Cov txheej txheem hlau thiab cov khoom lag luam cable tuaj yeem muab faib feem ntau muab faib ua plaub ntu:tus saib xyuas, Rwb thaiv tsev cov khaubncaws sab nraud, daim thaiv thaiv thiab tiv thaiv txheej, nrog rau tag nrho cov khoom siv thiab lub kaum ntswj. Raws li kev siv cov kev siv thiab kev siv cov xwm txheej, xws li cov khoom siv hluav taws xob sib xyaw, kev tiv thaiv hluav taws xob (piv txwv li, rwb thaiv tsev cua) kom muaj kev nyab xeeb.
1. Caj
Cov neeg saib xyuas yog cov khoom siv tseem ceeb tshaj plaws thiab kev tsis tseem ceeb tshaj plaws rau kev sib kis hluav taws xob cov ntaub ntawv hluav taws xob lossis hluav taws xob cov ntaub ntawv hauv cov khoom lag luam. Cores cov Cores, feem ntau xa mus rau cov cornes xo cov cornes uas zoo li tooj liab tau siv ntau xyoo dhau los ua haujlwm tau ua haujlwm.
2. Rwb thaiv tsev txheej
Cov khoom siv no hauv lub hnab ntim cov neeg coj tus cwj pwm, muab rwb thaiv tsev hluav taws xob. Lawv xyuas kom meej tias tam sim no lossis hluav taws xob / siv hluav taws xob / kho qhov muag tsis sib xws tsuas yog taug kev raws tus neeg kos npe thiab tsis sab nraud. Rwb thaiv tsev cov khaubncaws sab nraud povtseg tswj tau lub peev xwm (piv txwv li, kev voltage) ntawm tus neeg xyuas coj ntawm cov neeg saib xyuas thiab kev nyab xeeb sab nraud rau cov khoom thiab tib neeg.
Cov txheej txheem thiab cov khaubncaws ntawm cov txheej txheem thiab cov khaubncaws sab nraud povtsuaj yog ob lub hauv paus tseem ceeb rau cov khoom lag luam (tsuas yog rau cov xov hlau (tshwj tsis yog cov xov tooj liab).
3. Cov khaubncaws sab nraud povtseg tiv thaiv
Hauv kev teeb tsa ntau puag ncig thaum lub sijhawm teeb tsa thaum lub sijhawm ua haujlwm, xaim thiab cov khoom lag luam xaim yuav tsum muaj cov khoom uas muaj kev tiv thaiv, tshwj xeeb tshaj yog rau cov txheej txheem rwb thaiv tsev. Cov khoom siv no yog hu ua kev tiv thaiv txheej txheem.
Vim tias cov ntaub ntawv rwb thaiv tsev yuav tsum muaj hluav taws xob hluav taws xob rwb thaiv tsev zog, lawv yuav tsum tau muaj kev coj dawb huv nrog cov ntsiab lus impurity tsawg. Txawm li cas los xij, cov ntaub ntawv no feem ntau tsis tuaj yeem muab kev tiv thaiv los ntawm lwm cov kev teeb tsa sab nraud (piv txwv li, roj, phom sij, thiab phom sij rau phom sij). Cov kev xav tau no yog daws los ntawm ntau yam kev tiv thaiv ntau txheej txheej txheej.
Rau cov cables tsim tshwj xeeb rau cov chaw nyob sab nraud (xws li cov khoom siv hluav taws xob tsis muaj zog, muaj kev xav tau rau txheej tiv thaiv kev tiv thaiv raws li kev tiv thaiv kev tiv thaiv.
4. Daim thaiv
Nws yog ib qho kev tivthaiv hauv cov khoom lag luam cable uas cais cov khoom siv hluav taws xob tsis pub dhau lub cable los ntawm cov chaw siv hluav taws xob sab nraud. Txawm nyob ntawm cov hlau hlau sib txawv lossis cov pab pawg nyob rau hauv cov khoom lag luam cable, kev sib deev yog qhov tsim nyog. Daim thaiv npog yuav tuaj yeem piav qhia tias yog "kev sib cais hluav taws xob hauv hluav taws xob."
