GLB3500MT Terr TV ma Sat Fiber Optic Transmitter
Fa'amatalaga o oloa
GLB3500M o se modular 45 ~ 2600MHz RF i luga o le fiber soʻotaga, faʻasalalau ala televise Terrestrial ma tasi L-Band RF i luga o le tasi fiber.
Direct Broadcasting Satellite (DBS) ma Direct to Home (DTH) o le auala sili ona lauiloa e fiafia ai i satelite TV i le lalolagi atoa. Ina ia faia, satelite antenna, coaxial cable, splitter poʻo le tele-switcher ma satelite receiver e manaʻomia. Ae ui i lea, o le faʻapipiʻiina o le satelite antenna atonu e faigata i le au fai saofaga o loʻo nonofo i fale mautotogi. SMATV (satellite mater antenna TV) o se fofo lelei mo tagata o loʻo nonofo i totonu o le fale poʻo le alalafaga e faʻasoa se tasi satelite ma le televise televise. Faatasi ai ma fiber cable, SMATV RF faailo e mafai ona tuʻuina atu i le 30Km mamao pe tufatufaina atu i le 32 fale mautotogi saʻo, i le 320 poʻo le 3200 poʻo le 32000 fale e ala i le GWA3530 fiber optic amplifier.
GLB3500M e aofia ai GLB3500MT transmitter module ma GLB3500MR receiver module. GLB3500MT transmitter module e tasi pe lua RF input ports ae o le GLB3500MR e tasi le RF output ports. Faatasi ai ma le laina maualuga 1550nm leisa DFB, photodiode ma maualalo le pisapisao RF maua matagaluega pulea, GLB3500MT e mafai ona tuʻuina atu le maualuga o ala televise Terrestrial ma satelite RF i luga o fiber i nai tagata fai saofaga saʻo poʻo le faitau afe o FTTH tagata fai saofaga e ala i le EDFA. Faatasi ai ma le 1310nm / 1490nm / 1550nm WDM filifiliga, GLB3500M e mafai ona faʻaofiina L-Band + TV RF i luga ole GPON / GEPON. I tafatafa o le faʻasologa faʻapitoa, GLB3500M e mafai ona maua le 19" 1RU version pe a talosagaina. O le fiber i le fale palasitika fale fale o le GLB3500MR o le GFH2000 optical LNB, lea e manaʻomia ai e le tagata fai saofaga a le FTTH le fiber e tasi i totonu ma faʻaalia ai faailo satelite i le tele o potu o le aiga.
isi vaega:
• Fale pa'u alumini ma'oti.
• Tu'ufa'atasi tu'ufa'atasiga fa'aoga RF fa'atasi ma bandwidth:45~2600MHz po'o.
• E lua mea fa'aoga RF tu'ufa'atasi, e aofia ai:
-Tasi fa'aoga TV Terrestrial, bandwidth: 174 -806 MHz.
-Ose LNB RF fa'aoga, bandwidth: 950MHz~2150MHz (13V poʻo 18V DC filifiliga mo LNB i luga ole talosaga).
• Tasi le RF fa'atauga uafu.
• Tulaga maualuga 1550nm le fa'amalo DFB Laser ma Photodiode.
• Le pisapisao maualalo RF Gain Control circuit.
