IMINININGWANE YOMKHIQIZO

Incazelo Yomkhiqizo

I-GLB3500M-6 iyi-modular 6ch CWDM Satellite RF fiber link, idlulisa i-6ch wideband 174MHz ~ 2350MHz RF phezu kwefayibha eyodwa ye-SM kuya kwesisodwa noma isamukeli sokubonwa okuningi. Ubude begagasi obubonakalayo be-CWDM ngayinye buthwala i-RF eyodwa engu-174~2350MHz, esekela i-Terrestrial TV 174~806MHz noma 950~2150MHz noma inhlanganisela ye-Terr TV ne-Sat RF, iqinisekisa ikhwalithi yesignali ye-RF enhle kakhulu nokuhlukaniswa phakathi kwamasignali e-RF.

I-GLB3500M-6 yakhelwe ikakhulukazi izinhlelo zokusebenza ezimbili: izinti zesathelayithi eziningi ku-TV Headend kanye ne-SMATV.

Uma kuqhathaniswa nesethelayithi i-RF phezu kwentambo ye-coaxial kuya ku-TV Headend, i-GLB3500M-6 inezinzuzo ezintathu: 1. Ubukhulu obungu-6 be-antenna RFs phezu kwe-SM fiber eyodwa ukuya ehhovisi le-Headend kanye nebanga elide kakhulu ukusuka kumamitha ayi-100 ukuya ku-10Km; 2. Ukuvikelwa kokukhanyisa ezintweni ze-Headhead ngenxa yekhebula le-fibre elingaqhubeki; 3. Ukuhlukaniswa okuphansi phakathi kwezindawo zeSatellite dish kanye nendawo yemishini ye-Headend.

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 kumafrikhwensi e-IF yesathelayithi ephezulu, ibanga lekhebula le-SMATV lingaphansi kwamamitha ayi-150 ngisho ne-IF ye-amplifier eku-inthanethi. I-GLB3500M-6 inika amandla i-SMATV phezu kwefayibha eya ezakhiweni ezengeziwe nababhalisile ebangeni le-fibre engaba ngu-5Km. Ihlangene ne-PLC fibre splitter kanye ne-cascading multiswitch esakhiweni ngasinye, i-GLB3500M-6 ingasabalalisa ama-RF antenna amasathelayithi amaningi kanye ne-Terr TV enanini lababhalisile emphakathini.

Isixhumanisi se-GLB3500M-6 se-fiber sihlanganisa i-GLB3500M-6T i-optical transmitter kanye ne-GLB3500M-6R yokwamukela optical. Ngama-laser/photodiode e-CWDM kanye nesekhethi yokulawula inzuzo ye-RF yomsindo ophansi, i-GLB3500M-6T eyodwa ingaletha i-RF yekhwalithi ephezulu iye kuma-32 GLB3500M-6R aphezulu ezamukeli ezibonakalayo.