Tau ntau xyoo, kev lag luam tau txiav txim siab daim thaiv npog txheej uas yog ib feem ntawm cov txheej txheem tiv thaiv txheej txheem. Txawm li cas los xij, nws tau npaj siab tias nws yuav tsum tau txiav txim siab ua ib qho sib txawv. Qhov no yog vim tias txoj haujlwm ntawm daim thaiv npog txheej tsis yog rau cov khoom siv hluav taws xob sab nraud, tab sis kuj tseem yuav ua rau sab nraud ntawm cov khoom siv cable los ntawm kev sib txuas hluav taws xob. Cov kev xav tau no txawv ntawm cov txheej tiv thaiv txheej txheem ib txwm muaj ua haujlwm. Ib qho ntxiv, daim thaiv thaiv txheej tsis yog tsuas yog teeb sab nraud hauv cov khoom tab sis kuj tau muab tso ntawm txhua khub xaim lossis ntau khub hauv cable. Tshaj li kaum xyoo dhau los, vim kev txhim kho kev nthuav dav ntawm cov ntaub ntawv sib kis tau siv cov xov hlau thiab cov cable Qhov kev nkag siab tias daim npog txheej thaiv yog qhov tseem ceeb ntawm cov khoom lag luam cable tau ua rau dav.
5. Kev sau qauv
Ntau cov xaim xaim thiab cov khoom lag luam cable muaj ntau cov tub ntxhais, xws li feem ntau ntawm cov hluav taws xob tsawg (haum rau peb-theem Tom qab sib txuas cov pob cores los yog cov khub xaim rau hauv ib qho cable (lossis ntau zaus cov qauv thiab cov khoob loj nyob nruab nrab lossis cov khub xaim. Yog li ntawd, ib txoj kev sau ua ke yuav tsum tau koom ua ke thaum sib dhos cable. Lub hom phiaj ntawm cov qauv no yog txhawm rau tswj cov cheeb hauv lub taub hauv coiling, yooj yim qhwv thiab sheath extrusion. Ntxiv mus, nws ntseeg tau Cable kev ruaj ntseg thiab kev faib tawm sab hauv, ncab, ncab thaum lub sijhawm tsim khoom thiab khoov) kom tiv thaiv kev puas tsuaj rau cov cable sab hauv.
Yog li ntawd, txawm hais tias cov qauv puv yog ib qho kev ntsuas, nws yog qhov tsim nyog. Cov ncauj lus kom ntxaws txog cov khoom xaiv thiab tsim qauv ntawm cov qauv no.
Tsoos ib txwm siv hlau thiab cable cov khoom lag luam feem ntau cia siab rau txheej txheem tiv thaiv ntawm cov rog sab nraud lossis qhov nro tshwm sim los ntawm lawv tus kheej qhov hnyav. Cov qauv ntaub ntawv raug suav nrog cov kab xev hlau dhos (xws li siv 8 hli tuab hlau xov hlau, sib ntswg txheej, rau submarine cable). Txawm li cas los xij, nyob rau hauv cov fiber ntau cov xaim hluav taws xob, los tiv thaiv cov fiber ntau lub zog, tiv thaiv kev sib kis me me thiab cov qauv tshwj xeeb yog sib xyaw rau hauv cov qauv cable. Piv txwv li, hauv cov xov tooj ntawm tes xov tooj ntawm tes lossis cov kab xev tooj liab nyob ib ncig ntawm cov txheej txheem insulating, uas cov hluavtaws fiber ua ua lub kaum tawm. Zuag qhia tag nrho, nyob rau hauv kev txhim kho cov khoom tshwj xeeb me me thiab hloov tau cov khoom lag luam me me uas yuav tsum muaj ntau txoj hlua khi thiab twists, lub luag haujlwm tseem ceeb.
