Kutheni ufake iSatellite phezu kweGPON
ISathelayithi yoSasazo oluNgqo (i-DBS) kunye neNgqo kwiKhaya (DTH) yeyona ndlela idumileyo yokonwabela iTV yesathelayithi kwihlabathi jikelele. Ukwenza oko, i-antenna yesathelayithi, intambo ye-coaxial, i-splitter okanye i-multi-switcher kunye ne-satellite receiver iyimfuneko. Nangona kunjalo, ukufakela i-eriyali yesathelayithi kunokuba nzima kubabhalisi abahlala ezindlini. I-SMATV (i-satellite master antenna TV) sisisombululo esihle kubantu abahlala kwisakhiwo okanye kuluntu ukuba babelane ngesitya esinye se-satellite kunye ne-antenna ye-TV yomhlaba. Ngentambo yefiber, i-SMATV RF isignali inokuhanjiswa kwi-20Km kude okanye isasazwe kumagumbi angama-32 ngokuthe ngqo, ukuya kuma-320 okanye ama-3200 okanye amagumbi angama-32000 nge-GWA3530 fiber optic amplifier.
Ngaba oku kuthetha ukuba i-MSO yesathelayithi okanye umdibanisi wenkqubo yesathelayithi kufuneka afakele intambo yefiber yabucala kumrhumi ngamnye? Ewe kunjalo, sidinga ifayibha kubo bonke ababhalisile ukuba sinako, kodwa akuyomfuneko ukuba kukho i-GPON fiber ekhaya. Enyanisweni, i-tt yindlela ekhawulezayo yokuba sisebenzise i-GPON fiber ephethwe yiTelecom MSO. I-Intanethi yenye yezona mfuno zibalulekileyo kusapho ngalunye. I-GPON (1490nm/1310nm) okanye i-XGPON (1577nm/1270nm) ziitekhnoloji ezithandwayo ezisekelwe kwifayibha ukuya ekhaya: i-terminal yomgca we-optical line (OLT), i-1x32 okanye i-1x64 okanye i-1x128 PLC i-fiber splitter, ngaphantsi kwe-20Km umgama we-fiber network kunye ne-o (ONU) kwintsapho, i-topology yenethiwekhi efanayo esiyifunayo. Isiginali yesathelayithi ithwalwa kwifestile ye-1550nm ebonakalayo, sifaka nje i-OLT ifayibha kwi-GWA3530 1550nm i-OLT ye-optical amplifier port, ungenzi nto kwi-PLC splitter kunye ne-fiber cable. Kwikhaya ngalinye lomrhumi sisebenzisa i-SC/UPC enye ukuya kwi-SC/UPC i-fiber jumper kunye ne-optical LNB ukuya kwi-ONU, emva koko iRF yesathelayithi kumsebenzi ngamnye wekhaya unokwenziwa ngemizuzu emi-5.
Ngamafutshane, kungafuneka sifake ifayibha kwikhaya ngalinye leTV yesathelayithi kuluntu olunamakhulu ababhalisile. Kwidolophu yamawaka ababhalisi okanye kwisixeko samakhulu amawaka ababhalisi, ukufaka iTV yesathelayithi phezu kwe-GPON fiber kuya kuba lishishini elisebenzayo kunye nenzuzo kubo bobabini umqhubi wesatellite kunye nomqhubi we-GPON.
Ngaba iTelecom MSO izimisele ukwabelana ngeGPON fiber? Kunokuba nzima kwaye kunokuba lula. I-GPON ine-2.5Gbps phantsi kwemilambo ukuya kwi-32 okanye i-64 okanye i-128 yababhalisi apho i-IPTV okanye ividiyo ye-OTT idla ininzi ye-bandwidth. I-OTT efana neNetflix njl. njl Umabonwakude wesathelayithi unomtsalane ngakumbi ngenxa yezinto ezikuwo. Ukuba umqhubi we-satellite uzimisele ukwabelana ngengeniso yenyanga kunye nomqhubi we-GPON, umqhubi we-satellite unokuba ne-30K, okanye i-300K yababhalisi abongezelelweyo ngexesha elifutshane (aba babhalisi abanako ukufaka izitya zesathelayithi); kunye nomsebenzisi we-GPON unokuba nenkonzo yokongeza ixabiso kubabhalisi babo kunye nokuphucula umgangatho wenkonzo ye-intanethi.
