I-GLB3500E-4R I-Nilesat ne-Arabsat ngaphezu kwemicu emibili ekhaya elilodwa
Incazelo Yomkhiqizo
I-TV yesathelayithi ye-GLB3500E-4R i-FTTH Optical LNB iyisamukeli se-fiber optic esinama-core-core, esiguqula ama-RF amane e-wideband asuka kumasathelayithi amabili (isb., i-Nilesat ne-Arabsat) phezu kwamasignali efayibha abe okukhiphayo kwe-RF okukodwa kokufika kwezamukeli zesathelayithi ezi-4 ekhaya elilodwa. Isebenza nama-2pcs Greatway GLB3500E-2T ama-satellite TV optical transmitters avela kokufakwayo okubili kwefayibha, i-GLB3500E-4R inemojula eyakhelwe ngaphakathi ye-SatCR eshintsha i-wideband RF isuka kumasathelayithi amabili, ikhiphe amabhendi abasebenzisi besathelayithi angu-4 embotsheni eyodwa ye-SatCR RF yabamukeli abanesathelayithi abangabambeki.
I-SMATV (Satellite Master Antenna TV) idume ngokunikeza i-TV yesathelayithi kanye ne-terrestrial TV kwababhalisile abahlala emafulethini noma emphakathini. I-SMATV yendabuko ingasabalalisa okuqukethwe kwe-antenna enkulu ngokusebenzisa i-multiswitch kuya ezamukeli zesathelayithi ngekhebula eliqinile. Ngenxa yokulahlekelwa okuphezulu kumaza wesathelayithi ephezulu, ibanga lekhebula le-SMATV lingaphansi kwamamitha ayi-150 ngisho ne-IF iamplifier eku-inthanethi. Amasathelayithi amabili ajwayelekile Uhlelo lwe-SMATV ludinga amakhebuli e-RF angu-9 ukusuka ophahleni lwesakhiwo kuya kuma-multiswitch agelezayo, asebenzela ababhalisile abangaphansi kwe-100 esakhiweni esisodwa. Kumasathelayithi amabili i-SMATV phezu kwefayibha, iGreatway Technology ine-GLB3500M-8 njengesixazululo se-FTTB kanye ne-GLB3500E-4R njengesixazululo se-FTTH. Isixazululo se-FTTB kufanele sibe ne-STB yesathelayithi evamile, kuyilapho isixazululo se-FTTH kufanele sibe nesathelayithi ye-STB esekela unicable.
I-GLB3500E-4R ine-1310nm/1490nm/1550nm imbobo yenketho ye-WDM yokusebenzisana ne-GPON ONU kunoma yiluphi uhlelo lwe-FTTH, oluvumela okuqukethwe kwesathelayithi egcwele ye-LNB kufakwe ohlelweni lwe-GPON.
Ezinye izici:
•Izindlu zepulasitiki eziqinile.
•Okokufaka okubili kwefayibha ye-SC/APC kanye nokuphumayo kwe-RF okukodwa.
•I-High Linearity Photodiode.
•Ibanga le-Optical AGC: -6dBm ~ +1dBm.
•Imbobo eyodwa ye-SatCR RF yabamukeli abangafika kwabangu-4 abangasebenzi.
•Sat RF Band: 950~2150MHz.
•I-Terrestrial TV RF Ububanzi: 88~250MHz.
•Ihambisana namazinga we-EN50494+EN50607.
•Imbobo ye-WDM eyinketho eya ku-GPON ONU.
•Inketho: Imbobo eyodwa ye-SatCR RF yabamukeli abangafika kwabayi-8 abangatholakali.
