Product Description

TETRA cable-access MDAS Fiber Optic Repeater yog siv los nthuav cov teeb liab ntawm TETRA cov cuab yeej.Master Optical Unit System ntes BTS teeb liab ntawm TETRA thiab hloov nws mus rau hauv cov teeb liab optic thiab xa cov teeb liab amplified mus rau Chaw Taws Teeb Kho qhov muag ntawm fiber ntau optic cables.Lub Chaw Taws Teeb Kho qhov muag yuav rov hloov kho qhov teeb meem kho qhov muag rau hauv TETRA teeb liab thiab tom qab ntawd sib tham Downlink Amplifier thiab muab cov teeb liab rau cov cheeb tsam uas qhov kev pab them nqi ua haujlwm tsis txaus.

Thiab lub teeb liab ntawm lub xov tooj ntawm tes kuj tseem tau nthuav dav thiab rov xa mus rau BTS ntawm qhov kev coj rov qab.Qhov kev faib tawm los ntawm peb lub tuam txhab kev tshawb fawb ywj pheej thiab kev txhim kho yog tsim los ntawm Master Optical Unit thiab Remote Optical Unit.Internal module yog kev koom ua ke, kev sib koom ua ke zoo heev yog txhim kho kev ruaj ntseg ntawm cov khoom siv.

Khoom nta

Cov qib siab, siab muaj, yooj yim rau kev tswj;

Sab hauv txais kev saib xyuas ntse, yooj yim los nrhiav qhov tsis raug rau kev tswj hwm;

Tsawg zog noj, zoo heev tshav kub dissipation;

High linearity PA, siab system nce;

Kev saib xyuas hauv zos thiab thaj chaw deb;

Compact me me, hloov tau rau kev teeb tsa thiab hloov chaw;

ETSI tau tshaj

Mainfeature

400 uhf mobile teeb liab txuas repeater Nta:

1.Monitoring software tuaj yeem hloov kho hauv zos lossis nyob deb.

2.Wide dynamic ntau, tsawg zog noj thiab suab nrov daim duab.Kev tiv thaiv los ntawm dhau voltage, dhau tam sim no thiab tshaj qhov kub thiab txias

3.Kev sib cais siab ntawm uplink mus rau downlink los txhim kho kev ruaj ntseg siab.

4.Kev ntseeg siab thiab MTBF≥100,000 teev

5.Perfect tej thaj chaw deb thiab hauv zos network xyuas muaj nuj nqi.

6.Tsis txhob cuam tshuam los ntawm kev sib koom ua ke

7.Ua kom lub cheeb tsam npog nrog omni directional kav hlau txais xov

8 Txuas lub teeb liab nyob deb ntawm lub hauv paus chaw nres tsheb

9. Cov roj teeb thaub qab

10.Main module self-test thiab nws pib tswb.

11.Qhov rooj qhib tswb

12ALC (auto-level control), thiab lwm yam.

Daim ntawv thov & scenarios

TETRA 400 REPEATER Daim Ntawv Thov
Txhawm rau nthuav cov teeb liab kev pab them nqi ntawm cov teeb liab qhov muag tsis pom qhov chaw teeb liab tsis muaj zog
los yog tsis muaj.
Sab nraum zoov: tshav dav hlau, Tourism Regions, Golf Course, Tunnels, Factories, Mining Districts, Zos thiab lwm yam.
Sab hauv: Chaw ntiav pw, Exhibition Centers, Basements, Khw
Malls, Chaw Ua Haujlwm, Ntim Ntau thiab lwm yam.
Nws yog feem ntau siv rau cov xwm txheej zoo li no:
Tus repeater tuaj yeem nrhiav qhov chaw teeb tsa uas tuaj yeem tau txais cov teeb liab BTS ntshiab ntawm qhov muaj zog txaus raws li Rx Qib hauv qhov chaw repeater yuav tsum ntau dua -70dBm;

Thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj kev sib cais ntawm kav hlau txais xov kom tsis txhob muaj tus kheej oscillation.
