Daim ntawv thov ntawm Duplexers hauv Sab Hauv Tsev Distribution Systems

Nrog rau kev xav tau ntau ntxiv rau kev sib txuas lus xov tooj ntawm tes thiab pej xeem kev nyab xeeb, cov kav hlau txais xov sab hauv tsev (DAS) tau siv dav hauv cov chaw xws li tshav dav hlau, subways, tsev kho mob, thiab cov chaw lag luam loj los hais txog qhov chaw nyob sab hauv tsev qhov muag tsis pom kev thiab teeb liab attenuation. Ntawm ntau yam tseem ceeb hauv DAS systems, lubduplexeryog ib qho tseem ceeb thiab tseem ceeb ntawm cov khoom.

Covduplexer covLub luag haujlwm tseem ceeb yog txhawm rau ua kom uplink thiab downlink cov cim qhia kom sib koom tib lub kav hlau txais xov, sib cais ob lub teeb liab zoo los ntawm kev sib cais siab tsim los tiv thaiv kev cuam tshuam. Cov yam ntxwv no muab cov txiaj ntsig hauv qab no hauv DAS systems:

Txo cov kav hlau txais xov suav: Cov kav hlau txais xov sib koom ua rau txo qis kev teeb tsa thiab cov nqi cabling;

Txhim kho cov teeb liab zoo: Tswj kev sib txuas lus ruaj khov hauv ntau tus qauv, ntau qhov chaw ib puag ncig;

Txhawb kev xa tawm ntau qhov xwm txheej: Txawm hais tias nyob rau hauv pej xeem kev nyab xeeb DAS, cov tsev lag luam, lossis ntau tus neeg ua haujlwm sib koom tes,duplexerstuaj yeem ua tau ntseeg tau.

Hauv kev sib txuas lus kev nyab xeeb rau pej xeem,duplexersxyuas kom meej VHF / UHF kev sib txuas lus rau tub ceev xwm, hluav taws kub, thiab kev sib txuas lus kho mob xwm txheej ceev. Hauv cov chaw lag luam loj, lawv txo cov cuab yeej hneev taw thiab txhim kho kev pab cuam sib xws. Nyob rau hauv ib puag ncig nyuaj xws li tshav dav hlau thiab subways,duplexerspab ua kom muaj kev sib cais zoo thiab kev sib koom ua ke ntawm kev sib koom ua ke ntawm ntau tus neeg ua haujlwm, ntau lub cim qhia.

Nrog kev sib cais siab, tsis tshua muaj qhov poob qis, muaj zog tuav lub peev xwm, thiab tsim qauv tsim,duplexersxyuas kom muaj kev ua haujlwm siab ntawm DAS systems nyob rau hauv ib puag ncig uas muaj ntau yam qauv, xws li LTE, 5G, thiab kev nyab xeeb rau pej xeem, sib koom ua ke. Lawv yog cov khoom tseem ceeb rau kev sib txuas lus hauv tsev niaj hnub.
