Tsev ONUs/ONTs thiab CPEs tseem siv davSCrau tus nqi thiab keeb kwm kev sib raug zoo vim li cas. Raws li cov cuab yeej hloov zuj zus mus, LC yuav dhau los ua ntau dua ntawm cov khoom siv hauv tsev, tab sis SC tseem muaj ntau heev niaj hnub no.
Qhov twg yog qhov txhim khu kev qha ntau dua: LC cov khoom sib txuas ceev lossis lub Hoobkas- txiav cov hlua txuas?
A:Hais txog kev ua haujlwm ntev -lub sijhawm ua haujlwm thiab ruaj khov,Hoobkas- txiav cov hlua txuas + fusion splicingmuaj kev ntseeg siab thiab tswj tau yooj yim dua hauv IL thiab RL. Fast connectors yog tsim nyog thaum nyob rau hauv - site tej yam kev mob yog txwv, rau kev siv thaum muaj xwm ceev los yog me me -scale retrofits. Thaum siv lawv, xyuas kom meej meej thiab tso cai rau cov paj ntau ntxiv hauv cov peev nyiaj txuas.
Kuv tuaj yeem qhia tau li cas yog tias LC connector puas thiab yuav tsum tau hloov?
A:Yog tias, tom qab kev tu kom zoo, IL tseem tseem ceeb heev, lossis OTDR cov kab mob qhia pom qhov txawv txav ntawm qhov chaw txuas thiab rov ua dua tshiab tsis pab, koj yuav tsum xav txog kev hloov lub connector lossis tag nrho cov kab txuas. Pom pom khawb, chips, lossis hlawv cov cim ntawm lub ntsej muag kawg kuj yog cov cim qhia meej tias cov khoom txuas yuav tsum tau hloov ncaj qha.
