Kev ua tau zoo specifications rau kev tshaj tawm thiab txuas kho vajtse

Nyob rau hauv cov txheej txheem cabling, cov khoom siv cabling feem ntau suav nrog: cov khoom xa tawm, kev sib kis xov xwm, kev sib txuas lus, qhov (socket boards), trunking, thiab pipelines.
1) Media
Muaj feem ntau twisted khub thiab optical fiber ntau, thiab nyob rau hauv Suav teb, txoj kev sib tw twisted khub thiab optical fiber ntau yog siv. Fiber optic feem ntau yog siv rau cov ntaub ntawv zoo sib kis thiab kev sib txuas ntawm caj qaum. Raws li cov teeb liab kis tau tus mob, nws tuaj yeem muab faib ua ob hom: multimode fiber ntau thiab ib hom fiber ntau, nrog rau txoj kab uas hla ntawm 62.5/125 micrometers. Ntau hom fiber ntau yog siv rau kev sib txuas kab rov tav, thiab ib hom fiber ntau yog siv rau cov pob txha ntsug.
2) Connector thiab socket
Yuav tsum muaj tsawg kawg yog ob lub qhov (socket) cov ntaub ntawv hauv txhua qhov chaw ua haujlwm, ib qho rau lub suab thiab ib qho rau cov ntaub ntawv. Cov pins sib txuas rau cov qhov (socket) yog: 1 & 2, 3 & 6, 4 & 5, 7 & 8.
Tuam Tshoj pib siv cov txheej txheem cabling lub tswv yim ntawm North America, uas siv txoj kev sib tw cabling ntawm cov khub twisted thiab kaum fibers. Twisted khub cables muab faib ua ob hom: shielded thiab unshielded.
Lub shielding system yog tsim los xyuas kom meej cov kis tau tus mob ntawm lub system nyob rau hauv kev cuam tshuam ib puag ncig. Kev tiv thaiv kev cuam tshuam muaj xws li ob yam, uas yog, lub peev xwm ntawm lub cev tiv thaiv kev cuam tshuam sab nraud ntawm electromagnetic thiab lub peev xwm ntawm lub cev nws tus kheej kom tawm electromagnetic cuam tshuam. Nyob rau tom kawg, Tebchaws Europe tau dhau Electromagnetic compatibility test standard EMC specification. Txoj kev dav dav kom ua tiav kev tiv thaiv yog los qhwv cov hlau thaiv txheej txheej txheej txheej ntawm cov khoom siv sib txuas los lim tawm cov tsis tsim nyog electromagnetic tsis. Tam sim no muaj ob lub qauv sib txawv ntawm cov xov hlau thaiv kev xaiv, STP thiab S-STP.
Lub shielding txheej ntawm lub shielding system yuav tsum tau grounded. Thaum qhov zaus qis dua 1MHz, ib qho chaw hauv av txaus. Thaum qhov zaus siab dua 1MHz, EMC ntseeg tias nws yog qhov zoo tshaj plaws rau hauv av ntawm ntau qhov chaw. Qhov kev xyaum ib txwm yog rau hauv av ntawm ib feem kaum ntawm lub wavelength, thiab qhov ntev ntawm cov xaim hauv av yuav tsum tsawg dua ib feem kaum ntawm lub wavelength. Yog tias cov av tsis zoo (xws li kev tiv thaiv hauv av ntau dhau, qhov tsis sib xws ntawm qhov thaiv qhov muaj peev xwm, thiab lwm yam), muaj peev xwm sib txawv yuav raug tsim, uas yuav ua rau muaj kev cuam tshuam thiab zais kev phom sij kom ntseeg tau tias kev ua haujlwm ntawm kev tiv thaiv.
Nws yog ib qho tsim nyog sau cia tias cov cables thaiv tsis tuaj yeem txiav txim siab tag nrho EMC kev ua haujlwm ntawm lub cev. Qhov kev ncaj ncees ntawm lub shielding system nyob ntawm qhov tsis muaj zog tshaj plaws hauv lub cev. Xws li jumper panels, connector ntaub ntawv ports, pab kiag li lawm, thiab lwm yam. Yog li ntawd, yog hais tias lub shielding hlau tawg thaum lub sij hawm installation, nws yog ib tug txaus ntshai link nyob rau hauv sub shielding system.
Cov saum toj no yog txhua yam hais txog kev tsim qhov tseem ceeb ntawm kev xaim hluav taws xob zoo. Qhov tseeb, yog tias cov kab rov tav hloov pauv, nws yuav ua rau lub tsev puas tsuaj thiab cuam tshuam rau kev zoo nkauj tag nrho. Yog li ntawd, nyob rau hauv kev tsim cov kab rov tav kab, peb sim xaiv cov qib siab dua cov kab hluav taws xob thiab cov khoom sib txuas kom luv luv lub voj voog.
