海报 2- 未切割

Cov txheej txheem cabling yog kev sib xyaw ua ke ntawm txoj kev crimping, qauv qauv, lub hnub qub topology, thiab qhib nta. Nws suav nrog ntau lub subsystems:

Servers:

Servers tswj cov peev txheej thiab muab kev pabcuam rau cov neeg siv. Lawv feem ntau categorized li cov ntaub ntawv servers, database servers, thiab daim ntawv thov servers. Cov servers muaj kev xav tau ntau dua rau kev ruaj ntseg, kev ruaj ntseg, thiab kev ua haujlwm zoo piv rau cov PCs niaj hnub. Yog li ntawd, lawv cov khoom siv kho vajtse, xws li CPU, chipset, nco, disk systems, thiab networking, txawv ntawm cov qauv PCs.

Routers:

Kuj tseem hu ua cov khoom siv rooj vag, routers txuas cov kev sib txuas lus sib cais. Cov kev sib txuas lus sib txuas lus no sawv cev rau ib leeg network lossis subnets. Thaum cov ntaub ntawv xav tau xa los ntawm ib lub subnet mus rau lwm qhov, routers siv lawv txoj haujlwm ua haujlwm kom ua tiav txoj haujlwm no. Routers txiav txim qhov chaw nyob hauv network thiab xaiv IP paths. Lawv tsim kom muaj kev sib txuas yooj yim hauv ntau lub network ib puag ncig, tso cai rau cov ntaub ntawv sib txawv ntawm cov ntaub ntawv sib txawv thiab cov txheej txheem nkag mus rau kev tshaj tawm los txuas ntau yam subnets. Routers tsuas yog lees txais cov ntaub ntawv los ntawm cov chaw nres tsheb lossis lwm lub routers thiab koom nrog txheej txheej network raws li cov khoom sib txuas.

Fiber Optic Transceivers:

Fiber optic transceivers pauv luv luv-ntu twisted-pair hluav taws xob teeb liab nrog rau qhov ntev-ntev optical signals hauv Ethernet kis xov xwm. Lawv kuj raug hu ua optical-electrical converters. Cov khoom siv no feem ntau siv rau hauv qhov chaw ua haujlwm hauv network uas Ethernet cables tsis tuaj yeem npog qhov yuav tsum tau sib kis, xav tau kev siv fiber ntau optics. Lawv feem ntau muab tso rau ntawm cov txheej txheem nkag mus rau hauv kev sib txuas hauv nroog loj hauv cheeb tsam (MANs) thiab ua lub luag haujlwm tseem ceeb hauv kev txuas cov kab kawg-mais fiber ntau rau MANs thiab sab nraud.

Fiber Optics:

Fiber optics, abbreviated li optical fibers, yog ua los ntawm iav los yog yas thiab ua hauj lwm raws li cov khoom siv teeb pom kev zoo. Lub hauv paus ntsiab lus kis tau tus mob yog nyob ntawm "tag nrho cov kev xav sab hauv" ntawm lub teeb. Lub tswv yim ntawm kev siv cov fibers optical rau kev sib txuas lus yog thawj zaug los ntawm Hong Kong Suav University Thawj Tswj Hwm Kao Kuen (Charles K. Kao) thiab George A. Hockham. Kao tau txais txiaj ntsig Nobel nqi zog hauv Physics hauv 2009 rau lub tswv yim no.

Optical Cables:

Optical cables yog tsim los ua kom tau raws li kev kho qhov muag, kho qhov muag, lossis ib puag ncig kev ua tau zoo. Lawv siv ib los yog ntau dua optical fibers muab tso rau hauv kev tiv thaiv sheaths raws li qhov nruab nrab kis tau tus mob thiab yuav siv tau ib tug neeg los yog nyob rau hauv pab pawg neeg raws li kev sib txuas lus cable Cheebtsam. Cov khoom tseem ceeb ntawm cov khoom siv kho qhov muag muaj xws li cov khoom siv kho qhov muag (pob tshab iav los yog cov yas filaments), cov hlau txuas ntxiv, cov khoom ntim, thiab cov ntaub qhwv sab nraud. Raws li qhov yuav tsum tau ua, cov khoom siv ntxiv xws li cov khaubncaws sab nraud povtseg, cov khaubncaws sab nraud povtseg, thiab insulated hlau conductors yuav suav nrog.

