Raws li txhua leej txhua tus paub, lub passive nyob rau hauv lub txiaj ntsim kho qhov muag network (PON) txhais tau hais tias ODN tsis muaj lwm yam khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Nws yog tsim los ntawm cov khoom tsis ua haujlwm xws li kho qhov muag. Yog li ntawd, qhov muag kho qhov muag pom tau. Nyob rau hauv qhov tseem ceeb ntawm cov kev ua haujlwm kho qhov muag tsis zoo, koj puas to taub qhov kev siv optical splitters thiab kho qhov muag seem hauv PON yog dab tsi?
PLC splitter yog dab tsi?
Optical splitters, los yog fiber ntau splitters lossis passive kho qhov muag splitters, yog cov tub ntxhais qhov muag khoom uas faib cov teeb pom kev zoo ntawm cov teeb pom kev zoo rau ntau lub tswv yim fibers, feem ntau siv rau hauv cov kev kho qhov muag pom zoo, feem ntau yog ib qho fiber ntau. Qhov kev tshaj tawm cov lus tshaj tawm hauv kev faib tawm yog muab faib rau ntau tus neeg siv cov khoom dav dav raws li ib qho piv txwv, yog li ntawd cov neeg siv dav dav dav dav cov neeg siv PON interface.
Optical splitter tov hauv kev tsim PON kev tsim kho
Nyob rau hauv PON qauv, qhov tsim ntawm optical splitter yuav tsum xav txog cov khoom xws li tus qauv ntawm lub xovtooj, qhov ceev ntawm cov neeg siv, thiab kev faib cov kev cai, kom mus cuag lub hom phiaj ntawm kev tsim kho. Hauv qab no qhia txog ntau daim ntawv thov.
1. Lub tsev tawg ntsa tawg
Thaum txoj kev nyob nruab nrab ntawm cov tuam tsev yog luv luv thiab cov neeg siv cov neeg siv yog loj thiab muaj zog, thaum nkag mus rau hauv chav tsev network yog ntev ntev hauv thaj chaw nyob thiab tsis muaj chaw hauv thaj chaw nyob, nws raug pom zoo kom tau txais ib qho kev faib tawm ncaj ncees . Qhov zoo ntawm qhov no yog tias qhov kis tau tus mob yog ntev. Muaj peev xwm ua tiav cov teeb meem zoo dua qub. Raws li pom hauv daim duab hauv qab no, qhov optical splitter muab tso rau hauv lub thawv rau cable cais thiab lub teeb ntawm lub cev muaj fiber ntau thiab cov khoom faib tawm.
2. Ua kom pom tseeb
Thaum lub tsev ntawm cov tsev sib kis tau yooj yim thiab tsis sib xws, xws li kev sib faib ntawm villas, kev ncua ntev, thiab cov neeg siv qis qis, kev siv cov teeb pom kev zoo tuaj yeem ua kom siv tas nrho cov kev pab thiab npog cov cheeb tsam ib puag ncig. Raws li pom hauv daim duab hauv qab no, qhov optical splitter yog muab tso rau hauv lub thawv rau cable, thiab lub teeb nruab nrig yog tau nruab nrab ntawm qhov muab faib tshuab thiab lub raj xa dej.
Hauv kev xaus, nws tuaj yeem pom tias cov teeb meem ntawm txoj kab sib txuas ntawm nruab nrab thiab lub suab qeg tsis ncaj cais tau muaj ntau daim ntawv thov scenarios. Lub centralized split lub teeb splitter tau yoog npog ntau ntau cov neeg siv qhov kawg, thiab cov faib splitter yog tsim rau ib lub tsev lossis ib cheeb tsam. Spectral, tab sis nws yuav tsum tau muab sau tseg tias hom no ua rau ntau lub PON ports, qhov kev thov rau optical splitters kuj yog ntau dua, yuav tsum ua tib zoo xav nrog ua ke nrog qhov teeb meem
