Cov ntaub ntawv chaw yuav tsum tau nce mus rau 100G / 200G / 400G yav tom ntej. Cov chaw siv cov ntaub ntawv yuav tsum ntsib ntau hom kho qhov muag xws li IEEE, MSA, lossis cov khoom lag luam ntiag tug. Peb tsis tuaj yeem pom tias txoj kev xa sib kis lossis sib kis yuav siv tau rau yav tom ntej Raws li qhov kev sib txuas network tseem ceeb hauv cov ntaub ntawv chaw, cabling yuav tsum muaj kev qhib, muaj peev xwm thiab yoog tau los txhawb cov kev siv network sib txawv yav tom ntej.
OM5 multimode fiber ntau sib xws nrog ob qho tib si kev sib txuas lus xa hluav taws xob thiab cov qauv kho qhov muag uas txhawb du du kis tau tus mob, thiab OM5 fiber ntau tuaj yeem txo cov xov paj fiber ntau thiab nce qhov kev sib kis tau deb. Yog li, los ntawm qhov kev pom ntawm kev nqis peev tag nrho, kev nqis peev rov qab thiab kev pheej hmoo tiv thaiv hauv cov ntaub ntawv chaw Nws tuaj yeem pom tias OM5 fiber yog qhov sib kis tau nruab nrab rau kev sib txuas lus kho qhov muag hauv cov chaw zov me nyuam cov ntaub ntawv tshiab.
Kev faib ntau yam fiber ntau
Txij li thaum lub npe nrov ntawm Ethernet nyob rau xyoo 1990, ntau hom fiber ntau tau siv dav hauv cov ntawv thov luv luv xws li cov tsev lag luam thiab cov chaw khaws ntaub ntawv. Ntau hom fiber ntau tau tsim los ntawm thawj tiam OM1 rau tam sim no tiam thib tsib ntawm OM5. Cov tsoos OM1 rau OM4 multimode fiber ntau thev naus laus zis kev hloov kho yog feem ntau raws li kev tsim kho ntev ntev (nrog rau LED tshaj dhau emission bandwidth OFL thiab LD zoo hom bandwidth EMB), nrog qee qhov cuam tshuam Ethernet technologies xws li duplex + dual wavelength BiDi thiab kev tshwm sim ntawm SWDM4 technology rau luv luv wavelength faib multiplexing ceev xav tau hom tshiab ntawm multimode kho qhov muag fiber ntau uas tuaj yeem txhawb nqa qhov dav dua ntawm qhov ntev ntawm 850-950nm, thiab OM5 optical fiber tau los rau hauv. Txhawm rau txhawb los nthuav tawm SWDM4 luv luv wavelength faib multiplexing thiab BiDi duplex dual wavelength kev siv, TIA thiab ISO / IEC tso tawm cov txheej txheem kev ntawm TIA-492 AAAE thiab IEC60793-2-10 A1a.4b OM5 broadband multimode fiber hauv 2017, feem.
OM5 fiber muaj qhov sib kis tau zoo dua
OM5 nthuav dav nthwv dej txhawb los ntawm OM3 thiab OM4 fibers nyob rau hauv kev coj tom qab. Yog tias peb suav multimode fiber li txoj hauv kev loj, cov tsoos OM1, OM2, OM3, OM4 multimode fiber muaj tsuas yog ib qho channel, thaum OM5 muaj plaub kis, thiab lub peev xwm kis tau nce los ntawm plaub zaug.
OM5 fiber ntau txhawb qhov tseeb BiDi thiab SWDM thev naus laus zis
Los ntawm cov keeb kwm kev pom, cov tshuaj OM1 multimode fiber ntau yog tsim los rau 100M Ethernet, OM2 multimode fiber yog tsim rau 1G Ethernet, OM3 multimode fiber yog tsim tshwj xeeb rau 10G Ethernet, thiab OM4 multimode fiber yog tsim tshwj xeeb rau kev xa mus kis. 100GBase-SR4 Ethernet tsim, OM4 multimode fiber ntau ua kom zoo dua cov hom kev hloov pauv qeeb (DMD) ntawm OM3 multimode fiber ntau thaum muaj kev sib kis loj, yog li cov kis nrug tau zoo heev.
OM5 multimode fiber ntau txhawb nqa ntau dua wavelength channel, yog li nws tau txais txiaj ntsig ntau dua rau kev siv plaub-wavelength SWDM4 lossis dual-wavelength BiDi thev naus laus zis. OM5 fiber ntau tau tag nrho nrog cov qauv 40GBase-SR4 thiab 100G Base-SR4 optical modules. Nws tuaj yeem txhawb cov ntawv thov sib txawv hauv cov ntaub ntawv nruab nrab yav tom ntej.
OM5 fiber
Siv cov roj carbon fiber ntau los pab txhawb cov ntawv thov kom nrawm dua
Raws li lub chaw xaib ntaub ntawv network nce ceev, tus naj npawb ntawm fiber cores tseem yuav tsum tau nce. Tsoos OM3 thiab OM4 optical fibers feem ntau ua haujlwm ntawm 850nm wavelength. OM5 optical fiber muaj peev xwm txhawb 4 nthwv kab nruab nrab ntawm 850-950nm, yog li OM5 optical fiber kis tau 40/100 / 200G Ethernet tsuas yog yuav tsum tau siv ob txoj hlua hluav taws xob, thiab OM5 optical fiber txhawb tau 400G yav tom ntej. Ethernet, rau kev siv ntau dua ntawm 400G Ethernet kev siv, xws li 400G Base-SR 4.2 (4 khub ntawm fiber ntau 2 wavelengths, txhua channel siv 50G PAM4) lossis 400G Puag-SR4.4 ((4 khub ntawm fiber ntau 4 wavelengths, txhua channel siv 25GNRZ), xav tau tsuas yog 8-core OM5 fiber. Piv nrog thawj tiam 400G Ethernet 400G Base-SR16 (16 khub ntawm cov fibers, txhua channel kis 25Gbps), tus naj npawb ntawm optical fiber yuav tsum yog tsuas yog plaub zaug ntawm cov tsoos Ethernet ib Cov.
