Kungani ufake Isathelayithi phezu kwe-GPON
I-Direct Broadcasting Satellite (DBS) kanye ne-Direct to Home (DTH) kuyindlela edume kakhulu yokujabulela i-TV yesathelayithi emhlabeni wonke.Ukuze wenze lokhu, i-antenna yesathelayithi, intambo ye-coaxial, i-splitter noma i-multi-switcher kanye nesamukeli sesathelayithi ziyadingeka.Kodwa-ke, ukufakwa kwe-antenna yesathelayithi kungase kube nzima kubabhalisi abahlala ezindlini.I-SMATV (satellite master antenna TV) iyisixazululo esihle sokuthi abantu abahlala esakhiweni noma emphakathini babelane ngesitsha sesathelayithi esisodwa kanye nothi lwe-TV yasemhlabeni.Ngekhebula le-fiber, isignali ye-SMATV RF ingalethwa ku-20Km kude noma isatshalaliswe ezindlini ezingama-32 ngokuqondile, ezindlini ezingu-320 noma ezingu-3200 noma ezingu-32000 nge-GWA3530 fiber optic amplifier.
Ingabe lokhu kusho ukuthi i-MSO yesathelayithi noma isihlanganisi sesistimu yesathelayithi kufanele ifake intambo yefibre yangasese kubo bonke ababhalisile?Yebo, sidinga i-fiber kubo bonke ababhalisile uma sikwazi, kodwa akudingekile uma kukhona i-GPON fiber ekhaya kakade.Eqinisweni, i-tt iyindlela esheshayo ngathi yokusebenzisa i-GPON fiber ephethwe yi-Telecom MSO.I-inthanethi ingenye yezidingo ezibaluleke kakhulu kuwo wonke umndeni.I-GPON (1490nm/1310nm) noma i-XGPON (1577nm/1270nm) ubuchwepheshe obudumile obusekelwe kwifayibha eya ekhaya: i-one optical line terminal (OLT), 1x32 noma 1x64 noma 1x128 PLC fibre splitter, ngaphansi kuka-20Km ibanga le-fiber unit kanye o (ONU) emndenini, i-topology yenethiwekhi efanayo esiyidingayo.Isignali yesathelayithi ithwalwa efasiteleni le-1550nm optical, sivele sifake i-OLT fiber ku-GWA3530 1550nm optical amplifier OLT port, singenzi lutho ku-PLC splitter nentambo yefayibha.Ekhaya ngalinye lobhalisile sisebenzisa i-SC/UPC eyodwa ukuya ku-SC/UPC i-fiber jumper kanye ne-optical LNB kuya ku-ONU, bese kuthi i-RF yesathelayithi yomsebenzi ngamunye wasekhaya ingenziwa ngemizuzu emi-5.
Kafushane, kungase kudingeke ukuthi sifake i-fiber ekhaya ngalinye le-TV yesathelayithi emphakathini onamakhulu ababhalisile.Edolobheni lezinkulungwane zababhalisile noma edolobheni lamakhulu ezinkulungwane zababhalisile, ukufaka i-TV yesathelayithi phezu kwe-GPON fiber kungaba ibhizinisi elisebenza kahle futhi elinenzuzo kubo bobabili opharetha besathelayithi kanye no-opharetha we-GPON.
Ingabe iTelecom MSO izimisele ukwabelana nge-GPON fiber?Kungaba nzima futhi kube lula.I-GPON inokusakaza okungu-2.5Gbps phansi kuya kwababhalisile abangu-32 noma abangu-64 noma abangu-128 lapho i-IPTV noma ividiyo ye-OTT idla khona iningi lomkhawulokudonsa.I-OTT efana neNetflix njll. ayikhokhi ngisho indibilishi ku-GPON MSO yendawo futhi kukhona ama-OTT amaningi ngaphandle kweNetflix.I-TV yesathelayithi ikhanga kakhulu ngenxa yokuqukethwe kwayo.Uma u-opharetha wesathelayithi ezimisele ukwabelana ngemali engenayo yenyanga no-opharetha we-GPON, u-opharetha wesathelayithi angaba nababhalisile abangu-30K, noma abangu-300K ngesikhathi esifushane (laba babhalisi abakwazi ukufaka izitsha zesathelayithi);kanye no-opharetha we-GPON bangaba nesevisi ye-value-added kubabhalisi babo futhi bathuthukise ikhwalithi yesevisi ye-inthanethi.
