Txij li thaum Kao tau hais tias cov fibers kho qhov muag tuaj yeem siv rau kev sib txuas lus, kev siv tshuab kho qhov muag tau vam meej nrog rau cov khoom siv kho qhov muag, hloov lub ntiaj teb. Optical fiber ntau tuaj yeem hais tau tias yog lub hauv paus ntawm kev sib txuas lus kho qhov muag, thiab yuav luag txhua qhov kev sib kis ntawm cov thev naus laus zis tam sim no xav tau cov khoom siv fiber ntau ua qhov nruab nrab kis.
Tam sim no, ntau ntau hom optical fibers tau tsim nyob rau hauv kev lag luam rau ntau yam kev siv scenarios, tab sis lawv txhua tus muaj qhov tsis zoo sib txawv, ua rau muaj kev tsis zoo thoob ntiaj teb.
Cov fibers kho qhov muag tam sim no siv rau WDM cov kab ke sib kis feem ntau yog ib hom fiber ntau xws li G.652, G.655, G.653 thiab G.654.
● G.652 fiber ntau yog txwv nyob rau hauv kev sib txuas lus kev taw qhia vim nws kis tau tus mob thiab cov yam ntxwv tsis-linear;
● G.655 fiber ntau muaj cov nyhuv nonlinear zoo vim qhov me me fiber ntau dispersion thiab me me ua haujlwm zoo ntawm qhov chaw hla, thiab qhov kev sib kis deb tsuas yog 60% ntawm G.652;
● G.653 fiber ntau muaj qhov cuam tshuam tsis zoo ntawm cov kab ntawm DWDM vim yog qhov sib xyaw ntawm plaub-yoj, thiab lub zog nkag ntawm cov fiber ntau yog tsawg, uas tsis tsim nyog rau kev sib kis ntawm ntau-channel WDM saum toj 2. 5g ;ua.
● G.654 fiber ntau yuav muaj kev cuam tshuam zoo rau kev sib kis ntawm cov kab ke vim muaj ntau qhov kev cuam tshuam ntawm cov khoom siv kho qhov muag ntawm cov kev txiav txim siab, thiab tib lub sijhawm nws yuav tsis tuaj yeem ua tau raws li cov kev xav tau ntawm kev xa mus rau yav tom ntej nthuav dav rau S bands, E thiab O. .
Qhov tsis muaj kev ua tau zoo ntawm cov pa fiber ntau hauv kev ua lag luam niaj hnub no tseem yuam kev lag luam kom nce qib tom ntej fiber ntau optic technology kom sai li sai tau. LEE, lub hom phiaj kev lag luam tseem ceeb ntawm cov khoom siv kho qhov muag ntawm Shenzhen Aixton Cable Co., Ltd., siv lub zeem muag ntawm lwm tiam neeg siv fiber ntau optics ua ib qho ntawm cuaj qhov teeb meem loj uas ntsib cov kev sib txuas lus kho qhov muag tseem ceeb hauv kaum xyoo tom ntej. Nws ntseeg hais tias kom ua tau raws li qhov yuav tsum tau muaj ntawm qhov kev ncua deb thiab duplication peev xwm, thiab ua raws li Moore txoj cai ntawm lub teeb nyob rau hauv txoj kev loj hlob ntawm wavelength division kev lag luam, tiam tom ntej ntawm optical fibers yuav tsum muaj cov nram qab no nta: Ua ntej, kev ua haujlwm siab, qis. intrinsic poob thiab tsis kam mus rau non-linear teebmeem Loj muaj peev xwm; qhov thib ob yog lub peev xwm loj, uas npog tag nrho lossis ntau dua muaj spectrum; qhov thib peb yog tus nqi qis, tuaj yeem tsim tau, suav nrog: yooj yim rau kev tsim khoom, tus nqi yuav tsum sib piv los yog ze rau G.652 fiber ntau, yooj yim rau kev xa tawm thiab tswj tau yooj yim.