OM5 fiber ntau txhawb kev sib kis tau ntev
Rau 40G SWDM4 optical module, OM3 fiber kis kis las yog 240 meters, OM4 fiber kis tau nrug yog 350 meters, OM5 fiber kis tau nrug yog 440 meters; rau 100G SWDM4 optical module, OM3 fiber kis kis nrug yog 75 metres, OM4 fiber Kev sib kis yog 100 meters, thiab OM5 fiber kis tau nrug yog 150 meters. Rau 100G eSWDM4 optical module tso tawm los ntawm Finisar, qhov kis tau mus deb ntawm OM5 fiber yog 400 meters. Txog 40GBiDi module, OM3 fiber kis kis nrug yog 100 metres, OM4 fiber ntau kis nrug yog 150 metres, OM5 fiber kis kis nrug yog 200 meters; rau 100GBiDi module, OM3 fiber kis kis nrug yog 70 metres, OM4 fiber ntau kis nrug yog 100 meters, OM5 fiber kis kis nrug yog 150 meters.
Vim tias qhov khoos phis tawm kho qhov muag thiab cov kab hluav taws xob tau muaj cov npoo tsim nyog, qhov kev sib kis tau ntev yog ntau dua qhov kev sib kis tau muab los ntawm IEEE tus qauv thoob ntiaj teb lossis MSA ntau tus neeg muag khoom pom zoo. CommScope, Finisar thiab ExFO qhia txog 100G SWDM4 optical module ntawm Finisar ntawm 417-meter CommScope OM5 fiber txuas nrog xoom yuam kev sib kis ntawm lub rooj sib tham hauv kev lag luam nyiaj txiag xyoo no. Kev sim simulates qhov xav tau tshaj plaws rau 6 qhov kev sib txuas ntawm network txuas. Qhov 417-meter fiber txuas muaj rau MPO / LC fiber ntau lub thawv. ExFo cov cuab yeej ntsuas cov ntsuas ntsuas muaj qhov ntsuas tseem ceeb xws li tus nqi yuam kev me, dhia, thiab qeeb. Qhov ntsuas pom qhia tag nrho Cov ntsuas tsis pub dhau hauv kev ntsuas.
OM5 fiber ntau poob qis dua
ISO thiab TIA tso tawm cov qauv cabling tseeb ISO 11801 koob thib 3 thiab TIA / EIA.0-D xyoo 2017, feem. Tus txheej txheem tshiab tshem tawm ib txwm OM1, OM2 multimode optical cables thiab ntxiv OM5 broadband multimode optical cables. ISO txo qhov attenuation ntawm OM5 optical cable los ntawm 3.5 dB / Km ntawm yav dhau los OM3 thiab OM4 optical cable rau 3.0 dB / km, thiab ntxiv rau qhov xav tau bandwidth ntawm qhov ntev ntawm 953 nm. Cov pab pawg ua haujlwm thib peb ntawm ISO / IEC JTC1 SC25 WG3 tab tom tsim cov txheej txheem ntawm cov xov hluav taws xob rau kev sib kis ntawm cov kev siv high-speed network rau ntawm cov fiber ntau. Qhov tshwj xeeb no piv rau OM3, OM4, 10/40/100/200 / 400G duplex thiab cov kab ke sib txuas hauv network. Cov kev sib kis deb ntawm OM5 multimode fiber yog pom zoo rau cov chaw tsim ntaub ntawv tshiab.
OM5 Multimode Fiber Ecosystem
Raws li lub cev kis mus rau nruab nrab rau cov ntaub ntawv kev sib txuas lus, optical fiber muab kev txhawb nqa rau cov cuab yeej network. Kev nce qib ntawm OM5 fiber yog sib cais los ntawm kev txhawb nqa ntawm cov khoom siv network cov chaw tsim khoom. Nyob rau tam sim no, muaj ob lub thev naus laus zis rau kev xa cov kev kub ceev nrog cov xov tooj ntawm cov kho qhov muag me me hauv khw: BiDi thiab SWDM4. Cov cuab yeej siv tshuab cov khoom lag luam tam sim no muab BiDi suav nrog FIT, Cisco, H3C, BroadCade, thiab lwm yam.; SWDM4 cov ntaub ntawv muaj ntau tus neeg muag khoom zoo nrog Finisar, Lumentum, Dell EMC, H3C, Arista, Huawei, Hisense, thiab lwm yam Los ntawm qhov pom ntawm Ethernet ecological saw, OM5 multimode fiber thiab BiDi thiab SWDM4 cov khoom lag luam tsim tau ua tiav thiab dav cov kab ke tsiaj txhu. Nrog rau qhov nce ntawm cov zaub mov xa tuaj ntawm 40 / 100G network khoom siv thiab kev xa tawm ntau ntawm OM5 fiber, lub ecosystem tau maj mam dhau los.
OM5 multimode fiber ntau xeem
OM5 multimode fiber ntau soj ntsuam zoo tib yam li cov khoom siv hauv OM3, OM4 multimode fiber ntau khoom kuaj thiab cov txheej txheem ntsuas, cov neeg siv tsis tas yuav cov khoom siv kuaj ntxiv.
