Nge-intanethi ekhoyo kule planethi, ukusasazwa kwevidiyo efunwayo kuthatha isabelo esikhulu kwimakethi yokuzonwabisa yeTV. I-TV ephilayo evela kwisathelayithi isadlala indima ebalulekileyo kumabonakude wosapho okanye kwimarike yolonwabo yeTV. IiSatellite MSOs kufuneka zibonelele ngemixholo yeTV ebalaseleyo ukutsala kunye nokugcina ababhalisile. Ngokungafaniyo nemixholo ye-FTA, ii-MSO zesathelayithi ezilawulayo zine-CA imixholo ye-TV efihliweyo. I-MSO yesathelayithi eyahlukileyo inezinto zayo ezifakiweyo zokukhuphisana kwimarike. Ababhalisi bangathanda ukubukela ngaphezulu kwesathelayithi enye xa isathelayithi entsha inokubonelela ngezinto ezahlukeneyo ezinomtsalane.
Ufakelo lwesitya semveli lunzima kakhulu ukuba ikhaya elinye likwazi ukuthenga izitya ezininzi. Nangona kunjalo, ifayibha yoluntu okanye ifayibha yesixeko yenza kube lula kakhulu ukusasaza iisathelayithi ezimbini okanye iziqulatho ezine zesathelayithi kumakhaya amaninzi. Kwelinye icala, umnini wefayibha unokuba nenkonzo eyongeziweyo ngexabiso elingakumbi ngokunikezela ngenkonzo yokusasaza ngesathelayithi. Umxhasi ngamnye we-FTTH angakhetha isathelayithi A okanye isathelayithi B okanye zombini imixholo yesathelayithi.
I-DirecTV kunye neDish, i-TataPlay kunye ne-Airtel, i-Sky Mexico kunye ne-Dish Mexico, i-Nilesat kunye ne-Arabsat, njl., i-Greatway Technology yeemveliso ze-fiber ze-TV ze-satellite zenza le midibaniso ye-satellite ifumaneke kwikhaya eligqunywe yifiber.
Kwisathelayithi ye-MSO engaphantsi kwe-32 transponders, umzobo ongentla usebenzela umrhumi ngamnye we-FTTH ukonwabela ukuhlala omnye okanye imixholo emibini ehleliyo.GLB3500M-2Ti-optical transmitter iguqula amawele e-LNB RFs ukusuka kwiisathelayithi ezimbini kunye neTerrestrial TV (174~700MHz) iRF ibe yifayibha enye ye-1550nm kuphahla lwesakhiwo esinye. Imveliso ye-Optical ye-GLB3500M-2T inokuqhuba i-32pcs i-optical receivers ngqo nge-PLC fiber splitter, apho enyeGLB2000Aumamkeli obonayo ubonelela ngayo nayiphi na imixholo yesathelayithi ezimbini kunye neempawu zeTerr TV kwi-STB enye kunye nomabonwakude kwigumbi elinye,GLB3500M-2R4-KUmamkeli obonakalayo uxhasa izibuko le-Terr TV enye yee-TV ezininzi kunye nee-STB ezi-4 zokuhlala kwigumbi elinye, i-STB nganye ehleliyo inokuba yi-satellite A STB okanye isathelayithi B STB. Ukuba inombolo yomrhumi ingaphezulu kwamakhulu okanye amawaka kuluntu okanye esixekweni, siya kuba neamplifier enye.GWA3530emva kwe-GLB3500M-2T i-optical transmitter.GWA3530iamplifier optical has 8 okanye 16 okanye 32 okanye 64 port, izibuko ngalinye unako ukuqhuba 16 okanye 32 okanye 64 abamkeli optical. Ngamanye amazwi,GWA3530inokuqhuba i-1024 i-optical receivers okanye i-2048 i-optical receivers okanye i-4096 i-optical receivers kwi-20Km umgama wefiber. Ngokhetho lokufaka izibuko leOLT,GWA3530ingafaka i-TV yesathelayithi RF phezu kosinga olufanayo lweGPON okanye iXGPON network.
Izinto eziluncedo kwisathelayithi TV FTTH:
- Ezimbini zihleli izitya zababhalisi be-32 okanye amawaka ababhalisile
- Umgangatho ongcono wesignali yeSatellite kwi-fiber terminal nganye
- I-Fiber terminal ilula ukufakwa kwimizuzu emi-5 ngoyilo lwe "plug and play".
- Umamkeli wesathelayithi oqhelekileyo ovela kwiSatellite A STB okanye iSatellite B STB
Ukuba isathelayithi inezidluliseli zesathelayithi ezingaphezu kwama-32, ibhendi esezantsi kunye nebhendi ephezulu (phantsi kwethowuni ye-22KHz) yaziswa kwi-Quattro LNB ukuhlangabezana nesathelayithi eqhelekileyo yomamkeli 950MHz~2150MHz uluhlu lwamaza. Sincoma ukufaka i-twin wideband LNBGWB104Gkwisitya sesatellite.GWB104GI-LNB ine-10.4GHz LO frequency kunye neziphumo ezimbini ze-RF ezine-bandwidth ye-300MHz ~ 2350MHz, okt, i-wideband Vertical RF ilingana ne-Vertical Lower (VL) kunye ne-Vertical Higher (VH) ngelixa i-wideband Horizontal RF ilingana ne-Horizontal Lower (HL) kunye ne-Horizontal. Ephakamileyo (HH). Ekubeni i-wideband ye-RF ye-wideband ingaphaya kwe-RF ye-satellite receiver, sifuna i-Digital Channel Satellite Switcher (dCSS) chip ukuguqula i-RF ebanzi kuluhlu lomamkeli wesathelayithi. Ukongeza, umamkeli wesathelayithi kufuneka axhase umgangatho ongaguqukiyo.
Kulo mzobo ungentla,GLB3500E-4Ti-optical transmitter iguqula amawele amabini e-LNB RFs ibe yifayibha enye ye-1550nm ukusuka kuphahla lwesakhiwo esinye. Imveliso ye-optical ye-GLB3500E-4T inokuqhuba i-32pcs abamkeli be-optical ngokuthe ngqo okanye amawaka abamkeli be-optical nge-GWA3530 amplifier. Kwindlu nganye, enyeI-GLB3500E-4WRi-optical receiver ixhasa i-4 unicable receiver satellite kunye nenyeGLB3500E-4WR2i-optical receiver ixhasa i-8 unicable receiver satellite. Umamkeli ngamnye wesathelayithi unokwazi ukucacisa yonke imixholo yeFTA kwezi satellite zimbini kunye nemixholo efihliweyo ngekhadi le-CA.
