Txij li thaum Kao tau hais tias cov fibers optical tuaj yeem siv rau kev sib txuas lus, kev siv tshuab sib txuas lus optical tau vam meej nrog rau cov fibers optical, hloov pauv lub ntiaj teb. Optical fiber tuaj yeem suav hais tias yog lub hauv paus ntawm kev siv tshuab sib txuas lus optical, thiab yuav luag txhua yam kev siv tshuab sib kis optical tam sim no xav tau optical fiber ua qhov nruab nrab sib kis.
Tam sim no, ntau hom fiber ntau tau tsim nyob rau hauv kev lag luam rau ntau yam kev siv, tab sis lawv txhua tus muaj qhov tsis zoo sib txawv, ua rau tsis muaj kev thoob ntiaj teb.
Cov fibers optical uas siv rau WDM system kis tau feem ntau yog cov fibers ib hom xws li G.652, G.655, G.653 thiab G.654.
● G.652 fiber raug txwv nyob rau hauv kev coj ntawm kev sib kis vim nws qhov kev poob kis thiab cov yam ntxwv tsis sib xws;
● G.655 fiber muaj qhov cuam tshuam tsis zoo vim yog qhov me me ntawm cov fiber dispersion thiab thaj chaw me me ntawm qhov chaw hla, thiab qhov deb ntawm kev sib kis tsuas yog 60% ntawm G.652;
● G.653 fiber muaj kev cuam tshuam tsis zoo ntawm DWDM system channels vim yog plaub-yoj sib xyaw, thiab lub zog nkag fiber tsawg, uas tsis nyiam ntau-channel WDM kis tau siab dua 2.5G;
● G.654 fiber yuav muaj kev cuam tshuam loj rau kev sib kis ntawm lub cev vim muaj kev cuam tshuam ntau yam los ntawm cov qauv siab thiab, tib lub sijhawm, yuav tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev nthuav dav kis mus rau S, E, thiab O bands yav tom ntej.
Qhov kev ua haujlwm tsis zoo ntawm cov fiber ntau optical hauv kev ua lag luam tam sim no kuj yuam kom kev lag luam ua kom muaj kev nce qib hauv cov thev naus laus zis fiber ntau optical tiam tom ntej sai li sai tau. LEE, tus thawj coj kev npaj rau cov khoom siv optical ntawm Shenzhen Aixton Cable Co., Ltd., xav txog lub zeem muag ntawm cov fiber ntau optical tiam tom ntej ua ib qho ntawm cuaj qhov teeb meem loj uas ntsib cov thev naus laus zis sib txuas lus tseem ceeb hauv kaum xyoo tom ntej. Nws ntseeg tias kom ua tau raws li qhov yuav tsum tau ua ntawm qhov deb tas li thiab muaj peev xwm ob npaug, thiab ua raws li Moore Txoj Cai ntawm Lub Teeb hauv kev txhim kho kev lag luam faib wavelength, cov tiam tom ntej ntawm cov fiber ntau optical yuav tsum muaj cov yam ntxwv hauv qab no: Ua ntej, kev ua tau zoo siab, kev poob qis, thiab kev tiv thaiv rau cov teebmeem nonlinear; thib ob, muaj peev xwm siab, npog tag nrho lossis dav dua spectrum muaj; thiab thib peb, tus nqi qis thiab kev tsim qauv, suav nrog kev yooj yim ntawm kev tsim khoom, nrog tus nqi sib piv rau lossis ze rau ntawm G.652 fiber, yooj yim ntawm kev xa tawm, thiab yooj yim ntawm kev saib xyuas.
