Vim li cas Fiber Optic Repeater?
Kingtone Fiber Optic Repeaters system yog tsim los daws cov teeb meem ntawm cov teeb liab tsis muaj zog ntawm lub xov tooj ntawm tes, uas yog pheej yig dua li teeb tsa qhov chaw nres tsheb tshiab (BTS).Lub luag haujlwm tseem ceeb ntawm RF Repeaters system: Rau qhov txuas hauv qab, cov cim qhia los ntawm BTS yog pub rau Master Unit (MU), MU ces hloov RF teeb liab rau laser teeb liab ces pub rau fiber ntau xa mus rau Chaw Taws Teeb (RU).RU tom qab ntawd hloov cov teeb liab laser rau RF teeb liab, thiab siv Power Amplifier los ua kom lub zog siab rau IBS lossis cov kav hlau txais xov.Rau qhov txuas mus, Yog tus txheej txheem rov qab, cov teeb liab los ntawm cov neeg siv xov tooj yog pub rau MU's MS chaw nres nkoj.Ntawm duplexer, lub teeb liab yog amplified los ntawm lub suab nrov nrov amplifier los txhim kho lub teeb liab zog.Tom qab ntawd cov teeb liab raug pub rau RF fiber optical module ces hloov mus rau laser teeb liab, ces lub teeb liab laser xa mus rau MU, laser teeb liab los ntawm RU yog hloov mus rau RF teeb liab los ntawm RF optical transceiver.Tom qab ntawd cov teeb liab RF tau nthuav dav rau ntau lub zog cov cim pub rau BTS.
Nta:
- Fiber Optic RF Repeater yog ib qho kev txhim khu kev qha los txuas ntxiv thiab txhim kho thaj tsam ntawm TETRA 400MHz network
- Muaj ob lub ntsiab modules, Master thiab ntau Slave units.
- 33, 37, 40 lossis 43dBm sib xyaw tso zis hluav taws xob, ua tau raws li cov qauv txheej txheem
- Ib qho yooj yim teb installation thiab txij nkawm txo rollout thiab ua hauj lwm cov nqi
- Lub teeb liab kis tau tus mob hauv fiber ntau optic repeater tsis cuam tshuam los ntawm kev cuam tshuam sab nraud
- Muab kev pabcuam RF ceev heev rau koj TETRA Base-Station
- Compact Size thiab High Performance nyob rau hauv waterproof enclosure haum rau sab nraum zoov thiab sab hauv tsev installation
