OM5
Raws li ISO / IEC 11801, OM5 fiber ntau qhia meej qhov ntau ntawm qhov ntev ntawm 850nm thiab 953nm. Nws tau tsim los pab txhawb nqa Wave Wavethth Division Multiplexing (SWDM), uas yog ib qho ntawm ntau cov txuj ci tshiab tsim rau kis ntawm 40Gb / s thiab 100Gb / s. Lub Rau Hli 2016, qhov tshiab broadband multimode fiber ntau tus qauv ANSI / TIA-492AAAE tau pom zoo rau kev tshaj tawm. Thaum Lub Kaum Hlis 2016, OM5 fiber tau tshaj tawm lub npe kev ua haujlwm ntawm cov xov hlau uas suav nrog WBMMF (Broadband Multimode Fiber) hauv ISO / IEC 11801. Txij thaum ntawd los, OM5 yuav dhau los ua qhov kev xaiv tshiab rau cov chaw zov me nyuam cov ntaub ntawv uas xav tau ntau qhov kev sib txuas. Muaj kev kub ceev dua.
OM4 thiab OM5: Qhov txawv ntawv yog dab tsi?
Txij li OM1 thiab OM2 optical fibers tsis tuaj yeem txhawb kev xa cov ntaub ntawv nrawm ntawm 25 Gbps thiab 40 Gbps, OM3 thiab OM4 yog cov kev xaiv tseem ceeb rau multimode optical fibers uas txhawb 25G, 40G, thiab 100G Ethernet. Txawm li cas los xij, raws li cov kab xev xav tau nce, tus nqi ntawm cov kab hluav taws xob fiber optic txhawb nqa cov cim ntxiv Ethernet ceev tsiv teb chaws kuj nce ntxiv. Hauv cov ntsiab lus no, OM5 fiber tau yug los nthuav qhov zoo ntawm multimode fiber hauv cov ntaub ntawv chaw.
Qhov tseem ceeb sib txawv ntawm lawv yog tias 4700 MHz-km, EMB ntawm OM4 fiber tsuas yog teev ntawm 850 nm, thaum OM5 EMB tus nqi tau teev tseg ntawm 850 nm thiab 953 nm. Tus nqi ntawm 850 nm yog ntau dua OM4. Yog li no, OM5 fiber muab cov neeg siv khoom ntev dua thiab muaj kev xaiv fiber ntau ntxiv. Ib qho ntxiv, TIA tau tsim cov txiv qaub ntsuab raws li lub laj fai cable tsho xim rau OM5, thaum OM4 yog lub tsho dej. OM4 yog tsim rau 10Gb / s, 40Gb / s thiab 100Gb / s kis, tab sis OM5 yog tsim rau 40Gb / s thiab 100Gb / s kis, uas tuaj yeem txo cov xov hluav taws xob rau cov kis loj.
Ib qho ntxiv, OM5 cable tuaj yeem txhawb plaub plaub SWDM channel, txhua channel coj 25G cov ntaub ntawv, siv ib khub ntawm multimode fiber los muab 100G Ethernet. Ntxiv rau, nws pib sib xyaw nrog OM3 thiab OM4 fibers. OM5 tuaj yeem siv rau kev teeb tsa hauv ntau qhov chaw lag luam thoob plaws ntiaj teb, los ntawm thaj chaw hauv tsev kawm ntawv mus rau hauv cov ntaub ntawv chaw. Hauv ntej, OM5 fiber ntau zoo dua OM4 hauv kev sib kis, kev ceev thiab nqi.
