GLB3500M-4 Terr TV uye Imwe Quattro LNB pamusoro pefiber
Product Description
GLB3500E-4R setiraiti TV FTTH Optical LNB ndeye maviri-core faibha yekupinza optic inogamuchira, inoshandura ina wideband RFs kubva kumasetelliti maviri (semuenzaniso, Nilesat neArabsat) pamusoro pemasaini efiber kuita imwe RF inobuda kweanosvika mana setiraiti inogamuchira mumba imwe.Kushanda ne2pcs Greatway GLB3500E-2T satellite TV optical transmitters kubva kune maviri mafiber inputs, GLB3500E-4R yakavaka-muSatCR module ichichinja iyo wideband RF kubva kumasetelliti maviri, inoburitsa 4 setiraiti mushandisi mabhendi pane imwe SatCR RF chiteshi kune 4 unicable satellite inogamuchira.
SMATV (Satellite Master Antenna TV) yakakurumbira kupa satellite TV uye yepasi TV kune vanyoreri vanogara mudzimba kana munharaunda.Yechinyakare SMATV inogona kugovera iyo master antenna zvirimo kuburikidza nemultiswitch kune vanogamuchira setiraiti pamusoro pecoaxial tambo.Nekuda kwekurasikirwa kwakanyanya pakakwirira satellite frequency, SMATV tambo kureba isingasviki zana nemakumi mashanu emamita kunyangwe neIF online amplifier.Masevhisi maviri eSMATV system inoda 9 RF tambo kubva padenga rekuvaka kusvika kune inoyerera maswiti akawanda, ichishandira vasingasviki zana vanyoreri muchivakwa chimwe.Kune maviri setiraiti SMATV pamusoro pefiber, Greatway Technology ine GLB3500M-8 seFTTB mhinduro uye GLB3500E-4R seFTTH mhinduro.Mhinduro yeFTTB inofanirwa kuve nesetiraiti yenguva dzose STB, nepo FTTH mhinduro ichifanirwa kunge iine satellite STB inotsigira unicable.
GLB3500E-4R ine 1310nm/1490nm/1550nm WDM sarudzo port yekushanda pamwe chete neGPON ONU mune chero FTTH application, iyo inogonesa zvizere setiraiti LNB zvirimo zviiswe muGPON system.
