Hauv kev teeb tsa fiber ntau kho qhov muag, kev ntsuas kom raug thiab suav cov kev sib txuas ntawm cov khoom siv fiber ntau yog ib kauj ruam tseem ceeb heev los xyuas qhov tseeb ntawm lub network thiab xyuas kom muaj kev ua haujlwm ntawm lub network. Cov fiber ntau optical yuav ua rau pom tseeb tsis pom tseeb (uas yog, optical fiber ntau poob) vim lub teeb nqus thiab tawg, uas yuav cuam tshuam rau kev ntseeg siab ntawm optical transmission network. Yog li yuav ua li cas peb thiaj paub qhov poob nqi ntawm qhov txuas fiber ntau? Tsab ntawv xov xwm no yuav qhia koj yuav ua li cas los laij cov kev poob hauv kev sib txuas ntawm fiber ntau thiab yuav txiav txim siab li cas ntawm kev sib txuas ntawm fiber ntau optic.
Hom kev poob fiber ntau: Fiber poob tseem hu ua lub teeb attenuation, uas yog hais txog lub teeb poob ntawm qhov kawg ntawm qhov kawg thiab qhov kawg tau txais fiber ntau. Muaj ntau ntau qhov laj thawj rau kev poob fiber ntau, xws li cov khoom siv kho qhov muag fiber ntau nqus / tawg ntawm lub teeb lub zog, khoov poob, txuas txuas, thiab lwm yam.
Raws li qhov tshwm sim, muaj ob lub laj thawj tseem ceeb rau kev poob fiber ntau: cov khoom siv sab hauv (uas yog, cov yam ntxwv ntawm cov khoom siv kho qhov muag) thiab lwm yam (uas yog, tshwm sim los ntawm kev ua haujlwm tsis zoo ntawm optical fiber), uas tuaj yeem muab faib ua cov khoom siv kho qhov muag. fiber ntau poob thiab non-intrinsic optical fiber poob. Kev poob ntawm cov fiber ntau yog ib hom kev poob ntawm cov khoom siv fiber ntau, uas feem ntau suav nrog kev nqus tsis zoo, tawg tawg thiab tawg tawg los ntawm kev ua haujlwm tsis zoo. Qhov uas tsis yog-intrinsic fiber ntau feem ntau suav nrog vuam poob, connector poob thiab dabtsi yog khoov poob.
Cov Qauv rau Fiber Poob: Lub Telecommunications Industry Alliance (TIA) thiab Electronic Industry Alliance (EIA) tau ua haujlwm ua ke los tsim EIA / TIA tus qauv, uas qhia txog kev ua tau zoo thiab kev xa mus rau cov khoom siv kho qhov muag thiab cov khoom sib txuas thiab tam sim no tau txais dav thiab siv hauv fiber optic kev lag luam. EIA / TIA cov qauv qhia tias qhov siab tshaj plaws attenuation yog ib qho tseem ceeb tshaj plaws hauv kev ntsuas fiber ntau. Qhov tseeb, qhov siab tshaj plaws attenuation yog qhov attenuation ntawm cable, hauv dB / km. Daim duab hauv qab no qhia tau hais tias qhov siab tshaj plaws attenuation ntawm ntau hom cable hauv EIA / TIA-568 tus qauv specification.
Optical cable hom Wavelength (nm) Max attenuation (dB/km) Yam tsawg kawg nkaus bandwidth (Mhz * Km) 50/125 multimode 8503.550013001.550062.5 mu m / 125 microns multimode optical fiber ntau 8503.501601 .0-13101.0 sab nraum zoov ib leeg -hom optical fiber ntau cable - 15500.5-13100.5
Saum toj no yog cov lus qhia dav dav ntawm Optical Fiber poob, Kuv vam tias yuav pab koj xav tau.
Ntxiv rau qhovONUseries, transceiver series,OLTseries, Shenzhen HDV Photoelectron Technology Ltd. kuj tsim module series, xws li: kev sib txuas lus kho qhov muag module, kho qhov muag kev sib txuas lus module, network optical module, kev sib txuas lus optical module, optical fiber module, Ethernet optical fiber module, thiab lwm yam., tuaj yeem muab cov kev pabcuam zoo sib xws rau sib txawv cov neeg siv xav tau, txais tos koj tuaj xyuas.
