Qhov ntsuas qhov ntsuas ntawm cov neeg coaxial clesaxial?
Hluav taws xob tseem ceeb.
(1) Tus yam ntxwv cuam tshuam ntawm Coaxial Cable yog 50 ±, thiab impedance ntawm ib qho nruab nrab ntawm ib nrab nqi ntawm ± 3 ω thiab qhov ntev tsawg dua 2m.
(2) Lub Delenuation ntawm Coaxial Cable feem ntau yog hais txog cov neeg muaj nuj nqis ntawm 500 meter ntev sib tshooj. Thaum ntsuas nrog 10MHz sine yoj, nws tus nqi tsis tshaj 8.5db (17db / km. Mais); Thaum ntsuas nrog 5mHz sine yoj, nws tus nqi tsis tshaj 6.0dB (12dB / kmerct).
(3) Cov kis tau qis dua yuav tsum tau rau coaxial cable kis yog 0.77c (C yog qhov ceev ntawm lub teeb).
(4) Tus lej ntawm lub Center tus neeg saib xyuas thiab daim thaiv kev tsis kam ntawm coaxial xee xee yuav tsis pub tshaj 10 m offs / m (ntsuas ntawm 20 degree).
Lub cev tsis muaj zog:
Coaxial cables muaj cov neeg saib xyuas hluav taws xob rwb thaiv tsev cov ntaub ntawv txheej txheej ntawm Mesh ntaub thiab sab nraud cov khoom siv txheej. Coaxial clesles tau yooj yim hloov tau los txhawb txoj kev khoov hluav taws xob ntawm 254mm (10 ntiv tes). Tus Thawj Saib Xyuas Central yog lub tooj hlau tooj liab nrog txoj kab uas hla ntawm 2.17mm ± 0.013mm. Cov khoom siv rwb thaiv tsev yuav tsum ua kom tau raws li cov hluav taws xob tsis sib xws ntawm coaxial cables. Daim thaiv npog txheej yog tsim ntawm cov hlau tsoo lossis cov ntawv txheeb uas ua raws li kev sib kis tus kab mob thiab ECM cov lus qhia tshwj xeeb. Lub inner inerer ntawm daim thaiv thaiv txheej yog 6.15mm thiab cov taub sab hauv yog 8.28mm. Polyvinyl chloride (xws li polyvinyl chloride) lossis cov ntaub ntawv zoo sib xws yog siv ua cov khoom sib cais.
Lub ntsiab tsis:
(1) Ib lub Circuit Court hauv ib txheej kev saib xyuas lossis daim thaiv npog.
(2) Luv Circuit Court ntawm cov neeg xyuas kev coj thiab thaiv txheej.
(3) tus txiv neej pib ua si.
(4) Luv luv ntawm kev tiv thaiv cov pob qij txha.
