GLB3500M-3 Terr TV uye Imwe wideband LNB pamusoro pefiber
Product Description
GLB3500M-3 ndeye modular CWDM Broadband RF faibha link, inotumira maviri 290MHz ~ 2350MHz Satellite RF (inotsigira UK 290MHz ~ 2340MHz kana Europe 300MHz ~ 2350MHz) uye imwe 45MHz ~ 806MHz Terrestrial faibha SM kunyorera pane imwe chete.Iyo wideband RF iri pa1530nm kana 1550nm, iyo yepasi TV RF iri pa1570nm.Kune fiber optic CWDM mux kana demux mudziyo pane optical transmitter kana kugashira kuona imwe fiber kutapurirana.
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.Kusiyana yenguva dzose Quattro LNB SMATV system, wideband LNB SMATV system ine hafu yeRF yekubatanidza uye hafu yetambo nhamba, iyo inochengetedza mutengo wekutapurirana.Mushure mefiber kuchivakwa, wideband SMATV optical receiver inofanirwa kushanda nedCSS multiswitch kuti ive neRF imwe chete inobuda ine makumi matatu nemaviri emagetsi mabhendi, apo yega yega mushandisi weiyo unicable satellite STB munyoreri.Iyi imwe fiber kuchivakwa uye imwe coaxial tambo kune vakawanda vashandisi muchivako inoita kuti kuisirwa tambo uye kugadzirisa kuve nyore.
GLB3500M-3 fiber link inosanganisira GLB3500M-3T optical transmitter uye GLB3500M-3R inogamuchira yemaziso.Iine CWDM lasers/photodiode uye yakaderera ruzha RF kuwana control circuit, imwe GLB3500M-3T inogona kuendesa yakakwira mhando RF kusvika pakakwirira 32pcs GLB3500M-3R optic vanogamuchira zvakananga.
Zvimwe Zvimiro:
• Compact aluminum housing.
