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

I-GLB3500M-3 Terr TV kunye ne-Wideband ye-LNB enye ngaphezu kwefayibha Umfanekiso obonakalayo

Iimbonakalo:

•Wideband LNB kunye Terr TV phezu SM enye.

•I-Wideband H okanye i-V bandwidth: 290MHz ukuya kwi-2350MHz.

•I-bandwidth ye-TV ye-Terestrial: 45 ~ 806MHz.

•Ukubuyisela umva i-14V DC ukuya kwi-wideband LNB kwi-transmitter ebonakalayo.

•Isidluliseli samehlo esinye sixhasa ii-32 ze-FTTB zamkeli zamehlo.

•1530nm/1550nm/1570nm inkqubo yeCWDM.

IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-GLB3500M-3 yimodyuli ye-CWDM Broadband RF ifayibha link, ithumela ezimbini 290MHz ~ 2350MHz Satellite RF (ixhasa UK 290MHz ~ 2340MHz okanye iYurophu 300MHz ~ 2350MHz) kunye ne45MHz enye ~ 806MHz Terrestrial ifayibha SM rhuma ifayibha ezininzi RF kwiTV enye.I-wideband RF ikwi-1530nm okanye i-1550nm, i-terrestrial TV RF ikwi-1570nm.Kukho i-fiber optic CWDM mux okanye isixhobo sedemux kwisidluliseli samehlo okanye ukufumana ukuqonda ukuhanjiswa kwefayibha enye.

I-SMATV (iSatellite Master Antenna TV) idume ngokunikezela ngeTV yesathelayithi kunye neTV yasemhlabeni kubabhalisi abahlala kumagumbi okanye kuluntu.I-SMATV yesiNtu inokusasaza imixholo ye-eriyali eyinkosi ngokutshintshela kwisathelayithi yabamkeli ngentambo eyicoaxial.Ngenxa yelahleko ephezulu kwi-frequency ephezulu yesathelayithi, umgama wentambo ye-SMATV ungaphantsi kwe-150 yeemitha kunye ne-IF yeamplifier ye-intanethi.Ngokungafaniyo nenkqubo ye-Quattro LNB ye-SMATV eqhelekileyo, inkqubo ye-wideband ye-LNB ye-SMATV inesiqingatha seziqhagamshelo ze-RF kunye neenombolo ze-cable ezinesiqingatha, ezigcina iindleko zothumelo.Emva kwefiber kwisakhiwo, i-wideband SMATV i-optical receiver kufuneka isebenze ne-dCSS multiswitch ukuze ibe nemveliso enye ye-RF enama-userbands aguqukayo angama-32, apho ibhendi yomsebenzisi nganye yomrhumi omnye we-STB yesathelayithi engabonakaliyo.Le fiber enye kwisakhiwo kunye nentambo enye ye-coaxial kubasebenzisi abaninzi kwisakhiwo yenza ukufakwa kwentambo kunye nokugcinwa kube lula.

I-GLB3500M-3 i-fiber link iquka i-GLB3500M-3T i-optical transmitter kunye ne-GLB3500M-3R i-optical receiver.Nge-CWDM lasers / photodiode kunye nesandi esisezantsi se-RF yokulawula ukufumana isiphaluka, enye i-GLB3500M-3T inokuhambisa umgangatho ophezulu we-RF ukuya kwi-32pcs ephezulu ye-GLB3500M-3R yabamkeli be-optic ngokuthe ngqo.
