Njengoba i-inthanethi idlangile kule planethi, ukusakazwa kwevidiyo okudingeka kakhulu kuthatha ingxenye enkulu emakethe yokuzijabulisa ye-TV yomuntu siqu. I-TV ebukhoma evela kumasathelayithi isadlala indima ebalulekile kumabonakude womndeni noma emakethe yokuzijabulisa yephathi ye-TV. I-Satellite MSOs kufanele inikeze okuqukethwe okuhle kakhulu kwe-TV ukuheha nokugcina ababhalisile. Ngokungafani nokuqukethwe kwe-FTA, ama-MSO wesathelayithi abusayo anokuqukethwe kwe-TV ebethelwe nge-CA. I-MSO yesathelayithi ehlukile inokuqukethwe kwayo okufakiwe ukuze iqhudelane emakethe. Ababhalisile bangase bathande ukubuka isathelayithi engaphezu kweyodwa lapho isathelayithi entsha ingase inikeze okuqukethwe okuhlukile okukhangayo.
Ukufakwa kwesitsha sokuhlala kwendabuko kunzima kakhulu ngekhaya elilodwa ukukhokhela izitsha ezihlala eziningi. Kodwa-ke, i-fiber yomphakathi noma i-fiber yedolobha yenza kube lula kakhulu ukusabalalisa amasathelayithi amabili noma okuqukethwe kwamasathelayithi amane ezindlini eziningi. Ngakolunye uhlangothi, umnikazi wefayibha angaba nesevisi eyengeziwe enenani elikhulu ngokunikeza isevisi yokusabalalisa ngesathelayithi. Umuntu ngamunye obhalisele i-FTTH angakhetha isethelayithi A noma isathelayithi B noma kokubili okuqukethwe kwesathelayithi.
I-DirecTV ne-Dish, i-TataPlay ne-Airtel, i-Sky Mexico ne-Dish Mexico, i-Nilesat ne-Arabsat, njll., Imikhiqizo yefiber ye-TV yesathelayithi ye-Greatway Technology yenza lezi zinhlanganisela zesathelayithi zitholakale ekhaya elimbozwe ngefayibha.
Ku-MSO yesathelayithi enama-transponder angaphansi kwama-32, umdwebo ongenhla usebenza kumuntu ngamunye obhalisele i-FTTH ukuze ajabulele okuqukethwe okuhlezi okukodwa noma okubili.I-GLB3500M-2Ti-optical transmitter iguqula ama-LNB RF amawele amabili ukusuka kumasathelayithi amabili kanye ne-Terrestrial TV (174~700MHz) RF ibe yifayibha eyodwa engu-1550nm ophahleni olulodwa lwesakhiwo. Ukukhishwa okubonakalayo kwe-GLB3500M-2T kungashayela izemukeli ze-optical ezingama-32pcs ngokuqondile nge-PLC fiber splitter, lapho umuntuGLB2000Aisamukeli sokubona sinikeza noma yikuphi okuqukethwe kwamasathelayithi amabili namasignali e-Terr TV ku-STB eyodwa ne-TV efulethini elilodwa,I-GLB3500M-2R4-Kisamukeli sokubona sisekela imbobo ye-Terr TV eyodwa yama-multi-TV kanye nama-STB ahlala ama-4 endlini eyodwa, i-STB ngayinye ehlezi ingaba yisathelayithi A STB noma isathelayithi B STB. Uma inombolo yababhalisile ingaphezu kwamakhulu noma izinkulungwane emphakathini noma edolobheni, sizoba neamplifier eyodwa yokubona.GWA3530ngemuva kwe-GLB3500M-2T isidluliseli esibonakalayo.GWA3530i-optical amplifier ine-8 noma 16 noma 32 noma 64 port, imbobo ngayinye ingashayela 16 noma 32 noma 64 optical receiver. Ngamanye amazwi,GWA3530ingashayela izemukeli ze-optical ezingu-1024 noma izamukeli ze-optical ezingu-2048 noma izamukeli ze-optical ezingu-4096 ku-20Km fibre ibanga. Ngembobo yokufaka ye-OLT yokuzithandela,GWA3530ingafaka i-TV RF yesathelayithi phezu kwefayibha efanayo ye-GPON noma inethiwekhi ye-XGPON.
Izinzuzo zesathelayithi TV FTTH:
- Kuhlezi izitsha ezimbili zababhalisile abangu-32 noma izinkulungwane zababhalisile
- Ikhwalithi engcono yesignali yesathelayithi endaweni ngayinye yefayibha
- Itheminali ye-Fiber ifakwa kalula emizuzwini emi-5 ngokuklama "plug and play".
- Umamukeli ojwayelekile wesathelayithi ovela ku-Satellite A STB noma iSatellite B STB
Uma isathelayithi inama-transponder wesathelayithi angaphezu kuka-32, ibhendi ephansi nebhendi ephakeme (engaphansi kwethoni engu-22KHz) yethulwa e-Quattro LNB ukuze ihlangabezane nesamukeli esivamile sesathelayithi esingu-950MHz~2150MHz. Sincoma ukuthi ufake i-twin wideband LNBI-GWB104Gesitsheni sesathelayithi.I-GWB104GI-LNB inefrikhwensi engu-10.4GHz LO kanye nemiphumela emibili ye-RF enomkhawulokudonsa ongu-300MHz~2350MHz, okungukuthi, i-wideband Vertical RF ilingana ne-Vertical Lower (VL) kanye ne-Vertical Higher (VH) kuyilapho i-wideband Horizontal RF ilingana ne-Horizontal Lower (HL) kanye ne-Horizontal. Okuphakeme (HH). Njengoba i-wideband RF yomkhawulokudonsa ingaphezu komkhawulokudonsa we-RF wesamukeli sesathelayithi, sidinga i-chip ye-Digital Channel Satellite Switcher (dCSS) ukuze siguqule i-wideband RF ibe uhla lwesamukeli sesathelayithi. Ngaphezu kwalokho, umamukeli wesathelayithi kufanele asekele izinga elingavumelekile.
Emdwebeni ongenhla,I-GLB3500E-4Ti-optical transmitter iguqula ama-twin wideband LNB RFs abe yifayibha eyodwa engu-1550nm ophahleni olulodwa lwesakhiwo. I-optical output ye-GLB3500E-4T ingashayela ama-32pcs optical receiver ngokuqondile noma izinkulungwane zabamukeli be-optical nge-GWA3530 amplifier. Efulethini ngalinye, eyodwaI-GLB3500E-4WRi-optical receiver isekela izamukeli zesathelayithi ezingatholakali ezi-4 neyodwaI-GLB3500E-4WR2i-optical receiver isekela izamukeli eziyi-8 ezingasebenzi kahle zesathelayithi. Isamukeli ngasinye sesathelayithi singanquma konke okuqukethwe kwe-FTA kulawa masathelayithi amabili nokuqukethwe okubethelwe ngekhadi le-CA.
