Itekhnoloji ye-Fiber-optic Ethernet kukuhlangana kunye nophuhliso lwetekhnoloji ezimbini eziphambili zonxibelelwano, ezizezi, i-Ethernet kunye nenethiwekhi ye-optical. Igxininisa kwiingenelo ze-Ethernet kunye neenethiwekhi zamehlo, njengezicelo eziqhelekileyo ze-Ethernet, ixabiso eliphantsi, uthungelwano oluguquguqukayo, ulawulo olulula, oluphezulu. ukuthembeka kunye nomthamo omkhulu wothungelwano lwe-optical network.
Isantya esiphezulu kunye nomthamo omkhulu we-Ethernet ye-optical isusa i-bottleneck ye-bandwidth ekhoyo phakathi kwe-LAN kunye ne-WAN, i-witcher iya kuba yinto enye yenethiwekhi yokuguqula ilizwi, idatha kunye nevidiyo kwixesha elizayo.Imveliso ye-Fiber-optic Ethernet inokusebenzisa iinkonzo zonxibelelwano ze-WAN usebenzisa Iifomathi zepakethe ze-Ethernet zisebenzisa izixhobo ze-Ethernet.Okwangoku, i-fiber-optic Ethernet inokufezekisa isantya se-Ethernet esiqhelekileyo se-10Mbps, i-100Mbps kunye ne-1Gbps.
Izixhobo ze-Fiber-optic Ethernet zisekelwe kwi-Layer 2 LAN switch, i-Layer 3 LAN switch, izixhobo ze-SONET, kunye ne-DWDM.Ezinye iinkampani ziye zaphuhlisa i-fiber-optic Ethernet iinguqu ezinikezela ngeempawu ezahlukeneyo ukuqinisekisa umgangatho ophezulu wenkonzo (ezifana ne ukuhlelwa kwepakethi kunye nolawulo lokuxinana).Le mveliso inokufuna obu buchwepheshe bulandelayo kunye neempawu: ukuthembeka okuphezulu, ukuxinana kwe-port ephezulu, kunye nomgangatho weziqinisekiso zenkonzo.I-Fiber-optic Ethernet inoqoqosho kwaye isebenza kakuhle kunolunye uxhulumaniso lwe-broadband, kodwa okwangoku isetyenziswe kuphela kwizakhiwo zeofisi okanye kwizakhiwo apho ifayibha sele ibekiwe.Ingasetyenziselwa zombini ukufikelela kuthungelwano kunye nothungelwano lwe-backbone yendawo kwinethiwekhi yomnikezeli wenkonzo.Inokusetyenziswa kuphela kwiNqanaba 2 okanye njengendlela esebenzayo yokuphumeza iinkonzo ze-Layer 3.Iyakwazi ukuxhasa i-IP, i-IPX kunye nezinye iiprotocol zendabuko.Ukongezelela, kuba kuseyi-LAN kwindalo, ingasetyenziselwa ukunceda ababoneleli ngenkonzo ukulawula uxhulumaniso phakathi kwee-LAN zenkampani kunye nee-LAN zenkampani kunye namanye amanethiwekhi.
Iskimu sokufikelela kwiiswitshi ze-fiber-optic Ethernet
Njengoko kubonisiwe kumzobo, isixhobo esisisiseko senethiwekhi sisitshixo sefayibha esibekwe kwigumbi leseli okanye kwigumbi lokwakha ikhompyuter.I-fiber switch ixhunyiwe kwi-router edge ye-Intanethi okanye ukutshintshwa kokuqokelela kwizinga le-1000 M / 100 M nge-fiber optical ukuphumeza ukufikelela kwenethiwekhi yeselula kwi-Intanethi.
Ukutshintshwa kwe-fiber optical ixhunyiwe kunye neyunithi yenethiwekhi ye-optical efakwe kwikhaya lomsebenzisi okanye i-fiber optical eyakhelwe kwi-Ethernet ikhadi kwi-duplex 100M izinga ngokusebenzisa i-fiber optical kunye ne-point-to-point mode.Ukudibanisa phakathi kokutshintsha kwe-fiber optical kunye neyunithi yenethiwekhi ye-optical ngokusebenzisa i-fiber optical high-speed access to Internet is a single-fiber two-way mode.
Xa kuthelekiswa ne-5 ekhoyo - i-line - esekelwe kwi-broadband ye-LAN yokufikelela kwi-broadband, esi sikimu sokufikelela sinezi zinto zilandelayo ezibalaseleyo:Isisombululo se-FTTH esisezantsi;Ukuphelisa ukutshintshwa komgangatho, kuphela igumbi leseli yindawo esebenzayo, ukunciphisa iindleko zokugcinwa; I-node enye yokutshintsha kwigumbi leseli inokuphucula ngokufanelekileyo ukusetyenziswa kwe-port port.I-bandwidth ephezulu kakhulu, ngamaxesha angama-100 ADSL;Umgama omde wokufikelela;Inethiwekhi yokubeka iliso ekude kwimodyuli nganye yeefoto zombane.Ngokwahlulwa kwezibuko kunye nemisebenzi yolawulo lwe-bandwidth;I-Web Server enamandla yolawulo lwenethiwekhi function.This iskimu ifaneleke ngokukodwa kubasebenzisi beendawo zokuhlala eziqhelekileyo, izakhiwo zeofisi, izikolo kunye nezibhedlele, kunye nabaqhubi be-telecom bendabuko kunye nabaqhubi benethiwekhi yabahlali.
Isishwankathelo:
Ngokujonga intsingiselo yophuhliso jikelele, ukusetyenziswa kwefiber optical kuthungelwano lofikelelo kufuneka kuqala endaweni yentambo ye-feeder kunye nefiber feeder, kwaye emva koko kuqhubeke nomsebenzisi.Nangona kunjalo, iindleko zinyuka kwaye ziphezulu, okwangoku, i-fiber optical idla ngokufikelela kuphela kwibhokisi yokuhanjiswa kwendlela, oko kukuthi indawo yokufikelela kwishishini (SAP).
Eyona njongo yenethiwekhi yokufikelela kwifiber ecocekileyo kukukhuthaza i-fiber optical kubasebenzisi beendawo zokuhlala.Okwangoku, akukho ngqiqweni ukuzisa i-fiber optical ekhaya, kuba ixabiso le-fiber optical lisabiza kakhulu, ngoko ke ukusetyenziswa kwe-fiber optical Ethernet ukufikelela kuyisisombululo esiphantsi se-FTTH.
