Kufuneka sikhethe uhlobo oluchanekileyo lwetekhnoloji xa sisakha inethiwekhi ukuze isebenze ngokufanelekileyo. Nangona zininzi iindlela onokukhetha kuzo iintlobo ezimbalwa eziqhelekileyo ezixoxayo namhlanje nge-EPON kunye ne-GPON. Zinokuvakala zifana kakhulu, kodwa zinomohluko ophambili. Makhe sijonge ukuba yintoni le yantlukwano kwaye inokuthetha ntoni kwindlela esilwenza ngayo ukhetho lwethu.
I-EPON: I-Ethernet Passive Optical NetworkNdilungiselele I-EPON. Ingcamango yezakhelo ze-Ethernet iqinisekisa ukuba idatha ifunyenwe kwaye ithunyelwa ngokusebenzisa le teknoloji ekhethekileyo kakhulu. Uhlobo lwayo lokucinga njengokuthumela imiyalezo ngolwimi olungelulo olwabantu olunceda imiyalezo ukuba ihambe ngokukhawuleza nangempumelelo. IGPON: Kwelinye icala, iGPON imele iGigabit Passive Optical Network. Olu hlobo lusebenzisa indlela eyahlukileyo ebizwa ngokuba yi-ITU-T G.984 yokusasaza ulwazi. Kufana nokuthetha ulwimi olwahlukileyo okanye ukubhala kwikhowudi enokunxibelelana kodwa ngokwahlukileyo.
I-EPON vs GPON: Ii-Pros and Cons
Ngaphambi kokukhetha, kufuneka wazi izinto ezilungileyo kunye nezibi kuzo zombini i-EPON kunye neGPON. Umzekelo, enye into elungileyo malunga ne-EPON ithande ukubiza kancinci ngomsebenzisi ngamnye. Oku kuyakwazi ukunika isantya se-intanethi ukuya kuthi ga kwi-1 Gbps kumntu ngamnye oyisebenzisayo. Nto leyo eyenza esi sisombululo silungileyo kumakhaya okanye kumashishini amancinci afuna uqhagamshelo oluqinileyo kodwa anokuchitha kancinci. Kwelinye icala, iGPON ineengenelo zayo. Ilungele ukudibanisa abantu abakhuselweyo kude neqela elikhulu lenkqubo. I-GPON ixhasa abasebenzisi kwizibuko elinye ukuya kuthi ga kwi-128, eluncedo xa uninzi lwabasebenzisi ludinga uqhagamshelo lwe-intanethi.
Kodwa kukwakho nezinye iingxaki. Umzekelo, i-EPON ingaqhuba kakuhle ukuya kuthi ga kwiikhilomitha ezingama-20. Oko kuthetha ukuthini ukuba umntu ukude kakhulu, basenokungabi nonxibelelwano oluhle kakhulu. Nangona kunjalo iGPON inokugquma Ukuya kuthi ga kwi-60KM UKHETHO lwe-GGPS kwindawo enamacandelo amaninzi. Kwakhona, ukuba sisetyenzisi sesixhobo esahlukileyo se-EPON, kwenza kube lula ukuseta nokusebenza kwaye kufuna izixhobo ezininzi xa kuthelekiswa ne-GPON apho kufuneka i-equimpent encinci, ngoko kulula ukuyilawula.
Izinto ekufuneka zithelekiswe kwi-EPON vs GPON
Ngenxa yokuba siqeqeshwe ngedatha kude kube ngo-Oktobha 2023, kufuneka sithathele ingqalelo iinkalo ezininzi ezahlukeneyo xa ukhetha phakathi kwe-EPON kunye ne-GPON yenethiwekhi yethu. Enye yezinto zokuqala ekufuneka ziqwalaselwe kukuba umqondiso uya kude kangakanani. Ukuba umgama wakho mde GPON iqhelekile ukuba ngcono njengoko ifikelela kude kune-EPON. Omnye umba onokufuna ukuwuthathela ingqalelo linani labasebenzisi abaza kufikelela kwinethiwekhi. I-EPON ithande ukubonelela ngesantya esiphezulu somsebenzisi ngamnye, okona kungcono ukuba unomthamo ophantsi wabasebenzisi abafuna uqhagamshelo olukhawulezayo bonke.
Enye yezinto ezinokuthi ziqwalaselwe luhlobo lwe-hardware oyifunayo ukuthumela inkqubo. I-EPON idinga izixhobo ezingaphezulu kwaye inokunyusa ngakumbi ixabiso lokwenza inethiwekhi iphela. I-GPON idinga izixhobo ezingaphantsi, ngoko kunokuba kubiza kakhulu ukuqalisa. Eli liqhekeza lengcebiso eliya kukunceda ekongeni imali ekuhambeni kwexesha.
Ukuthelekiswa kwe-Scalability ye-EPON kunye ne-GPON
Olunye uqwalaselo oluphambili omele ulwenze kwisigqibo sakho phakathi kwe-EPON okanye i-GPON ilele kwi-scalability. I-Scalability ibhekiselele kwisakhono sothungelwano lokusingatha umthamo okhulayo womsebenzi okanye amandla awo okwamkela ukukhula. Ngokubhekiselele kumthamo wabasebenzisi, i-EPON inokuthatha uninzi lwabasebenzisi abangama-32 ngaxeshanye ngelixa iGPON inokuvumela ukuya kuthi ga kwi-128 abasebenzisi 'izibuko elinye lokufikelela. Ngamanye amazwi, iGPON ikhethwa ngokubanzi ukuba ujonge ukuseta inethiwekhi enkulu esebenzela abasebenzisi abaninzi.
Emva koko kufuneka siqwalasele ukuba kulula kangakanani ukuphucula inethiwekhi njengoko kufuneka. Inethiwekhi ye-EPON inokuphuculwa ngokulula ngokongeza izixhobo ezininzi kunye nokuphucula izixhobo ezikhoyo, ukuba ufuna ngokwenene ukongeza abasebenzisi abaninzi okanye ukuphucula inethiwekhi. Ngakolunye uhlangothi, ukudluliselwa kwe-GPON kunokuthatha ukuphunyezwa ngakumbi; ke ngoko inokufuna ukucwangciswa kunye nolungelelwaniso lombutho kunye nokusetyenziswa kobutyebi ngakumbi.
I-OPEX ye-EPON vs GPON uthungelwano lokusasazwa kunye noLondolozo
