Raws li peb txhua tus paub tias lub teeb liab attenuation yog yam tsis muaj kev tiv thaiv thaum lub sij hawm xaim cable, Yog vim li cas rau qhov no yog sab hauv thiab sab nraud: sab hauv attenuation yog cuam tshuam nrog cov khoom siv fiber ntau, thiab sab nraud attenuation yog cuam tshuam nrog kev tsim kho thiab kev teeb tsa.Yog li ntawd, nws yuav tsum tau muab sau tseg tias:
1. Thawj qhov uas yuav tsum tau ua yog cov kws tshaj lij uas tau txais kev cob qhia nruj yuav tsum tau ua tiav qhov kev txiav tawm thiab kev saib xyuas ntawm cov khoom siv kho qhov muag, thiab ua haujlwm raws li kev tsim kho qhov muag fiber ntau.
2. Yuav tsum muaj cov qauv tsim thiab kev tsim ua tiav heev, kom kev tsim kho thiab kev tshuaj xyuas yav tom ntej yog yooj yim thiab txhim khu kev qha.Thaum lub sij hawm tsim kho, ceev faj tsis txhob muab lub optical cable nyob rau hauv lub siab hnyav los yog raug mob los ntawm cov khoom tawv;Nyob rau hauv tas li ntawd, lub traction quab yuam yuav tsum tsis txhob tshaj qhov siab tshaj plaws nteg nro.
3. Thaum lub fiber ntau optical yuav tig, nws txoj kab uas hla yuav tsum siab tshaj 20 npaug ntawm txoj kab uas hla ntawm cov fiber ntau nws tus kheej.Thaum cov khoom siv fiber ntau dhau los ntawm phab ntsa lossis hauv pem teb, cov yeeb nkab yas tiv thaiv nrog lub qhov ncauj tiv thaiv yuav tsum tau ntxiv, thiab cov yeeb nkab yuav tsum tau ntim nrog cov nplaim hluav taws kub.Ib qho nyiaj ntawm cov kav dej yas kuj tuaj yeem muab tso rau hauv lub tsev ua ntej.
4. Thaum siv cov khoom siv fiber ntau hauv cov pob txha caj qaum, tsawg kawg yog 6-core optical cable yuav tsum tau siv rau hauv cov hlua khi ntawm txhua lub hauv pem teb, thiab 12-core optical cable tuaj yeem siv rau kev siv qib siab.Qhov no yog xam los ntawm peb yam ntawm daim ntawv thov, thaub qab thiab muaj peev xwm nthuav dav.
5. Qhov tseem ceeb tshaj plaws rau qhov ntev-ntev fiber ntau tso yog xaiv txoj hauv kev uas tsim nyog.Ntawm no tsis tas yuav yog txoj hauv kev luv tshaj plaws yog qhov zoo tshaj plaws, tab sis kuj xyuam xim rau txoj cai siv av, muaj peev xwm ntawm erection lossis faus, thiab lwm yam.
