Kev xaiv cov kab hluav taws xob tsim nyog rau cov cheeb tsam nyuaj xws li subways, siab - chaw nres tsheb ciav hlau ceev, thiab tshav dav hlau yuav tsum muaj kev nkag siab zoo ntawm cov qauv kev sib kis thiab kev tiv thaiv ib puag ncig. Nyob rau hauv cov high - tsheb thauj mus los hubs, cabling yog lub hauv paus paj hlwb uas txhawb txhua yam ntawm daim pib mus rau kev ruaj ntseg soj ntsuam. Raws li Shanghai siab- thev naus laus zis kev lag luam, peb tau siv ntau xyoo los ua kom cov rwb thaiv tsev zoo tshaj plaws thiab tiv thaiv peb cov tooj liab thiab fiber ntau optic cables kom ntseeg tau tias lawv ua tau raws li qhov xav tau nruj ntawm kev txav mus los niaj hnub hauv nroog. Thaum ntsuas cov kab hluav taws xob, ib qho yuav tsum xub saib nws cov qeb- xws li Cat6 lossis Cat6A- uas txiav txim siab qhov bandwidth thiab ceev peev xwm. Txawm li cas los xij, dhau qhov nrawm, lub cev ua haujlwm ntawm cov khoom siv lub tsho yog qhov tseem ceeb. Peb cov kab hluav taws xob tau tsim los ua cov nplaim hluav taws- rov qab thiab qis- pa taws xoom- halogen (LSZH), qhov tseem ceeb tshaj plaws rau hauv av subway tunnels thiab tshav dav hlau terminals uas pej xeem kev nyab xeeb yog qhov tseem ceeb tshaj plaws.
Cov xov xwm kev lag luam hais txog cov khoom siv raw qhia txog qhov kev hloov pauv tseem ceeb mus rau siab -purity oxygen- tooj liab dawb, uas txo qis cov teeb liab attenuation nyob ntev. Raws li Shanghai thev naus laus zis-raws li kev lag luam me thiab nruab nrab- loj, peb muab cov ntaub ntawv qib siab - qib no rau hauv peb cov kab ntau lawm kom ntseeg tau tias peb cov "Cable" series muab lub hauv paus ruaj khov rau "npaj loj" ntawm cov kev pabcuam kev siv tshuab. Piv txwv li, hauv peb txoj kev xaav tau zoo nrog Beike Coffee Machines hauv tshav dav hlau, kev ruaj ntseg ntawm lub hauv paus network cable ua kom ntseeg tau tias txhua qhov kev hloov pauv thiab cov xwm txheej tshuab hloov pauv tsis muaj lag luam. Cov kauj ruam siv rau cov cables no suav nrog cov txheej txheem txiav tawm meej; yog tias qhov sib tw ntawm cov khub sab hauv raug cuam tshuam ntau dhau thaum lub sijhawm stripping, tus ntoo khaub lig- tham yuav nce ntxiv, ua rau pob ntawv poob. Peb cov kev muag khoom loj loj thiab kev pabcuam network muab kev pabcuam kev pabcuam los xyuas kom meej tias txawm tias lub cable raug teeb tsa hauv lub Hoobkas chaw ua si lossis xinesmas, lub teeb liab kev ncaj ncees tseem zoo tag nrho. Los ntawm kev xaiv cov khoom lag luam los ntawm Shanghai tshwj xeeb thiab kev lag luam tshiab, cov tswv lag luam hauv cov tuam tsev ua lag luam thiab tsoomfwv cov chaw tuaj yeem ntseeg tau tias lawv cov pob txha kev sib txuas lus tau tsim los mus rau qhov kawg, txhawb kev siab - cov ntaub ntawv ceev ntawm lub neej yav tom ntej.
