GLB3300MG GPS okun opitiki extender
ọja Apejuwe
GLB3300MG ọna asopọ okun le firanṣẹ GNSS (GPS, GLONASS, Galileo, Beidou) satẹlaiti lilọ kiri RHCP RF ifihan agbara lati eriali ita si eyikeyi ọfiisi inu inu10Ijinna okun km.
GNSS jẹ Eto Satẹlaiti Lilọ kiri Agbaye, nipataki pẹlu GPS (AMẸRIKA), GLONASS (Russia), GALILEO (European Union) ati BDS (China). Ti o da lori awọn satẹlaiti pupọ ti o yika ilẹ, GNSS pese awọn olumulo pẹlu ipo, lilọ kiri, ati awọn iṣẹ akoko (PNT) ni agbaye tabi ipilẹ agbegbe. .
Bii Intanẹẹti, GNSS jẹ ẹya pataki ti awọn amayederun alaye agbaye. Ọfẹ, ṣiṣi, ati iseda igbẹkẹle ti GNSS ti yori si idagbasoke awọn ọgọọgọrun awọn ohun elo ti o kan gbogbo abala ti igbesi aye ode oni. Imọ-ẹrọ GNSS wa ni ohun gbogbo lati awọn foonu alagbeka ati awọn aago ọwọ si awọn ọkọ ayọkẹlẹ, awọn akọmalu, awọn apoti gbigbe, ati awọn ATMs.
Gbogbo awọn eriali satẹlaiti nilo aaye ṣiṣi lati gba awọn ifihan agbara RF lati ọrun. Ifihan GNSS RF ni attenuation giga lori okun coaxial. GLB3300MG fiber ọna asopọ fa iṣẹ GNSS ati awọn ifihan agbara simulator GNSS lati ita si ita ati inu ilẹ. Iṣẹ GNSS le wa ni awọn ọfiisi inu ile, awọn ọja ipamo, awọn tunnels, metros, awọn ilẹ ipakà ti awọn skyscrapers.
GNSS RF ipele jẹ nipa -120dBm, Elo kere ju awọn deede igbohunsafefe Satellite TV. GLB3300MG ti ni ariwo kekere GaAs amplifiers, laser linearity giga ati photodiode lati rii daju didara ifihan agbara GNSS ti o dara julọ lẹhin gbigbe okun. GLB3300MG ṣiṣẹ daradara fun GPS lori okun, BDS lori awọn ohun elo okun. GLB3300MG le ṣiṣẹ pẹlu simulator GNSS lati funni ni aaye kan si awọn ifihan agbara lilọ-ojuami pupọ lori awọn kebulu okun opitiki.
Awọn ẹya miiran:
•Ile Simẹnti Aluminiomu Die tabi 19” 1RU ile inu ile.
•Atilẹyin GPS GLONASS Galileo Beidou Satellite RF ifihan agbara lori okun.
•Nfunni agbara 5.0V DC fun eriali GNSS ita gbangba.
•Laser linearity giga ati Photodiode.
•GaAs Low Noise ampilifaya.
