Raws li peb txhua tus paub, fiber ntau optical tsis yog-conductive thiab muaj peev xwm tiv thaiv los ntawm inrush tam sim no, thiab kho qhov muag cable kuj muaj kev tiv thaiv zoo, cov khoom siv hlau hauv optical cable muaj cov nqi hluav taws xob siab rau hauv av, thiab cov hluav taws xob tsis zoo. yooj yim nkag mus rau qhov kho qhov muag cable. Txawm li cas los xij, vim hais tias cov kab hluav taws xob kho qhov muag muaj cov tub ntxhais muaj zog, tshwj xeeb tshaj yog cov kab hluav taws xob ncaj qha faus rau hauv qhov muag muaj cov txheej txheem armor, thaum cov kab hluav taws xob kho qhov muag raug cuam tshuam los ntawm xob laim, cov kab hluav taws xob kho qhov muag kuj tuaj yeem hlawv lossis puas. Yog li, peb yuav ua li cas tiv thaiv xob laim puas hauv cov qauv cabling?

Nrog rau txoj kev loj hlob ntawm lub network, optical fiber ntau yog siv los ua ib qho nruab nrab rau cov ntaub ntawv kis tau tus mob nyob rau hauv lub integrated thaiv system, vim hais tias nws muaj qhov zoo ntawm cov kis tau tus mob loj npaum li cas thiab nyob deb deb, nws yog ntau thiab ntau siv los ntawm cov neeg. Niaj hnub no, peb yuav piav qhia meej txog cov kev ntsuas tseem ceeb rau kev tiv thaiv xob laim ntawm optical cables thiab optical fibers nyob rau hauv kev tsim kho ntawm kev sib txuas cov phiaj xwm.

1. Kev tiv thaiv xob laim rau cov kab hluav taws xob ncaj nraim: ① Hauv chaw ua haujlwm hauv av, cov hlau hauv cov khoom siv kho qhov muag yuav tsum tau txuas nrog ntawm cov pob qij txha, kom cov tub ntxhais muaj zog, cov txheej txheem ya raws, thiab cov cuab yeej cuab tam ntawm ntu relay. ntawm optical cable yog khaws cia txuas. ② Raws li cov kev cai ntawm YDJ14-91, cov txheej txheem ya raws, txheej armor thiab reinforcing core ntawm qhov kho qhov muag cable sib koom yuav tsum tau muab hluav taws xob sib txuas, thiab lawv tsis yog hauv av, thiab lawv tau insulated los ntawm hauv av, uas tuaj yeem zam qhov sib txuam ntawm induced xob laim tam sim no nyob rau hauv optical cable. Nws kuj tseem tuaj yeem zam tau tias xob laim tam sim no hauv ntiaj teb tau nkag mus rau hauv cov khoom siv kho qhov muag los ntawm cov khoom siv hauv av vim qhov sib txawv ntawm impedance ntawm kev tiv thaiv xob laim ntawm cov xaim hluav taws xob thiab cov khoom siv hlau ntawm cov khoom siv kho qhov muag rau hauv av.

2.Rau cov khoom siv hluav taws xob siv hluav taws xob: cov xov hluav taws xob siv hluav taws xob yuav tsum tau txuas nrog hluav taws xob thiab hauv av txhua 2km. Thaum grounding, nws tuaj yeem raug grounded ncaj qha lossis los ntawm cov khoom siv tiv thaiv kev tiv thaiv zoo. Nyob rau hauv no txoj kev, lub ncua kev kawm ntawv hlau muaj kev tiv thaiv ntawm lub overhead av hlau.

3. Tom qab lub optical cable nkag mus rau hauv lub thawv davhlau ya nyob twg, lub thawv davhlau ya nyob twg yuav tsum tau muab tso rau hauv av. Tom qab cov hluav taws xob tam sim no nkag mus rau hauv cov hlau txheej ntawm cov khoom siv kho qhov muag, lub hauv paus ntawm lub thawv davhlau ya nyob twg tuaj yeem tso tawm cov hluav taws xob tam sim no sai thiab ua lub luag haujlwm tiv thaiv. Cov kab hluav taws xob faus ncaj qha muaj cov txheej txheem armor thiab cov tub ntxhais muaj zog, thiab lub plhaub sab nraud yog PE (polyethylene) sheath, uas tuaj yeem tiv thaiv corrosion thiab nas tom.
