Product Description
TETRA cable-access MDAS Fiber Optic Repeater inoshandiswa kuwedzera chiratidzo cheTETRA midziyo.Iyo Master Optical Unit System inotora chiratidzo cheBTS cheTETRA uye yochishandura kuita optic chiratidzo uye inotamisa chiratidzo chekusimudzira kuRemote Optical Unit kuburikidza netambo dzefiber optic.Iyo Remote Optical Unit ichashandura chiratidzo cheoptic kuita chiratidzo cheTETRA uye yobva yashandura Downlink Amplifier uye ichipa chiratidzo kunzvimbo uko mambure ekuvhara basa asina kukwana.
Uye iyo nharembozha inokwidziridzwa uye inotumirwa kuBTS kuburikidza neyakapesana.Iyo yekugovera sisitimu nekambani yedu yakazvimirira yekutsvagisa nekusimudzira inoumbwa neMaster Optical Unit uye Remote Optical Unit.Iyo yemukati module inosanganiswa, iyo yakanyanya kusanganiswa tekinoroji inovandudza kugadzikana kwemidziyo.
Product Features

400 uhf mobile signal link inodzokorora Zvimiro:
1.Monitoring software inogona kuvandudzwa munharaunda kana kure.
2.Wide dynamic range, yakaderera simba rekushandisa uye ruzha nhamba.Dziviriro kubva pamusoro pemagetsi, pamusoro pezvino uye pamusoro pekushisa
3.Kuzviparadzanisa kwepamusoro kubva kumusoro kusvika kune downlink kuti uvandudze kugadzikana kwepamusoro.
4.Kuvimbika kwepamusoro uye MTBF≥100,000 maawa
5.Perfect kure uye yemunharaunda network monitoring basa.
6.Dzivisa kupindira kubva ku-co-frequency
7.Kurisa nzvimbo yekuvhara neomni directional antenna
8Wedzera chiratidzo chinhambwe che base station
9.Backup mabhatiri
10.Main module self-test uye auto alarm.
11.Door vhura alarm

TETRA 400 REPEATER Applications
Kuwedzera kuvharwa kwechiratidzo chekuzadza chiratidzo bofu nzvimbo iyo chiratidzo chisina simba
kana kusavapo.
Kunze: Nhandare, Nharaunda dzeKushanya, Makosi eGorofu, Tunnels, Mafekitori, Dunhu reMigodhi, Misha nezvimwe.
Indoor: Hotels, Exhibition Centers, Basement, Shopping
Mall, Mahofisi, Packing Lots etc.
Iyo inonyanya kushanda kune yakadaro kesi:
Iyo inodzokorora inogona kuwana nzvimbo yekuisa iyo inogona kugamuchira yakachena BTS chiratidzo pane yakasimba zvakakwana nhanho sezvo iyo Rx Level mune inodzokorora saiti inofanirwa kupfuura -70dBm;Uye inogona kusangana nezvinodiwa zvekuzviparadzanisa neantenna kudzivirira wega-oscillation.
