IMINININGWANE YOMKHIQIZO

Incazelo Yomkhiqizo

I-GLB3500M-8yin a8ch CWDM Satellite RF fibre link, transmitting8IFs kusuka2Quattro LNBs at2Izitsha Zesathelayithi ezihlukene kanye ne-TV ye-terrestrial RF engu-1 ngaphezulu kwe-SM fiber eyodwa 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 ludinga amakhebuli angu-9 e-RF ukusuka ophahleni lwesakhiwo kuya kuma-multiswitch, anikezela ababhalisile abangaphansi kuka-100 esakhiweni esisodwa.I-GLB3500M-8 inika amandla i-SMATV phezu kwefayibha eya ezakhiweni ezengeziwe nababhalisile.Ihlangene ne-PLC fibre splitter kanye nama-multiswitch ayi-cascading esakhiweni ngasinye, i-GLB3500M-8 ingasabalalisa ama-Quattro LNB amabili kanye ne-Terr TV kwababhalisile abangaphezu kuka-3200 emphakathini.Lolu uhlelo olujwayelekile lwekhebula le-fiber coaxial ku-TV yesathelayithi.

Isixhumanisi se-GLB3500M-8 se-fiber sihlanganisa i-GLB3500M-8T i-fiber optic transmitter kanye ne-GLB3500M-8R ye-fiber optic receiver.Ngama-laser/photodiode e-CWDM kanye nesekhethi yokulawula inzuzo ye-RF yomsindo ophansi, i-GLB3500M-8T eyodwa ingaletha i-RF yekhwalithi ephezulu iye kuma-32pcs GLB3500M-8R aphezulu amukelayo ngaphakathi kwebanga le-fiber elingu-5Km.
