Kev loj hlob sai ntawm fiber ntau rau tsev, uas yog FTTR, tag nrho-optical wi-fi kev daws kom ncav cuag txhua chav kom ua tiav kev pab them nqi gigusage txhua qhov chaw hauv tsev lossis lub tsev. Tab sis nyob rau hauv qee qhov xwm txheej tshwj xeeb, FTTR yog qhov nyuaj dua kom ua tiav, yog li peb xav tau qee lub zog sab nraud los pab ua tiav FTTR kev tsim kho FTTR. Qhov pom tau cov ntsiab lus ntawm FTTr kev txuas ntxiv yog qhov txuas tau zoo ntawm FTTr tib yam uas muab txoj kev sib zog tsis pom zoo thiab nrawm dua qub hauv chav. Nws tuaj yeem pab ua kom nrawm dua qhov kev saws cov kev pabcuam fiber ntau los ntawm kev txhim kho sai dua li cov txiaj ntsig pom zoo ib txwm muaj. Cov kev pab no tuaj yeem ua rau cov neeg lees txais siab dua thiab cov nqi yuav txais. Siv 3M meej nplaum nplaum, engineers lossis subscribers tau yooj yim txuas rau ntawm phab ntsa.
Kev qhia teeb tsa: Tsuas tshem cov nplaum tiv thaiv cov yeeb yaj kiab thiab kev ua tiav nrog txoj kev tsim kho me me uas "tau txais nws txoj cai txhim kho kev ua tau zoo. Ib txhij, nws dag zog tensile kev ua tau zoo thiab ua kom zoo dua cov lus nplaum ntev ntev, kos rau ib qho kev yooj yim ntawm kev siv thiab kev ntseeg tau.
