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 ekushintsheni kwe-Layer 2 LAN, ukushintsha kweLayer 3 LAN, amadivayisi e-SONET, kanye ne-DWDM.Ezinye izinkampani zenze amaswishi e-fiber-optic Ethernet anikeza izici ezihlukahlukene ukuze kuqinisekiswe ikhwalithi yesevisi engcono kakhulu (njenge ukuhlungwa kwephakethe kanye nokuphathwa kokuminyana).Lo mkhiqizo ungase udinge lobu buchwepheshe nezici ezibalulekile ezilandelayo: ukwethembeka okuphezulu, ukuminyana kwembobo okuphezulu, kanye neziqinisekiso zekhwalithi yesevisi.I-Fiber-optic Ethernet iyonga futhi isebenza kahle kakhulu kunokunye ukuxhumana kwe-broadband, kodwa kuze kube manje isetshenziswe kuphela ezakhiweni zamahhovisi noma ezakhiweni lapho ifayibha isivele ibekiweInani lesu lale ndlela entsha yokusebenzisa i-Ethernet alikhawulelwe 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 eziyisisekelo. Ngaphezu kwalokho, ngenxa yokuthi iseyi-LAN ngokwemvelo, ingasetshenziswa ukusiza abahlinzeki besevisi ukuphatha ukuxhumana phakathi kwama-LAN ezinkampani nama-LAN ezinkampani namanye amanethiwekhi.
Isikimu sokufinyelela samaswishi e-fiber-optic Ethernet
Njengoba kuboniswe emfanekisweni, idivayisi eyinhloko yenethiwekhi iwumshini wefayibha obekwe ekamelweni leselula noma igumbi lekhompyutha yokwakha.I-fiber switch ixhunywe kumzila we-inthanethi onqenqemeni noma ukushintsha kweqoqo ngenani elingu-1000 M/100 M nge-fiber optical ukuze kusetshenziswe ukufinyelela kwenethiwekhi yeselula ku-inthanethi.
Iswishi ye-fiber optical ixhunywe neyunithi yenethiwekhi yokubona ebekwe ekhaya lomsebenzisi noma ikhadi le-Ethernet elakhelwe ngaphakathi nge-duplex 100M isilinganiso nge-optical fibre kanye nemodi yokukhomba-kuya-iphuzu.Ukuxhumana phakathi kwe-optical fibre switch kanye neyunithi yenethiwekhi ye-optical ngokusebenzisa i-fiber optical high-speed ukufinyelela ku-inthanethi kuyimodi 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;ukususa amaswishi aphansi, igumbi leseli kuphela eliyindawo esebenzayo, enciphisa izindleko zokulungisa; I-single switch node ekamelweni lamaseli ingathuthukisa ngempumelelo ukusetshenziswa kwe-switch port.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.
