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 zisekwe kwiLayer 2 LANiiswitshi, Uluhlu lwe-3 LANiiswitshi, izixhobo ze-SONET, kunye ne-DWDM.Ezinye iinkampani zenze i-fiber-optic Ethernetiiswitshiezibonelela ngeentlobo ngeentlobo zeempawu zokuqinisekisa olona mgangatho uphezulu wenkonzo (njengokuhlela ipakethe kunye nolawulo lokuxinana) Le mveliso inokufuna obu buchwepheshe bulandelayo kunye neempawu: ukuthembeka okuphezulu, ukuxinana kwezibuko eliphezulu, kunye nomgangatho weziqinisekiso zenkonzo.Ifayibha- I-optic Ethernet inoqoqosho kwaye isebenza kakuhle kunolunye uqhagamshelo lwebroadband, kodwa ukuza kuthi ga ngoku isetyenziswe kuphela kwizakhiwo zeofisi okanye kwizakhiwo apho ifayibha sele ibekiwe. kuthintelwe ukufikelela kancinci. 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 kwifiber-optic Ethernetiiswitshi
Njengoko kubonisiwe kumzobo, i-network core device yifibertshintshaibekwe kwigumbi leseli okanye kwigumbi lekhompyutha yokwakha. Ifibertshintshaiqhagamshelwe kumda we-Intanethiumzilaokanye yingqokelelatshintshakwireyithi ye-1000 M / 100 M ngokusebenzisa i-fiber optical ukuphumeza ukufikelela kwenethiwekhi yeselula kwi-Intanethi.
Ifiber opticaltshintshaidibaniswe neyunithi yenethiwekhi ye-optical ebekwe kwikhaya lomsebenzisi okanye ikhadi le-Ethernet elakhelwe ngaphakathi kwi-fiber fiber kwi-duplex ye-100M izinga nge-fiber optical kunye ne-point-to-point mode. Uqhagamshelwano phakathi kwefiber opticaltshintshakunye 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; umgangatho wokuphelisaiiswitshi, ligumbi leseli kuphela eliyindawo esebenzayo, ecutha iindleko zokulondolozwa;tshintshaindawo yeseli kwigumbi leseli inokuphucula ngokufanelekileyo ukusetyenziswa kwetshintshaizibuko. I-bandwidth ephezulu kakhulu, ngamaxesha angama-100 ADSL; Umgama omde wokufikelela; Inethiwekhi yokubeka iliso ekude kwimodyuli nganye yombane wezibuko. 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.
