziqinisekiso zekhwalithi yesevisi.I-Fiber- I-optic Ethernet iyonga kakhulu futhi isebenza kahle kakhulu kunokunye ukuxhumana kwe-broadband, kodwa kuze kube manje isetshenziswe kuphela ezakhiweni zamahhovisi noma ezakhiweni lapho i-fiber isivele ibekiweInani lesu lale ndlela entsha yokusebenzisa i-Ethernet ayilona. kukhawulelwe ekufinyeleleni okushibhile. Ingasetshenziselwa kokubili ukufinyelela amanethiwekhi kanye namanethiwekhi omgogodla wendawo kumanethiwekhi abahlinzeki besevisi.Ingasetshenziswa kuphela Kusendlalelo sesi-2 noma njengendlela esebenzayo yokuqalisa izinsizakalo Zesendlalelo sesi-3. Ingakwazi ukusekela i-IP, i-IPX nezinye izimiso ezijwayelekile.Ngaphezu kwalokho, ngenxa yokuthi iseyi-LAN ngokwemvelo, ingasetshenziswa ukusiza abahlinzeki besevisi ukuphatha ukuxhumana phakathi kwama-LAN ezinkampani nama-LAN ezinkampani namanye amanethiwekhi.
Isikimu sokufinyelela se-fiber-optic Ethernetamaswishi
Njengoba kuboniswe esithombeni, idivayisi eyinhloko yenethiwekhi iyifayibhashintshaibekwe ekamelweni lamaseli noma ekamelweni lekhompyutha yokwakha. I-fibershintshaixhunywe onqenqemeni lwe-inthanethiumzilanoma iqoqoshintshangenani elingu-1000 M/100 M ngokusebenzisa i-fiber optical ukuze kusetshenziswe ukufinyelela kwenethiwekhi yeselula ku-inthanethi.
I-fiber opticalshintshaixhunywe neyunithi yenethiwekhi yokubona ebekwe ekhaya lomsebenzisi noma ikhadi le-Ethernet elakhelwe ngaphakathi le-fiber Ethernet ngesilinganiso se-duplex 100M nge-optical fibre kanye nemodi yokukhomba-kuya-iphuzu. Ukuxhumana phakathi kwe-fiber opticalshintshafuthi iyunithi yenethiwekhi ye-optical ngokusebenzisa i-optical fiber ukufinyelela kwesivinini esiphezulu ku-inthanethi imodi ye-single-fiber yezindlela ezimbili.
Uma kuqhathaniswa nokufinyelela okukhona kwe-5 - line - based based LAN broadband, lolu hlelo lokufinyelela lunezici ezilandelayo ezivelele:Isixazululo se-FTTH esingabizi kakhulu; ukuqeda phansiamaswishi, igumbi leseli kuphela eliyindawo esebenzayo, enciphisa izindleko zokulungisa;IyodwashintshaI-node ekamelweni lamaseli ingathuthukisa ngempumelelo ukusetshenziswa kweshintshaitheku. Umkhawulokudonsa ophezulu we-Ultra, izikhathi eziyi-100 ADSL; Ibanga elide lokufinyelela; Ukuqapha okukude kwenethiwekhi yemojuli ye-photoelectric yembobo ngayinye.Ngokuhlukaniswa kwechweba kanye nemisebenzi yokulawula umkhawulokudonsa wembobo; Umsebenzi wokuphatha inethiwekhi ye-Web Server enamandla.Lolu hlelo lufaneleka ngokukhethekile kubasebenzisi abajwayelekile bezindawo zokuhlala, izakhiwo zamahhovisi, izikole nezibhedlela, kanye nabasebenza ngocingo kanye nabaqhubi benethiwekhi abahlala khona.
Isifinyezo:
Uma kubhekwa inkambiso evamile yokuthuthuka, ukusetshenziswa kwe-optical fibre kunethiwekhi yokufinyelela kufanele kuqala kumiselele intambo yokuphakelayo ngefayibha yokuphakelayo, bese kuqhubekela kumsebenzisi. Kodwa-ke, izindleko ziya ngokuya ziba phezulu, okwamanje, i-optical fibre ngokuvamile ifinyelela kuphela ebhokisini lokusabalalisa eliseceleni komgwaqo, okuyi-business access point (SAP).
Umgomo omkhulu wenethiwekhi yokufinyelela i-fiber optical ukukhuthaza i-optical fiber kubasebenzisi bezindawo zokuhlala. Njengamanje, akulona iqiniso ukuletha i-fiber optical ekhaya, ngoba intengo ye-fiber optical isabiza kakhulu, ngakho-ke ukusetshenziswa kokufinyelela kwe-fiber optical Ethernet kuyisixazululo esingabizi kakhulu se-FTTH.
