Cov qauv kev lag luam rau fiber ntau optic cables

Nyob rau hauv cov nqe lus ntawm kev lag luam cov qauv, kev tsim thiab kev ntsuam xyuas ntawm fiber optic cables ua raws li cov qauv nruj thiab specifications. Cov koom haum thoob ntiaj teb xws li International Telecommunication Union (ITU) thiab International Electrotechnical Commission (IEC) tau tsim cov txheej txheem rau fiber ntau optic cables, suav nrog hom fiber ntau, kev ua haujlwm tsis zoo, thiab cov qauv kev sim. Cov qauv no xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm fiber ntau optic cables, muab cov neeg siv kev xaiv txhim khu kev qha.

 

Tam sim no, tus nqi ntawm fiber ntau optic cables txawv nyob ntawm seb yam xws li hom, specifications, thiab hom. Feem ntau, tus nqi ntawm ib qho tib si - hom fiber ntau optic cables nyob ntawm ob peb yuan mus rau kaum ntawm yuan ib 'meter', thaum multimode fiber optic cables kuj pheej yig dua. Rau qhov ntev - nrug, siab - fiber ntau optic cables, tus nqi yuav siab dua. Txawm li cas los xij, zuag qhia tag nrho, nrog kev nce qib kev thev naus laus zis txuas ntxiv thiab nce kev sib tw ua lag luam, tus nqi ntawm fiber ntau optic cables tau maj mam ua kom tsim nyog, muab cov neeg siv ntau txoj kev xaiv.

 

Thaum xaiv cov fiber ntau optic cables, cov neeg siv yuav tsum xav txog lawv cov kev xav tau tiag tiag thiab daim ntawv thov scenarios. Piv txwv li, rau cov ntawv thov uas xav tau ntev - kis tau tus mob nyob deb, ib zaug - hom fiber ntau optic cables nrog qis attenuation coefficients thiab siab bandwidth yuav tsum raug xaiv; thaum luv-nruab deb, qis- daim ntawv thov ceev, multimode fiber optic cables tuaj yeem xaiv los txo cov nqi. Tsis tas li ntawd, cov neeg siv kuj yuav tsum tau them sai sai rau qhov kev ua tau zoo ntawm cov fiber ntau optic cables, xws li cov ntaub ntawv sheath thiab tensile lub zog, kom ntseeg tau tias lawv tuaj yeem ua tau raws li cov kev xav tau ntawm kev siv tswv yim.
