Traditional fiber video converters yog siv rau point-to-point daim ntaub ntawv. Lub fiber ntau video converter yog ntsia ntawm ob qho kawg ntawm qhov kho qhov muag fiber ntau, xws li feem ntau siv optical fiber ntau Ethernet transceiver, uas siv optical fiber txuas rau lub computer network ntawm ob qho kawg. Thiab nyob rau qee lub sijhawm xws li hluav taws xob, kev txuag dej, thiab lwm yam. Obviously, hom kev sib txuas tau txwv ntau heev. Lub sijhawm no, cov khoom siv kho qhov muag thiab cov khoom siv yuav tsum tsim kom muaj lub nplhaib sib txuas. Cov khoom siv kho qhov muag xav tau lub nplhaib network kho qhov muag dav dav: nruab nrab yog qhov sib txuam, cov teeb liab sib txuas lus (xov tooj / video / Ethernet / serial chaw nres nkoj, thiab lwm yam), nws txuag kev nqis peev ntawm cov khoom siv kho qhov muag rau qhov loj thiab txhim kho kev siv tus nqi ntawm cov tub ntxhais fiber ntau. , uas yog tsim nyog thiab tsim nyog nyob rau hauv kev siv tswv yim.

Lub nplhaib hom Fiber Video Converter yog dab tsi?

Ring Type Fiber Video Converter xav tau cov cuab yeej nrog tsawg kawg ob lossis ntau qhov chaw nres nkoj kho qhov muag, thiab cov chaw nres nkoj no yuav tsum muaj peev xwm paub txog kev tiv thaiv tus kheej. Thaum ib qho ntawm qhov txuas tsis ua haujlwm, nws tuaj yeem xaiv lwm txoj hauv kev los sib txuas lus nrog lub chaw kom ntseeg tau tias kev sib txuas lus ib txwm tsis muaj qhov tsis raug.

Piv nrog cov cuab yeej siv tshuaj analog, cov thev naus laus zis thev naus laus zis muaj txiaj ntsig zoo hauv ntau yam. Ib yam li cov thev naus laus zis hloov pauv cov thev naus laus zis analog hauv ntau thaj chaw, digitization ntawm lub nplhaib network optical transceivers kuj yog ib qho kev zam tsis tau. Muaj ob txoj hauv kev tseem ceeb rau digital video nplhaib network optical transceiver: ib qho yog MPEGII duab compression digital nplhaib network fiber ntau video converter, thiab lwm yam yog tag nrho-digital uncompressed nplhaib network fiber ntau video converter.

Piv nrog rau cov tsoos analog nplhaib network fiber ntau video converter, lub nplhaib digital network video converter muaj qhov pom tseeb zoo:

1) Kev sib kis ntev: mus txog 80Km lossis ntev dua (120Km);
2) Kev them nyiaj yug video lossless relay relay, yog li siv ntau theem kev sib kis tau;
3) Tsawg ib puag ncig cuam tshuam thiab kev sib kis tau zoo;
4) Cov teeb liab txhawb nqa tuaj yeem ncav cuag 16 raws lossis ntau dua (32 raws, 64 raws, 128 raws).
