I-GLB3500M-3 Terr TV kanye ne-One wideband LNB phezu kwefayibha

Izici:

•I-Wideband LNB ne-Terr TV nge-SM eyodwa.

•I-Wideband H noma i-V yomkhawulokudonsa: 290MHz ukuya ku-2350MHz.

•Umkhawulokudonsa we-Terestrial TV: 45~806MHz.

•Hlehlisa i-14V DC uye ku-wideband LNB ku-transmitter ebonakalayo.

•I-transmitter eyodwa ye-optical isekela izamukeli ezingama-32 ze-FTTB.

•1530nm/1550nm/1570nm CWDM uhlelo.

•I-MER ephezulu ekukhishweni kwe-RF kwesamukeli ngasinye.

IMINININGWANE YOMKHIQIZO

Incazelo Yomkhiqizo

I-GLB3500M-3 iyi-modular CWDM broadband RF fiber link, idlulisa ama-290MHz ~ 2350MHz Satellite RF amabili (esekela i-UK 290MHz ~ 2340MHz noma i-Europe 300MHz ~ 2350MHz) kanye ne-45MHz ~ 806MHz eyodwa Terrestrial TV i-SM ku-multiple RF RF. I-wideband RF iku-1530nm noma i-1550nm, i-terrestrial TV RF iku-1570nm. Kukhona i-fiber optic CWDM mux noma idivayisi yedemux kusidluliseli esibonayo noma eyamukele ukuze uthole ukudluliswa kwefayibha eyodwa.

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. Ngokungafani nesistimu ye-Quattro LNB SMATV evamile, isistimu ye-wideband LNB SMATV inezixhumi ze-RF uhhafu nezinombolo zekhebula uhhafu, okonga izindleko zokudlulisela. Ngemva kwe-fiber eya esakhiweni, i-wideband SMATV isamukeli esibonakalayo kufanele isebenze ne-dCSS multiswitch ukuze ibe nokuphumayo kwe-RF okukodwa okunamabhendi ashukumisayo angu-32, lapho ibhendi yomsebenzisi ngayinye yobhalisele i-STB yesathelayithi eyodwa engasebenzi. Le fibre eyodwa eya esakhiweni kanye nekhebuli eyodwa ye-coaxial kubasebenzisi abaningi esakhiweni yenza ukufakwa nokugcinwa kwekhebula kube lula.

Isixhumanisi se-GLB3500M-3 se-fiber sihlanganisa i-GLB3500M-3T i-optical transmitter kanye ne-GLB3500M-3R yokwamukela optical. Ngama-laser/photodiode e-CWDM kanye nesekhethi yokulawula inzuzo ye-RF yomsindo ophansi, i-GLB3500M-3T eyodwa ingaletha i-RF yekhwalithi ephezulu iye kuma-32pcs aphezulu GLB3500M-3R izamukeli optic ngokuqondile.
