Nyob rau hauv hnub no lub ntiaj teb no, ib tug optical fiber yog siv los tswj ntau thiab ntau tes hauj lwm. Nws yog ib tug xov ntawm ib tug pob tshab khoom xws li iav los yog yas uas muaj peev xwm sawv ntawm Identify teeb hauv nws tus kheej vim rau tag nrho cov sab hauv thiaj. Tej fiber muaj ib tug tub ntxhais thiab ib tug cover nrog txawv refractive indices. Cov tub ntxhais, uas yog lub ntsiab distributor ntawm lub teeb lub teeb liab yog tsim los ntawm ib tug optically tuab khoom. Niaj hnub no, kho qhov muag fiber mus yuav tsis yog yooj yim. Nyob rau hauv tus txheej txheem ntawm lub tshaaj yog tsim nyog them sai sai mus rau cov xov tooj qhia los ntawm feem. Cov ntsuas qhia lub cheeb ntawm cov tub ntxhais thiab plhaub.
Nyob ntawm seb lub hom cais ib hom thiab multimode kho qhov muag fiber. Cov kev xaiv thawj muab rau cov kis ntawm lub teeb mem tes yog tsuas yog ib hom, rau qhov no yog vim li cas yog tsis muaj distortion ntawm cov dispersion. Rau hnub tim, yuav luag tag nrho cov ua fibers mus rau qhov no hom. Lawv feem ntau siv nyob rau hauv ntau yam ntawm lub ntsiab kab, qhov chaw uas siab zoo ntawm cov ntaub ntawv kis. Ntawm no, cov kis tau tus mob npaum li cas tsis adversely cuam tshuam, nyob rau hauv sib piv rau lub nruab nrog ib tug hluav taws xob lub teeb liab. Nrog lub advent ntawm kho qhov muag amplifiers dramatically nce lub peev xwm ntawm xws kab.
Incidentally, tus kho qhov muag fiber tau pom nws daim ntawv thov tsis tau tsuas yog nyob rau hauv lub teb ntawm network technologies. Nws kuj ua raws li ib tug sensor ntsuas kub, voltage, siab thiab lwm yam tsis. Lub me me luaj li cas thiab tsis xav tau kev pab rau hluav taws xob pub rau neeg nyob siab txaus nyob rau hauv tej cheeb tsam. Tsis tas li ntawd, tam sim no invention yog heev heev siv nyob rau hauv sonar thiab seismic pab kiag li lawm. Nws muaj lwm yam chaw ntawm qhov kev siv, uas yog ib tug teeb pom kev zoo muaj nuj nqi.
Feem ntau, fusion splicing ntawm fiber optic khoom enables spliced ua ke. heev tau mus cuag ob peb cables siv vuam machine. Thaum lub sij hawm ua hauj lwm yuav tsum tau ua raws li tej yam cov kev cai. Thawj lub fiber xaus yog tiav, thiab ces txo rau txhua lwm yam. melting txoj kev yog nqa tawm lub merger. Tsis Siv Neeg vuam tshuab tsis yuav tsum tau cov ntaub ntawv thiab kawm tuab si lug ntawm lub fibers, ces siv lawv zoo nyob heev. Txawm li cas los, qhov no tsis yog lub semi-analogues uas muaj tib neeg kev koom tes nyob rau hauv tej yam kev ua hauj lwm. Lawv tsis txhob siv kev cabling systems.
Rau tag nrho nws cov intricacies ntawm tus txheej txheem kho qhov muag fiber tsis muab ib tug heev stringent bans nyob rau hauv welding. Yog li, installers ua hauj lwm rau cov hom kev kawm uas yog lawv tus kheej pom tau hais tias pom. Heev nrov vuam txheej txheem splice muaj, ntawm chav kawm, thiab ib co tsis zoo. Lub ntsiab yog ib tug lub siab hnyav thiab loj qhov ntev ntawm lub caij, uas tiv thaiv lub weld tsam. Rau tus so, tsis muaj teeb meem muaj.
