Nrog cov ntaub ntawv nce tsheb tau nrawm dua, ntau cov kev pabcuam tshwm sim thiab cov ntawv thov txuas ntxiv, thiab qhov kev thov rau cov bandwidth siab thiab kev kub ceev hauv cov chaw zov me nyuam cov ntaub ntawv tau nce ceev. Nws tawm tsam rau cov keeb kwm yav dhau los no OM5 fiber tau pom zoo raws li kev hloov kho tshiab multimode fiber (MMF) rau kev kub ceev cov ntaub ntawv nruab nrab cov ntawv thov. Nyob rau tib lub sijhawm, OM5 txoj hlua hluav taws xob zoo txuas tau pib ua kom cov neeg nyiam mloog thoob plaws hauv kev lag luam. Yog li, dab tsi yog qhov dav txhawj OM5 fiber jumper? Dab tsi yog qhov sib txawv ntawm nws thiab yav dhau los OM3 / OM4 fiber ntau jumper?
OM5 fiber ntau yog dab tsi?
Optical fiber thaj kab txuas yog siv los ua cov kab hluav taws xob los ntawm cov cuab yeej rau cov kab hluav taws xob cov hlua txuas. Muaj cov tuab tuab tiv thaiv txheej txheem, uas feem ntau siv rau hauv kev sib txuas ntawm cov khoom siv kho qhov muag thiab lub thawv davhlau ya nyob twg. Nws yog siv hauv cov kab ke kev sib txuas lus fiber ntau, kho qhov muag hluav taws xob fiber ntau cov kab ke, cov ntaub ntawv kho qhov muag fiber ntau, thiab thaj chaw hauv cheeb tsam. Nrog cov kev txhim kho tas mus li ntawm cov ntaub ntawv nruab nrab cov kev xav tau rau kev xa cov nqi, OM5 fiber patch cords tau pib siv ntau dua thiab ntau dua.
Thaum pib, OM5 cov khoom siv dhia fiber ntau tau hu ua broadband multimode fiber ntau cov neeg dhia khoom (WBMMF), uas yog tus qauv tshiab rau cov khoom siv fiber ntau tau txhais los ntawm TIA thiab IEC, nrog rau lub cheeb fiber ntau ntawm 50 / 125μm. Piv nrog rau lwm cov dhia tawm ntawm OM3 thiab OM4 fiber ntau, OM5 cov khoom siv fiber ntau tuaj yeem siv rau kev thov ntau dua. Vim tias cov txheej txheem tsim tawm ntawm cov hluav taws xob optical fiber preforms rau OM5 fiber ntau lub tshuab hluav taws xob tau ua tiav zoo, nws tuaj yeem txhawb nqa cov kab hluav taws xob ntau dua.
Hais txog kev teeb tsa, nws tsis yog qhov txawv ntawm OM3 thiab OM4 fiber ntau lub tshuab dhia, yog li nws tau rov qab nrawm nrog cov tsoos OM3 thiab OM4 multimode fiber ntau lub cev. Nyob rau lub Ob Hlis 2017, TIA qhia meej meej tias cov cim xim ntawm OM5 fiber ntau lub tshuab dhia ua si yog aqua, cov tsho sab nrauv cov xim ntawm OM3 thiab OM4 fiber ntau cov neeg ua luam dej yog pas dej xiav thiab xiav, thiab OM3 thiab OM4 fiber ntau cov neeg dhia tseem tuaj yeem siv nrog OM5 fiber ntau qhov sib txawv. yog qhov uas lub nkoj taw siv ua ke. Cov xim ntawm cov hnab riam sab nraud yuav tsum tau hloov pauv kom yooj yim txheeb xyuas OM5 kev sib txuas.
Peb qhov kev ua tau zoo ntawm OM5 fiber patch qaum
Muaj peb lub hauv paus muaj txiaj ntsig ntawm OM5 fiber ntau cov khoom. Ua ntej ntawm tag nrho cov, nws thawj kom zoo dua yog nws heev scalability. OM5 fiber ntau cov hlua txuas tuaj yeem sib txuas luv luv yoj yoj faib faib cov sib txuam sib luag (SWDM) thiab cov khoom xa hluav taws xob sib kis, thiab tsuas yog xav tau 8-core broadband multimode fiber (WBMMF). Nws tuaj yeem txhawb 200 / 400G Ethernet ntawv thov, thiab yav tom ntej daim ntawv thov muaj peev xwm yog qhov loj heev.
