EPON vs GPON: Yeyiphi Indlela Elandelayo Lokuqala Lokhu? Ngaphandle Kwesicelo Sakho?

Kufuneka sithola indlela elandelayo lokuhlola umbhalo wakho ukuthi libe ngaphandle kokuba kuhlola ngokuphumeleyo. Ngokushesha kukhonjwa iimeko ezininzi, zintliziyo ezimbini ezinethetha phambi kokuthi EPON kunye no-GPON. Izinkinga zakhe zikwazi ukubonisa ngokuphambili, kodwa zihlukile izindlela zakho. Ukuba bafune ukuhlola ngeendlela ezidingekayo, uzogcina ukubona zonke izinkinga ezidingekayo.

EPON: Ethernet Passive Optical NetworkNgenisa Ndiye Ukwenza EPON. Isimo sokuqala sokuthi iiframe zeEthernet zisihlela ukuthi idatha lizibalekiswa kwaye lizisendwe ngokulandelwa kwiteknoloji esidingekayo. Ngokushesha, lokhu kufuneka ungene ngesicatshulwa esingaziyo umntu wakwesobizo olungazange uhlale okanye uzale amandla adata ngokupheleleyo nokugcina. GPON: Ngaparaphu, GPON ifanelekile kwiGigabit Passive Optical Network. Leli ngeniso lusetshenziswa ngokwesiphi imethode elichaza ITU-T G.984 yokuthuthukisa idatha. Lokhu kufuneka ungene ngesiliso esingaziyo umntu wakwesobizo olungazange uhlale okanye uzale amandla adata ngokupheleleyo kodwa ngokushesha.

EPON vs GPON: Amahleli namagunya

Ngemva kokuthi uzikhetha, kufunekuhle ukwazi amagcinyelo namaphathiso wabanye nge-EPON kunye ne-GPON. Ngokubanzi, into ephakamisekileyo ngoku kwi-EPON yinto okungcono ngokugcino lapho akudinga iindlela ezifanayo. Ukugcina lokuvula imali iphambili kweziciko esingazange zihlabelele khona. Lento lingayithola isandla sentsha se-internethi usuka ku-1 Gbps ngalendaweni olusetyenziswayo. Okungakho kwenziwa ukulandelana nokuba le nto ingaqondela kakhulu kumalenti abantu abaningi abaningqaleke umoya omkhulu kodwa akudinga ukuphuma imali engaphezolo. Ngokwesobukhule, u-GPON ungenziwa amagcinnyelo ad basebenza. Yintoni elidingayo yokubungaza abantu abangaphandle komphakathi wesistimu sokudala. U-GPON uyasiza abantu ngokusebenzisa indawo yesikhati sesi-128, okuningi lokhu oluhlaba abantu abaningi abaningqaleke umoya.

Kodwa kunezinyathelo ezifana ngenxa lokho. EPON, ngokubanzi, akwazi ukusebenza khona ngaphandle komi-20. Okuthi yindlela yini yile yiyo ukuze umntu ophandle kakhulu awaphele amandla okanye apho aqale ukuxhasa. NGOKUHLAWULHA KU GPON AKWAZI UKUSENGELA NGAPHANDLE KOMI-60 CHOICE YEGGPS YAMAKHEHLO WESIXHASA. Futhi, ukuba kube nequimenthu entsha yokusetupa kwi-EPON, uyahlala kuhlu kakhulu ukusetupela nokusebenzela futhi kufuneka kunesithombe esingakade sishintiwe ngu-GPON apho kunesithombe esingakade sishintiwe, ngoko ke kungcono ukusetyenziswa.

Izicatshulwa Zokubonisa Nge-EPON vs GPON

Ngokuqinisekileyo ukuba siyafika emva kokusetyenziswa kwezidluko ngomdala ngoNkulu 2023, sifuneka sikwenzele ngezinye iindlela ezidingeki lokusebenzisa EPON kunye noGPON kwiseveni sethu. Ngokulandelayo, isimo esizodingekayo sengqeleni yokuthi le ndaba ayiphi akuyenza. Ukuba umgama wakho ubhali, GPON usenokubonisa ngokuthi uyayibhidisi phakathi kweEPON. Isimo esingaphezulu esifuna ukubophelela nokuba yeyiphi amagosa oza kusetyenziswa kwiseveni. EPON usebenzisa umoya ofanayo ngaphandle kwamagosa, okungcono ukuba ungenxa yamatyolo amangci aziphumeleyo abaningqi ukuba zazithathe imigomo eliphambili.

Isimo esingaphezulu esifuna ukubophelela nokuba yeyiphi amasiko asetyenziswa ukusetshenziswa kwalendlela. EPON ifanele amaxwebhu okubhali kunye nokuba kube ngokushesha ukusetshenziswa kwalendlela. GPON ayifanele amaxwebhu okubhali, futhi lufuneka libe ngokusetyenziswa. Lolu hlobo lwemibuzo lwakho luchaza ukuba uzisetshenziswa imali ngokukhona.

Ukubophelela kweEPON kunye noGPON

Ukuphinda ukusondeza okuvunyelwe kwi-decision yakho phakathi kwe-EPON noma GPON iyaphakamisa kwi-scalability. Ukubuyiselwa ifanele ku-referencing ngokuba yintlizyo yokuba yinkqubo yokusebenziswa ukwenza imisebenzi ephakamisayo okukhulu noma ukuba ayiqondisiwe ukwenza ukubuya. Ngezinye izinto, i-EPON inakumisa 32 abasebenzisi ngalwesixhenxe xa i-GPON ingayithola 128 abasebenzisi′ umthombo omkhulu owenziwe. Ngokulandelayo, i-GPON isetshenziswa ngokugcinwa xa ufuna ukusetshenziswa ukuthi uhlale kwindawo elikhulu lokusebenza kuneene abasebenzisi.

Kufuneka siphinde sihlalele ukuba ngokuqinisekile ukusetshenziswa kwenzelelo lento yini. Into yento ye-EPON iyasetshenziswa ngokuqinisekile ngokuyibuyelela amaxwebhu okanye ukuyihlanganisa amaxwebhu aqondile, xa ufuna ngokuhlu ukuyibuyelela abasebenzisi okanye ukusetshenziswa kwenzelelo. Ngokwesobukele, into yonto ye-GPON iyasetyenziswa ngokuba kufunekako ukubuyekeza nokuhlola kwezindaba zomsebenzi kunye neziqhutywa ezininzi.
