Kev sib sib zog nqus -dub kev sib piv los pab cov engineers network thiab pab pawg neeg yuav khoom xaiv qhov zoo multimode fiber ntau rau lawv cov infrastructure
Thaum lub tuam txhab logistics hauv New Jersey tau hu rau peb lub quarter dhau los txog kev txhim kho lawv lub tsev khaws khoom lag luam, lawv tau ntsib qhov teeb meem tshwm sim: lawv cov OM1 cabling uas twb muaj lawm tsis tuaj yeem txhawb nqa 10GbE keyboards lawv nyuam qhuav yuav. Tus kws tshaj lij ntawm -qhov chaw tau pom zoo OM4, tab sis puas yog qhov overkill rau kev khiav nruab nrab ntawm 85 meters? Qhov xwm txheej no tshwm sim txhua hnub nyob rau hauv cov chaw khaws ntaub ntawv, tsev kawm ntawv, thiab chaw lag luam thoob ntiaj teb.
Multimode fiber ntau xaiv tsis yog tsuas yog xaiv cov xim -coded cable- nws yog hais txog kev nkag siab lub physics ntawm lub teeb propagation, txuam koj infrastructure rau tam sim no thiab yav tom ntej bandwidth xav tau, thiab optimizing koj peev peev. Cov lus qhia no dhau mus dhau qhov chaw - qib kev qhia tshwj xeeb los piav qhiavim li cascov fibers no ua haujlwm txawv thiabua li caskom paub txiav txim siab rau koj qhov kev xa tawm tshwj xeeb.
Dab tsi ua Multimode Fiber "Multimode"
Ua ntej dhia mus rau hauv OM kev faib tawm, cia peb tsim qhov txawv ntawm qhov sib txawv ntawm cov fiber ntau los ntawm nws ib leeg -mode counterpart ntawm theem pib.
Multimode fiber ntau nta ib txoj kab uas hla loj dua -feem ntau 50μm lossis 62.5μm piv rau ib leeg -mode's 9μm core. Cov tub ntxhais loj dua no tso cai rau lub teeb mus los ntawm cov fiber ntau nrog ntau txoj hauv kev ib txhij, txhua txoj hauv kev sawv cev rau qhov sib txawv "hom" ntawm kev nthuav tawm. Xav txog nws zoo li txoj kev loj uas muaj ntau txoj kab sib piv rau ib txoj kab - txoj kev: ntau txoj kab txhais tau tias muaj peev xwm khiav tau ntau dua li luv luv, tab sis kev sib koom ua ke yuav nyuaj dhau qhov ntev dua.
Cov tub ntxhais -rau- cladding interface nyob rau hauv graded-index multimode fiber tsis yog ib tug ntse ciam teb tab sis ib tug gradual hloov nyob rau hauv refractive index. Qhov no gradient yog precisely engineered kom sib npaug lub sij hawm mus txawv tebchaws ntawm ntau hom. Lub teeb mus ncig ze ntawm lub ntug ntawm fiber ntau yuav siv sij hawm ntev dua lub cev tab sis txav mus los ntawm qis dua -refractive- cov khoom ntsuas (thiab yog li mus nrawm dua), thaum lub teeb nyob ze ntawm qhov chaw yuav siv sij hawm luv dua los ntawm kev siab dua -refractive- cov khoom ntsuas (tsav qeeb). Thaum zoo kawg nkaus tuned, txhua hom tuaj txog ntawm lub receiver ib txhij.
Hauv kev xyaum, kev tsim kev kam rau siab txhais tau tias qhov nyiaj them no yeej tsis zoo tag nrho. Qhov tshwm sim lub sij hawm sib txawv ntawm hom - hu ua modal dispersion - thaum kawg txwv cov fiber ntau bandwidth thiab kis tau tus mob. Qhov no yog qhov tseem ceeb parameter uas cais OM1 txog OM5.
Lub Evolution ntawm LED rau VCSEL: Nkag siab txog Bandwidth Revolution
OM kev faib tawm cov txheej txheem qhia txog kev hloov pauv hauv lub teeb pom kev siv thev naus laus zis uas tshwm sim thaum xyoo 1990s thiab thaum ntxov 2000s.

Fiber Optic Patch Cords:Ua ntej- tau txiav OM3, OM4, thiab OM5 cov rooj sib txoos hauv kev teeb tsa yooj yim, duplex, thiab MPO/MTP. Kev cai ntev ntawm 0.3m mus rau 100m + nrog ceev tig.
Fiber Optic Connectors:LC, SC, FC, ST, thiab MPO / MTP connectors nrog precision zirconia ceramic ferrules. Insertion poob<0.2dB, return loss >50dB ib. Muaj nyob rau hauv PC, UPC, thiab APC polish hom.
Fiber Optic Pigtails:Factory- polished pigtails rau fusion splicing daim ntaub ntawv. OS2 ib leeg-mode thiab OM1-OM5 multimode variants nrog LSZH lossis PVC tsho.
Fiber Optic Adapters:Vaj huam sib luag-mount thiab bulkhead adapters nrog tooj liab lossis ceramic alignment tes tsho. Simplex, duplex, thiab quad configurations.
PLC Splitters:1x2 txog 1x64 phua qhov sib piv hauv liab qab fiber ntau, ABS module, LGX cassette, thiab khib-mount pob rau FTTH/PON xa tawm.
Terminal Boxes thiab Distribution Frames:Phab ntsa-mount thiab khib-mount enclosures nrog kev sib txuas cov tais thiab thaj vaj huam sib luag rau kev tswj hwm cable.
Peb qhov chaw tsim khoom hauv Shenzhen tuav ISO 9001 daim ntawv pov thawj nrog kev tswj xyuas zoo nrog rau 100% kev ntsuas qhov muag ntawm txhua qhov kev sib dhos. Nrog 12+ xyoo dhau los ntawm kev lag luam kev lag luam thiab kev muaj peev xwm txhua xyoo ntau tshaj 50 lab cov khoom sib txuas, peb ua haujlwm rau cov neeg siv xov tooj, cov chaw tsim cov ntaub ntawv, thiab cov neeg siv khoom lag luam thoob plaws 50+ lub teb chaws.
Txawm hais tias koj xav tau cov khoom lag luam tus qauv nrog rau tom ntej - hnub xa khoom lossis kev cai - engineering cov kev daws teeb meem rau cov kev xav tau tshwj xeeb, peb pab neeg ua haujlwm tau npaj los txhawb koj qhov project los ntawm kev tsim los ntawm kev teeb tsa.
