Yintoni i-OLT kuthungelwano lwefiber?

AmaTides OLT yiThink Tides — yonwabele! I-Optical Line Terminal (OLT) yenye yezona zinto zibalulekileyo zothungelwano lwefiber. Yinto esincedayo ekusebenziseni i-intanethi ngokukhawuleza nangempumelelo. Kule ngcaciso ilandelayo siza kucacisa ukuba yintoni eyenziwa yi-OLT, isinceda njani ekwenzeni unxibelelwano lukhawuleze okokugqibela, yintoni imfuneko yalo kulowo usebenzisa i-fiber internet. Ukongeza, siya kuhlalutya amacandelo ayo kunye nendlela asebenzisana ngayo ukuze asinike iinkonzo esizisebenzisayo. 

Utshintsho kuShishino loMnatha weFayibha :Icandelo loku-1: I-OLT njengeNtliziyo yeNethiwekhi 

Iisistim zeFiber ziqulathe iSitena esiKhethekileyo somgca (OLT) njengeyunithi esembindini. Ukutshintsha kwemodem kunceda ngokunika iwebhu yasekhaya kunye neyorhwebo, iTV, kunye nolawulo lweefowuni. Cinga nge-OLT njengeyona ndawo iphambili ukuba yonke into idibana nayo. Ngokuqhelekileyo, i-OLT ithunyelwa kwindawo yokuphela kwentloko (indawo ye-ISP). Ukusuka apho ithumela kwaye ifumane idatha ngokusebenzisa izixhobo ezikhethekileyo ezaziwa ngokuba zii-terminal optical organise (ONTs). Ezi ONTs zinokufunyanwa kumakhaya nakumashishini ajongana nabathengi kulungiselelo lwefiber. 

Yenza ntoni i-OLT? 

I-OLT isebenza kanye njengombindi wolawulo womnatha wothungelwano. Iphatha lonke ulwazi olusondelayo kunye nolusebenzayo ukuya nokusuka kwi-ISP kunye nee-ONT. Phakathi kwenkqubela phambili engenakucingelwa i-OLT esetyenziswayo ibizwa ngokuba yi-wavelength division multiplexing, eyaziwa ngokuba yi-WDM. I-TDM ixhobisa imiqondiso emininzi eyahlukeneyo ukuba bonke bahambe ngentambo enye yefiber optic ngaxeshanye. Cinga ngomthwalo omde wendlela apho inani leemoto zinokuhamba ngokwembono ngaphandle kwe-interferometer nabanye abaninzi. Esi siguquli se-gpon sokukwazi ukuthumela kunye nokwamkela izixa ezahlukeneyo zolwazi ngokukhawuleza kakhulu kwifayibha enkulu kuthetha ukuba iOLT iyakwazi ukusasaza imithamo emikhulu yedatha ngokukhawuleza okukodwa. Ngapha koko, sesona sizathu sikhulu sezizathu zefayibha ezihambisa iwebhu ngokukhawuleza kunezinye iintlobo zonxulumano lwewebhu olufana neDSL okanye iCable. 

Yeyiphi indima edlalwe ziiOLT kuNxibelelwano oluKhawulezayo? 

I-OLT -I-OLTs idlala indima ebalulekileyo ekuqinisekiseni iinkqubo zefayibha zihambisa isantya esiphezulu kakhulu sewebhu xa kuthelekiswa nezinye iintlobo zemibutho yewebhu. Ulwazi kwiinkqubo zefiber ngohambo njengokukhanya kwiintambo ezibhityileyo zeglasi, okanye zeplastiki. Isantya sokukhanya sibaleka kakhulu kunayo nayiphi na iflegi yombane esiya kuyisebenzisa kwezinye iintlobo zemibutho. Ngenxa yoko ulwazi lunokusasazwa ngokukhawuleza nangobuchule. Yiyo loo nto i-fiber web ikunika amandla okukhuphela imifanekiso eshukumayo, ulonwabo kunye nezinye iirekhodi ezinkulu ezikhawulezayo kunezinye iintlobo zenzuzo yewebhu. Le ma5608t ivumela abathengi ukuba babongoze yonke into yenziwe ngokukhawuleza nangaphantsi kwemfuneko. 

Iinxalenye zeOLT 

Izinto ezininzi zenza i-OLT, zonke zisebenza esona sizathu sibalulekileyo ngaphakathi kolungelelwaniso olukhulu lolwazi lwangaphakathi kwifiber. Inxalenye yotyando ngokwenene likhadi lomgca wokukhanya. Eli khadi litshintsha iisignali zombane ezisuka kwi-ISP zibe ziimpawu zokukhanya ezithi canh texture. Ukutshintsha ukuthungwa yinxalenye ye-OLT eyenza umehluko kwingcaciso yekhosi kunye nokulawula umlambo wayo ukusuka kwi-OLT ukuya kwii-ONT ezahlukeneyo. Ekwandiseni, i-OLT iqulethe ezinye iindawo ezisisiseko ezifana nezixhobo zokulawula, i-fan yokupholisa, kunye neemodyuli zolawulo ezinikezela ngoncedo zigcina ukusebenza okuqhelekileyo kunye nokusebenza kakuhle kwe-OLT. 

Konke okufuneka ukwazi malunga ne-OLTs 

Ke ukuba ungumphathi olungelelanisayo, kusisiseko ngokwenene ukwazi ukuba isebenza njani i-OLT. Ukuqaphela i-OLT kuya kukuthatha indlela ende ekongameleni ulungiselelo lwakho lwefiber ngempumelelo. Yila i-OLT ngokwakho Yazi imiba yayo, Kwithuba lokuba nayiphi na, Chonga ilungele abo bane-fiber web. Umzekelo, ukuba unezantya zewebhu eziphakathi, ingayingxaki kwiOLT. Ukuqonda i-OLT kuxhobisa unxibelelwano olusebenzayo kunye ne-ISP, oluza kwisigqibo esikhawulezayo kunye nokuzimisela kwemiba.
