Kingtone 43dBm 20W Tetra DMR UHF BDA Off-air Channel Selective Fiber Optic Repeater Signal Extender ya Tunnel & In-Building DAS 400MHz Radio System Telecommunication

Chifukwa chiyani Fiber Optic Repeater?
Dongosolo la Kingtone Fiber Optic Repeaters lapangidwa kuti lithetse mavuto a siginecha yofooka yam'manja, yomwe ndiyotsika mtengo kwambiri kuposa kukhazikitsa Base Station (BTS).Kugwira ntchito kwakukulu kwa RF Repeaters system: Pa ulalo wapansi, ma sign ochokera ku BTS amaperekedwa ku Master Unit (MU), MU kenako amasintha chizindikiro cha RF kukhala chizindikiro cha laser kenako amadyetsa ku fiber kuti atumize ku Remote Unit (RU).RU ndiye sinthani chizindikiro cha laser kukhala chizindikiro cha RF, ndikugwiritsa ntchito Power Amplifier kukulitsa mphamvu yayikulu kukhala IBS kapena mlongoti wophimba.Pa ulalo wa mmwamba, Ndi njira yosinthira, ma siginecha ochokera kwa ogwiritsa ntchito amaperekedwa ku doko la MU la MS.Kudzera pa duplexer, siginecha imakulitsidwa ndi amplifier yaphokoso yotsika kuti ipititse patsogolo mphamvu yazizindikiro.Kenako ma sign amadyetsedwa ku RF fiber optical module kenako amasinthidwa kukhala ma laser, ndiye chizindikiro cha laser chimatumizidwa ku MU, chizindikiro cha laser chochokera ku RU chimasinthidwa kukhala chizindikiro cha RF ndi RF Optical transceiver.Kenako ma siginecha a RF amakulitsidwa kuzizindikiro zamphamvu zoperekedwa ku BTS.

Mawonekedwe:

• Fiber Optic RF Repeater ndi njira yodalirika yowonjezeretsa ndikuwongolera malo ofikira a TETRA 400MHz network.
• Zili ndi zigawo ziwiri zazikulu, Master ndi mayunitsi angapo akapolo.
• 33, 37, 40 kapena 43dBm gulu lotulutsa mphamvu, kukumana ndi machitidwe
• Kuyika ndi kukonza zinthu mosavuta kumachepetsa ndalama zoyendetsera ntchito
• Kutumiza kwa chizindikiro mu fiber optic repeater sikusokonezedwa ndi zokopa zakunja
• Perekani chithandizo chachangu cha RF ku TETRA Base-Station yanu
• Kukula Kwapang'onopang'ono ndi Kuchita Kwapamwamba m'malo osalowa madzi oyenera kuyika panja ndi m'nyumba