Qhov txiaj ntsig thib ob yog kev siv OM5 cov khoom siv dhia ua hluav taws xob tuaj yeem txo qis kev tsim kho thiab ua haujlwm. OM5 fiber ntau jumper rub tawm ntawm lub yoj yoj sib faib faib sib tshooj (WDM) thev naus laus zis ntawm hom fiber ntau los txuas ntxiv kom zoo dua siv tau yoj lub yoj qhov sib txawv thaum sib xa xov. Nws tuaj yeem txhawb 4 wavelengths ntawm 1-core multimode fiber thiab txo cov xov tooj ntawm cov fiber ntau qhov yuav tsum tau rau Lub quarter dhau los, uas tau txo qis cov xov hluav taws xob nqi ntawm lub network, kuj yog ib qhov laj thawj rau nws qhov kev lees txais dav.
Qhov thib peb kom zoo dua nyob rau hauv: OM5 fiber jumper muaj qhov pom tseeb zoo hauv kev sib txuam thiab kev sib txuam, thiab tuaj yeem pab txhawb cov kev siv ib txwm ua OM3 fiber ntau jumper thiab OM4 fiber jumper. Ntxiv rau, nws tau tag nrho nrog OM3 thiab OM4 fiber ntau thaj ua kev cai cable, thiab kev sib cuam tshuam ntawm lawv yog qhov muaj zog heev.
Ntsib cov kev xav tau ntawm high-speed data center kis
OM5 fiber ntau thaj muab cov khoom siv muaj zog tseem ceeb rau ultra-loj cov ntaub ntawv chaw. Nws tawg tau los ntawm lub qia ntawm lub tshuab hluav taws xob sib kis thiab cov khoom sib kis qis siv los ntawm cov tsoos multimode fiber. Tsis tsuas yog nws tuaj yeem siv tsawg dua multimode fiber cores los txhawb cov kev sib txuas hauv lub network nrawm dua, tab sis kuj, vim tias nws siv qis tus nqi hluav taws xob qis luv luv, kev siv nyiaj thiab kev siv fais fab ntawm lub khoos phis tawj yuav muaj ntau dua li ib hom uas siv cov kev ua haujlwm ntev ntev laser. fiber ntau. Yog li no, nrog kev txhim kho tas li ntawm qhov yuav tsum tau xa cov khoom xa mus, OM5 cov khoom siv hluav taws xob fiber yuav muaj cov ntaub ntawv thov rau yav tom ntej 100G / 400G / 1T ultra-loj cov ntaub ntawv chaw.
Coj thawj tiam ntawm 400G Ethernet fiber ntau xov txuas ntxiv yav tom ntej ua piv txwv, tag nrho ntawm 16 txoj hlua hluav taws xob yuav tsum xa cov cim thiab 16 core fibers raug siv kom tau txais cov cim. Yuav tsum muaj 32 tus xov tooj tseem ceeb thiab cov xov tooj hluav taws xob ntau, uas txhais tau hais tias cov ntaub ntawv chaw yuav tsum siv 32 Cov Phiaj Hlau nrog cov tub ntxhais tseem ceeb MPO / MTP interface. Yog li no, tus nqi siab ntawm cabling yuav zam dhau txoj kev nyuaj siab loj rau cov neeg siv ntaub ntawv lub chaw nruab nrab.
Yog tias koj siv OM5 fiber dhia lub luag haujlwm thiab luv nthwv dej faib sib faib ntau yam sib txuam sib txuam, tsuas yog 8 tus tub ntxhais siv tau cov xov hluav taws xob, ntawm 4 lub xov tooj hluav taws xob tau siv los xa cov cim, thiab 4 tus xov tooj hluav taws xob tau siv kom tau txais cov paib, thiab txhua qhov fiber kis 4 txhua qhov ntev. , Qhov kis tau tus mob ntawm txhua lub wavelength yog 25Gbps, yog li ntawd, txhua qhov tseem ceeb ntawm OM5 fiber jumper tuaj yeem xa cov ntaub ntawv 100Gbps. Los ntawm kev siv cov thev naus laus zis ntawm kev sib faib luv luv ntawm lub tshav puam sib kis thiab cov kab sib kis loj, cov nqi cabling ntawm cov ntaub ntawv nruab nrab yuav raug txo kom tsawg, thiab ntseeg tau tias OM5 fiber patch qaum yuav siv dav nyob rau yav tom ntej.
