Lub hauv paus tseem ceeb uas muaj kev cuam tshuam loj dua rau qhov sib txawv hauv ODN kev tsim kho kev siv peev txheej theem pib thiab theem nrab kev cais kho qhov muag muaj raws li hauv qab no:
(1) Tus naj npawb ntawm cov xoos ntawm cov khoom kho qhov muag cable hauv thawj-theem kev faib cov hom yog tus loj;
(2) Hauv thawj-theem kev faib cov hom, tus naj npawb ntawm cov hlua fiber ntau cable cores tom kawg ntawm qhov chaw faib khoom tau hloov thiab cov thawv fiber ntau tau ntxiv;
(3) Qhov thib ob optical splitting nyob ntau dua ntawm cov nqaj qaum fiber ntau thiab PON chaw nres nkoj.
Raws li kev laij tawm, thaum thawj qhov kho qhov muag ua kom pom qhov sib cais tau txais, kev nqis peev ntawm ODN yog siab dua qhov ntawm qhov kho qhov muag theem ob hauv cov xov hluav taws xob sib txawv. Yuav luag txhua qhov teeb meem tshwm sim, ODN peev ntawm theem kho qhov muag zaum ob txoj kev yog qhov tsawg dua qhov ntawm kev kho qhov muag ua ntej; qhov siab dua ntawm cov xov txuas piv, Cov tsev neeg muaj qhov ntau dua, qhov sib txawv ntawm kev nqis peev.
Hauv cov cheeb tsam uas tsis muaj ntom ntom ntawm cov tsev neeg, xws li cov chaw nyob deb nroog thiab villas, txawm hais tias muaj qhov sib txawv me me ntawm cov xov tooj ntawm cov kab hluav taws xob siv cov txheej txheem ntawm theem pib thiab theem qis kho qhov muag, qhov sib txawv hauv peev tseem muaj vim qhov sib txawv hauv cov naj npawb ntawm cores kawg ntawm qhov kho qhov muag cable, tab sis nws tsis zoo heev. Ntawd' s nws.
