GLB3500MT Terr TV uye Sat Fiber Optic Transmitter
Product Description
GLB3500M ndeye modular 45 ~ 2600MHz RF pamusoro pe fiber link, inotumira Terrestrial TV chiteshi uye imwe chete L-Band RF pamusoro pe fiber imwe.
Yakananga Nhepfenyuro Satellite (DBS) uye Yakananga Kumba (DTH) ndiyo inonyanya kufarirwa nzira yekunakidzwa nesatellite TV pasi rese. Kuti uzviite, satellite antenna, coaxial tambo, splitter kana multi-switcher uye satellite inogamuchira inodiwa. Nekudaro, kuisa satellite antenna kunogona kunetsa kune vanyoreri vanogara mudzimba. SMATV (satellite mater antenna TV) mhinduro yakanaka kune vanhu vanogara muchivakwa kana nharaunda kuti vagovane imwe setiraiti dish uye terrestrial TV antenna. Iine fiber tambo, SMATV RF siginecha inogona kuendeswa ku30Km kure kana kugoverwa kudzimba makumi matatu nembiri zvakananga, ku320 kana 3200 kana 32000 dzimba kuburikidza neGWA3530 fiber optic amplifier.
GLB3500M ine GLB3500MT transmitter module uye GLB3500MR inogamuchira module. GLB3500MT transmitter module ine imwe kana maviri RF yekupinza zviteshi nepo GLB3500MR ine imwe RF yekubuda port. Iine yakakwira mutsara 1550nm isina kunyungudutswa DFB laser, photodiode uye yakaderera ruzha RF kuwana yekudzora wedunhu, GLB3500MT inogona kuendesa yakakwira mhando yeTerestrial TV chiteshi uye satellite RF pamusoro pe fiber kune vashoma vanyoreri zvakananga kana zviuru zvevanyoreri veFTTH kuburikidza neEDFA. Iine 1310nm/1490nm/1550nm WDM sarudzo, GLB3500M inogona kuisa L-Band+TV RF pamusoro peGPON/GEPON. Padivi peiyo modular vhezheni, GLB3500M inogona kuva ne19”1RU vhezheni pakukumbira. Iyo fiber kune yeimba yepurasitiki yeimba vhezheni yeGLB3500MR iGFH2000 Optical LNB, uko munyoreri weFTTH anongoda imwe fiber mukati uye anoburitsa masaini esatellite kumakamuri akati wandei mumhuri.
Zvimwe Zvimiro:
• Compact aluminum die cast housing.
• Imwechete yakasanganiswa RF inopinza ine bandwidth:45~2600MHz kana.
• Mapiritsi maviri akapatsanurwa eRF, anosanganisira:
-Kupinda kweTerestrial TV, bandwidth: 174 -806 MHz.
-Imwe LNB RF inopinza, bandwidth: 950MHz ~ 2150MHz (13V kana 18V DC sarudzo yeLNB pakukumbira).
• Imwe RF inobuda pachiteshi.
• High Linearity 1550nm isina kutonhorera DFB Laser uye Photodiode.
• Low ruzha RF Gain Control redunhu.