Patch Panels:

Patch panels yog cov khoom siv modular siv los tswj cov ntaub ntawv pem hauv ntej-kawg cov ntsiab lus ntawm kev faib khoom kawg. Thaum cov ntaub ntawv cables (xws li Qeb 5e lossis Qeb 6) los ntawm cov ntsiab lus pem hauv ntej nkag mus rau hauv chav tsev, lawv thawj zaug txuas rau thaj chaw. Cov cables raug txiav mus rau cov modules nyob rau hauv lub thaj vaj huam sib luag, thiab tom qab ntawd jumper cables (siv RJ45 interfaces) txuas lub vaj huam sib luag rau cov keyboards. Zuag qhia tag nrho, thaj vaj huam sib luag ua haujlwm ua cov khoom siv tswj hwm. Yog tsis muaj thaj vaj huam sib luag, txuas ncaj qha mus rau pem hauv ntej-kawg cov ntaub ntawv cov ntsiab lus rau cov keyboards yuav tsum tau rewiring yog tias teeb meem cable tshwm sim.

Uninterruptible Power Supplies (UPS):

UPS systems txuas cov roj teeb uas siv tau (feem ntau cov roj teeb uas tsis muaj cov hmoov lead-acid) mus rau chav tsev loj. Los ntawm inverters thiab lwm yam Circuit Court modules, UPS systems hloov direct tam sim no (DC) los ntawm cov roj teeb rau hauv alternating tam sim no (AC) rau siv thaum fais fab tuag. Lawv feem ntau yog siv los muab cov khoom siv hluav taws xob ruaj khov, tsis muaj kev cuam tshuam rau tib lub khoos phis tawj, khoos phis tawj network, lossis lwm yam khoom siv hluav taws xob (xws li solenoid li qub thiab lub tshuab xa hluav taws xob). Thaum lub hwj chim hluav taws xob zoo li qub, UPS ruaj khov thiab muab lub zog rau lub nra. Thaum lub sij hawm fais fab cuam tshuam (kev tsis sib haum xeeb), UPS tam sim ntawd hloov mus rau lub roj teeb lub zog, muab 220V AC kom muaj kev ua haujlwm zoo thiab tiv thaiv ob qho tib si kho vajtse thiab software ntawm cov khoom thauj. UPS cov khoom siv feem ntau muaj kev tiv thaiv ob qho tib si siab thiab tsis tshua muaj hluav taws xob.

Patch Panels:

Patch panels yog siv rau hauv thaj chaw ua haujlwm cabling subsystem thiab tsim nyog rau kev txhim kho ntau hom modules. Lawv lub hom phiaj tseem ceeb yog kom ruaj ntseg modules thiab tiv thaiv cable terminations ntawm cov ntaub ntawv outlets, ua raws li ib tug hom ntawm cov tshuaj ntsuam los yog ntaub thaiv npog. Txawm hais tias thaj vaj huam sib luag tsis cuam tshuam rau qhov kev ua tau zoo, lawv yog ib qho ntawm ob peb qhov pom ntawm phab ntsa hauv tag nrho cov kab ke. Lawv cov kev ua tau zoo thiab kev zoo nkauj ncaj qha cuam tshuam rau tag nrho cov txiaj ntsig ntawm kev teeb tsa cabling.

Hloov:

Cov keyboards yog cov khoom siv hauv network siv rau kev xa xov xa mus. Lawv muab cov teeb liab tshwj xeeb ntawm ob lub network nodes txuas nrog rau kev nkag mus. Hom kev hloov pauv feem ntau yog Ethernet hloov. Lwm hom muaj xws li xov tooj lub suab keyboards thiab fiber optic keyboards.

Kev tsim cov cabling tsis yog hais txog cov xov hlau xwb - nws yog kev nqis peev hauv kev ua tau zoo, kev ntseeg siab, thiab kev npaj rau yav tom ntej.
