IMINININGWANE YOMKHIQIZO

Incazelo Yomkhiqizo

I-GLB3500M-16 iyisixhumanisi se-fiber ye-16ch CWDM Satellite RF, idlulisa ama-IF angu-16 asuka kuma-Quattro LNB angu-4 kumaSatellite Dishes angu-4 kanye ne-terrestrial TV RF engu-1 ngefayibha eyodwa ye-SM kwababhalisile abaningi.Ubude begagasi obubonakalayo be-CWDM ngayinye buphethe isignali eyodwa ye-950 ~ 2150MHz RF (noma i-174~2150MHz, kuhlanganise ne-Terrestrial TV), iqinisekisa ukusebenza kwe-RF okuhle kakhulu nokuhlukaniswa phakathi kwe-polarity yesathelayithi.

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.Uhlelo olujwayelekile lwe-Quattro LNB SMATV olune ludinga amakhebuli e-RF angu-17 ukusuka ophahleni lwesakhiwo kuya kuma-multiswitch, anikezela ababhalisile abangaphansi kwe-100 esakhiweni esisodwa.I-GLB3500M-16 inika amandla i-SMATV phezu kwefayibha ezakhiweni eziningi nababhalisile.Ihlangene ne-PLC fibre splitter kanye nama-multiswitch e-cascading esakhiweni ngasinye, i-GLB3500M-16 ingasabalalisa ama-Quattro LNB amane kanye ne-Terr TV kwababhalisile abangaphezu kuka-3200 emphakathini.Lolu uhlelo olujwayelekile lwekhebula le-fiber coaxial ku-TV yesathelayithi.

Isixhumanisi se-GLB3500M-16 se-fiber sihlanganisa i-GLB3500M-16T i-fiber optic transmitter kanye ne-GLB3500M-16R ye-fiber optic receiver.Ngama-laser/photodiode e-CWDM kanye nesekethe yokulawula inzuzo ye-RF yomsindo ophansi, i-GLB3500M-16T eyodwa ingaletha i-RF yekhwalithi ephezulu iye kuma-32pcs GLB3500M-16R afinyelela kuma-optical afinyelela phezulu ngaphakathi kwebanga le-fiber elingu-5Km.
