Nyob rau hauv lub network kev thaiv, nws yog qhov tseem ceeb ntawm kev siv ob hom kev teeb liab network sib kis: twisted pairing wire thiab optical fiber. Nws muaj ntau hom kev sib txig sib txawb ua ke. Tam sim no, muaj Cat5e, Cat6 thiab Cat7 hom. Feem ntau, cov xov tawb ntawm cov xovtooj muaj shielded thiab unshielded. Optical fibers yog muab faib ua ib hom fibers thiab multimode fibers.Let peb tham txog qhov zoo uas muaj nyob ntawm optical fiber ntau thiab Qeb 7 sib tw ua ke. 
Optical fiber ntau, tshwj xeeb tshaj yog ib hom optical cable, nws yuav siv rau kev sib kis ceev hauv high-speed, thiab muaj qhov zoo ntawm cov khoom ntim hluavtaws electromagnetic cuam tshuam, kev ntseeg siab, thiab kev txhawb nqa kev sib kis ntev. Nws yog ib qho kev sib txuas lus nruab nrab ntawm yav tom ntej hauv lub neej yav tom ntej, thiab nws txoj cai yog qhov tseem ceeb dua. Txawm li cas los, cov khoom siv kho qhov muag cable, cov ntaub ntawv thiab kev tshem tawm cov nqi kuj kim heev, thiab kev teeb tsa kuj yog qhov nyuaj, vim li ntawd nws yog qhov tsim rau ntev-ntev thiab muaj peev xwm tshaj plaws. Nyob rau tam sim no, 62.5 / 125μm multimode optical cable tau ua tus nruab nrab hauv nruab nrab hauv lub qhov thaiv lub cev, thiab nws daim ntawv thov nyob rau hauv kab rov tav nruab ntug tau dhau zuj zus.
Unshielded twisted khub UTP hlau yog cov khoom siv dav dav tshaj plaws hauv Suav teb. Nws yog tsim rau cov kev siv network nrog kev sib kis bandwidth hauv qab 250MHz thiab tsis muaj kev kawm tshwj xeeb. Nws qhov zoo yog kev ua haujlwm zoo, tsis muaj nqi, thiab tsim kho thiab tu. Tshooj 6 cabling systems tau mus txog cov kev txwv ntawm cov neeg khawm uas tsis muaj leej twg sib tw.
Cov txheej txheem txeem shielded twisted khub FTP hlau tau loj bandwidth thiab muaj zog tiv thaiv kev cuam tshuam, thiab muaj cov yam ntxwv ntawm cov pa uas tsis muaj qis thiab tsis muaj halogen. Hauv kev sib piv, tus xov tooj hlau shielded muaj nqi ntau dua thiab kev siv tus nqi tshaj cov xaim xaim, thiab txoj hlua khi txoj kab qis dua me ntsis. Hom siv no yog siv hauv Qeb 6 thiab yav dhau los tiv thaiv systems.
Tiv thaiv kom tsis txhob muaj tus kab mob ntawm tus kheej ua tw khoob rau STP hlau, txhua tus kab hlau muaj ib daim ntaub thaiv npog, plaub khi ntawm xov hlau ua ke thiab ib qho hlau npog npog, uas yog tus qauv ntawm Cat7 network cable. Nws yog tsim rau high-speed network applications, muab kev ruaj ntseg zoo heev, txhawb yav tom ntej tshiab daim ntaub ntawv, pab txhim kho lub xov tooj cua ntawm kev siv cov ntaub ntawv tam sim no, ua txhua yam ntaub ntawv los ntawm email mus rau multimedia yees duab rau hauv tib lub high-speed system .
Qhov ntxiv shielding ua rau Qeb 7 xaim muaj ib txoj kab loj loj. Cov nta no yuav tsum tau muaj kev saib xyuas tshwj xeeb thaum tsim txoj kev ua thiab kev txiav tawm, tawm hauv qhov chaw loj thiab qhov khoob loj loj
Ntxiv mus, vim nws cov qauv zoo heev thiab zoo siab bandwidth, ib tug raug xya-channel channel yuav txawm muab ib khub ntawm 862MHz bandwidth rau kev xa xov cable TV, cov teeb liab analog rau lwm nkawm, thiab ces tus thib peb. Plaub-xaim pauv kis ntawm high-speed LAN cov ntaub ntawv. Daim ntawv thov no zoo li lub sijhawm tam sim no, tiam sis tsis ntev dhau los no yuav siv los ntawm Qib 7 qhov system.
Piv rau fiber ntau-optic LANs, txoj kev sib kho Cat7 network cable muab qhov kev kawm zoo thiab bandwidth, tab sis tag nrho cov nqi tsuas yog ib feem ntawm cov fiber. Qee cov neeg xav tias fiber optic tshuab tuaj yeem nqa cov neeg muaj kabmob txaus rau cov neeg, thiab fiber optic cable ze rau tus nqi ntawm Qeb 7. Txawm li cas los xij, yog hais tias siv cov nqi ntawm cov neeg siv fiber ntau, cov keyboards qhov muag, thiab cov ntawv teev lus kho qhov muag tau zoo, qhov zoo ntawm qhov khoom muaj fiber ntau yuav poob sai sai.
