Dab tsi yog cov kev ntsuas rau kev tiv thaiv xob laim ntawm optical cables

Nrog rau txoj kev loj hlob ntawm lub network, optical fiber, raws li ib tug nruab nrab siv rau kev xa cov ntaub ntawv nyob rau hauv kev sib txuas lus cabling systems, tau ua nrov nrov vim nws qhov zoo xws li cov kis tau tus mob siab thiab nyob deb. Raws li paub zoo, fibers optical tsis yog tus coj thiab tuaj yeem tiv thaiv los ntawm kev cuam tshuam tam sim no. Optical cables kuj muaj kev tiv thaiv zoo. Cov khoom siv hlau hauv cov khoom siv kho qhov muag muaj qhov muaj txiaj ntsig zoo ntawm cov rwb thaiv tsev rau hauv av, ua rau nws nyuaj rau cov xob laim nkag mus rau hauv lub cable. Txawm li cas los xij, vim yog cov tub ntxhais tseem ceeb ntawm lub cable, tshwj xeeb tshaj yog cov tub rog txheej ntawm cov kab ncaj qha faus, nws tuaj yeem raug hlawv lossis puas thaum cov kab hluav taws xob raug ntaus los ntawm xob laim. Ntawm no peb yuav piav qhia ntxaws txog cov kev ntsuas tseem ceeb rau kev tiv thaiv xob laim ntawm optical cables thiab fibers hauv kev tsim kho kev xaim hluav taws xob.
Ntsuas 1: Rau kev tiv thaiv xob laim ntawm cov kab hluav taws xob ncaj qha: ① Txoj hauv kev hauv av hauv zos, cov hlau hauv cov khoom siv kho qhov muag yuav tsum tau txuas nrog ntawm cov pob qij txha, kom cov tub ntxhais ntxiv dag zog, txheej txheej tiv thaiv ya raws, thiab cov cuab yeej ntawm cov khoom siv kho qhov muag. cable tseem txuas nrog. ② Raws li cov kev cai ntawm YDJ14-91, txheej txheej tiv thaiv ya raws, txheej armor, thiab cov tub ntxhais ntxiv dag zog ntawm qhov sib koom ua ke ntawm cov khoom siv kho qhov muag yuav tsum tau txiav hluav taws xob thiab tsis siv hauv av. Lawv yuav tsum tau insulated los ntawm hauv av, uas yuav zam tau cov tsub zuj zuj ntawm induced xob laim tam sim no nyob rau hauv lub kho qhov muag cable thiab zam cov kev taw qhia ntawm xob laim tam sim no nyob rau hauv av mus rau hauv lub kho qhov muag cable los ntawm lub grounding ntaus ntawv vim qhov sib txawv ntawm impedance ntawm lub xob laim tiv thaiv kua. kab thiab grounding Circuit Court ntawm optical cable hlau Cheebtsam.
Ntsuas 2: Rau cov khoom siv hluav taws xob siv hluav taws xob: Cov kab hluav taws xob hluav taws xob yuav tsum tau txuas nrog hluav taws xob thiab hauv av txhua 2 km. Thaum lub sij hawm hauv av, lawv tuaj yeem ncaj qha hauv av lossis hauv av los ntawm cov khoom siv tiv thaiv kev tiv thaiv kom tsim nyog. Cov xaim hluav taws xob no muaj kev tiv thaiv zoo ntawm cov hlau hauv av.
Ntsuas 3: Tom qab qhov kho qhov muag 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 tam sim no xob laim sai, muab kev tiv thaiv. Ncaj nraim faus optical cables nrog armor txheej thiab cov tub ntxhais muaj zog yog siv, thiab sab nrauv yog PE (polyethylene) sheath, uas tuaj yeem tiv thaiv corrosion thiab nas tom.
