ADSS (All-Dielectric Self-Supporting) thiab OPGW (Optical Ground Wire) yog ob hom fiber optic cables siv rau hauv cov kab xa xov overhead, txhua tus muaj nws tus kheej cov yam ntxwv thiab qhov zoo:

ADSS (All-Dielectric Self-Supporting):

ADSS cables tau tsim los kom ntsia tau rau ntawm cov kab xa hluav taws xob uas twb muaj lawm yam tsis tas yuav muaj cov qauv txhawb nqa ntxiv (xws li cov xov hlau xa xov lossis cov khoom siv hlau muaj zog).

Lawv yog ua los ntawm cov ntaub ntawv dielectric, feem ntau yog fiberglass lossis aramid yarns, uas muab ob qho tib si hluav taws xob rwb thaiv tsev thiab lub zog kho tshuab.

ADSS cov cables yog lub teeb yuag, yooj yim rau kev teeb tsa, thiab tiv taus kev cuam tshuam hluav taws xob, ua rau lawv haum rau kev teeb tsa ntev thiab thaj chaw uas muaj kev cuam tshuam hluav taws xob siab.

Lawv feem ntau siv rau hauv cov cheeb tsam uas muaj cov dej khov nruab nrab mus rau siab, vim lawv muaj cov yam ntxwv qis thiab tuaj yeem tiv taus cov xwm txheej ib puag ncig hnyav.

OPGW (Optical Ground Wire):

Cov xov hlau OPGW raug tsim los ntawm cov fibers optical embedded nyob rau hauv lub plawv ntawm ib qho av hlau siv rau hauv cov kab xa xov overhead.

Lub zog hlau ntawm OPGW muab ob qho tib si kev ua hluav taws xob thiab kev txhawb nqa kho tshuab rau lub cable, thaum cov fibers optical hauv lub hauv paus xa cov ntaub ntawv teeb liab.

Cov xov hlau OPGW muaj kev sib xyaw ua ke ntawm kev siv hluav taws xob thiab kev xa cov ntaub ntawv, ua rau lawv haum rau cov ntawv thov uas xav tau ob qho tib si, xws li kev sib txuas lus hluav taws xob.

Lawv muab cov peev xwm bandwidth siab thiab feem ntau siv rau hauv cov haujlwm tseem ceeb uas kev sib txuas lus txhim khu kev qha yog qhov tseem ceeb, xws li hauv cov kab ke ntse thiab cov kab hluav taws xob siab.

Hauv kev xaus lus, ADSS cables yog cov cables fiber optic uas txhawb nqa tus kheej, dielectric uas tsim nyog rau kev teeb tsa ntawm cov kab xa xov uas twb muaj lawm, thaum OPGW cables sib xyaw cov fibers optical rau hauv lub hauv paus ntawm cov xov hlau hauv av, muab ob qho tib si hluav taws xob hauv av thiab cov peev xwm xa cov ntaub ntawv. Kev xaiv ntawm ADSS thiab OPGW nyob ntawm cov yam xws li qhov yuav tsum tau teeb tsa, cov xwm txheej ib puag ncig, thiab cov kev xav tau tshwj xeeb ntawm daim ntawv thov.
