Kev nthuav dav sai ntawm fiber ntau optic tes hauj lwm, suav nrog cov ntaub ntawv cov kev pabcuam ntsuas hauv cov ntaub ntawv ntim lossis bandwidth, qhia tias fiber ntau optic kis tau tus mob thev naus laus zis yog thiab yuav txuas ntxiv yog ib feem tseem ceeb ntawm lub network yav tom ntej.Cov neeg tsim khoom siv network tau yooj yim dua nrog cov kev daws teeb meem fiber ntau, raws li kev siv fiber ntau optic cov kev daws teeb meem ua rau muaj kev hloov pauv tau yooj yim dua network architectures thiab lwm yam txiaj ntsig xws li EMI (electromagnetic cuam tshuam) resiliency thiab cov ntaub ntawv kev ruaj ntseg.Fiber optic transceivers ua lub luag haujlwm tseem ceeb hauv cov kev sib txuas ntawm fiber ntau optic.Thaum tsim cov fiber ntau optic transceiver, muaj peb yam uas yuav tsum tau xav txog: ib puag ncig tej yam kev mob, hluav taws xob tej yam kev mob, thiab kho qhov muag kev ua tau zoo.
Dab tsi yog fiber optic transceiver?
Fiber optic transceiver yog ib qho kev ywj pheej uas xa thiab tau txais cov teeb liab.Feem ntau, nws ntsaws rau hauv ib lub cuab yeej uas muab ib lossis ntau dua transceiver modules, xws li router lossis network interface card.Lub transmitter siv hluav taws xob tawm tswv yim thiab hloov nws mus rau lub teeb tawm ntawm lub laser diode lossis LED.Lub teeb los ntawm lub transmitter yog txuas rau hauv fiber ntau los ntawm kev sib txuas thiab xa mus los ntawm cov khoom siv fiber ntau optic.Lub teeb los ntawm qhov kawg ntawm fiber ntau yog txuas mus rau lub receiver, qhov twg lub detector converts lub teeb mus rau hauv ib tug hluav taws xob teeb liab, uas yog tsim nyog conditioned rau siv los ntawm lub receiver.
Kev txiav txim siab tsim
Fiber optic links yeej muaj peev xwm tswj tau cov ntaub ntawv ntau dua nyob ntev dua piv rau cov kev daws teeb meem tooj liab, uas tau ua rau kev siv dav ntawm fiber ntau optic transceivers.Thaum tsim fiber ntau optic transceivers, cov nram qab no yuav tsum tau xav txog.
Environmental mob
Ib qho kev sib tw yog los ntawm huab cua sab nraud-tshwj xeeb yog huab cua hnyav ntawm qhov siab lossis raug pom.Cov khoom siv no yuav tsum ua haujlwm nyob rau hauv ib puag ncig huab cua thiab dhau qhov kub ntawm qhov dav.Ib qho kev txhawj xeeb thib ob cuam tshuam txog kev tsim fiber ntau optic transceiver yog motherboard ib puag ncig uas suav nrog kev siv hluav taws xob thiab cov yam ntxwv thermal.
Ib qho txiaj ntsig tseem ceeb ntawm fiber ntau optic transceivers yog lawv cov kev xav tau hluav taws xob tsawg.Txawm li cas los xij, qhov kev siv hluav taws xob tsawg no tsis yog txhais tau tias thermal tsim tuaj yeem tsis quav ntsej thaum sib sau ua ke tus tswv tsev teeb tsa.Kev ua pa txaus los yog airflow yuav tsum tau suav nrog los pab cuam tshuam cov thermal zog tawm ntawm lub module.Ib feem ntawm qhov yuav tsum tau ua yog ua tau raws li tus qauv SFP tawb mounted rau ntawm lub motherboard, uas kuj ua raws li lub thermal zog conduit.Cov ntaub ntawv ntsuas kub tau tshaj tawm los ntawm Digital Monitor Interface (DMI) thaum lub mainframe ua haujlwm ntawm nws qhov siab tshaj plaws tsim kub yog qhov kev sim siab kawg ntawm kev ua tau zoo ntawm tag nrho cov txheej txheem thermal tsim.
Hluav taws xob tej yam kev mob
Qhov tseem ceeb, fiber ntau optic transceiver yog ib qho khoom siv hluav taws xob.Yuav kom tswj tau qhov kev ua yuam kev tsis muaj kev ua haujlwm ntawm cov ntaub ntawv dhau los ntawm lub module, lub hwj huam mov rau lub module yuav tsum ruaj khov thiab tsis muaj suab nrov.Qhov tseem ceeb tshaj, lub hwj huam mov tsav lub transceiver yuav tsum tau lim kom zoo.Cov ntxaij lim dej raug teev tseg hauv Daim Ntawv Pom Zoo Ntau Yam (MSA), uas tau coj tus qauv tsim ntawm cov transceivers no.Ib qho qauv tsim hauv SFF-8431 specification yog qhia hauv qab no.
Optical zog
Optical kev ua tau zoo yog ntsuas hauv qhov yuam kev me ntsis lossis BER.Qhov teeb meem ntawm kev tsim kho qhov muag transceiver yog qhov tsis pom kev ntawm lub tshuab xa hluav taws xob thiab lub receiver yuav tsum tau tswj kom muaj peev xwm attenuation ntawm lub teeb liab optical thaum nws mus rau hauv cov fiber ntau tsis ua rau BER ua haujlwm tsis zoo.Lub ntsiab tsis txaus siab yog BER ntawm qhov txuas tiav.Ntawd yog, qhov pib ntawm qhov txuas yog lub hauv paus ntawm lub teeb liab hluav taws xob uas tsav lub transmitter, thiab thaum kawg, lub teeb liab hluav taws xob tau txais los ntawm tus txais thiab txhais los ntawm lub circuitry hauv tus tswv tsev.Rau cov kev sib txuas lus sib txuas uas siv optical transceivers, lub hom phiaj tseem ceeb yog los lav BER kev ua tau zoo ntawm qhov sib txawv ntawm qhov sib txawv thiab kom ntseeg tau tias muaj kev sib cuam tshuam nrog cov neeg thib peb transceivers los ntawm cov neeg muag khoom sib txawv.
