Tsav los ntawm AI thiab daim ntawv thov cov ntaub ntawv loj xws li ChatGPT, lub ntiaj teb kev suav suav tau muaj kev loj hlob sai. Qhov kev loj hlob no ua rau muaj kev xav tau ntau dua ntawm cov ntaub ntawv chaw hauv tsev xws li GPUs, servers, thiab cov keyboards, tshwj xeeb tshaj yog hais txog cov ntaub ntawv xa mus thiab cov kev xav tau latency. Nyob rau hauv cov ntsiab lus ntawm kev sib txuas ntawm cov xov tooj sib txuas, txhua lub network congestion lossis pob ntawv poob hauv qhov txuas txuas tuaj yeem ua rau I / O qeeb. Yog li ntawd, yuav tsum muaj kev xav tau rau high-bandwidth, high-speed keyboards / optical modules, thiab kev sib txuas lus sib txuas uas tuaj yeem phim qhov kev thov no.

 

Raws li ib feem tseem ceeb ntawm kev lag luam saw, kev txhawb nqa muaj peev xwm ntawm multimode optical fiber ntau rau ib leeg-channel 100G kis tau tus mob nyob deb kuj yog ib qho tseem ceeb ntawm kev lag luam mloog. Peb tau pom tias Cisco, koom tes nrog tus khub Corning, tsis ntev los no tau luam tawm ib daim ntawv dawb sib koom ua ke ntawm Cisco lub vev xaib official. Daim ntawv no qhia txog hom tshiab ntawm high-speed multimode optical fiber optimized rau ib leeg-channel 100G VCSEL kis tau tus mob - HDR OM3 fiber ntau thiab HDR OM4 fiber ntau. Raws li daim ntawv dawb, ob hom tshiab ntawm multimode optical fiber ntau, piv rau cov qauv OM3 thiab OM4 fibers, optimize modal bandwidth ntawm fiber ntau. Lawv txhawb ib leeg-channel 100G VCSEL optical modules ntawm kev sib kis ntawm 80 meters thiab 100 meters. Lawv kuj txhawb Terabit BiDi MSA (xws li, 800GSR4.2, 1.6TSR8.2) dual-wavelength transceivers, ua tiav kev sib kis ntev dua li tus qauv OM3 / OM4 fibers ntawm wavelengths ntawm 850nm thiab 910nm.

 

HDR OM3 fiber ntau txhais tau qhov tsawg kawg nkaus EMB tus nqi ntawm 2890 MHz ·km ntawm 850nm, uas poob rau hauv thaj tsam ntawm OM3 fiber ntau EMB (2000 MHz·km txog 4700 MHz·km), nrog rau ntau dua ntawm OM3 fibers ua tau raws li qhov xav tau ntawm HDR OM3. . Qhov no pab tsim kom muaj peev xwm, muaj txiaj ntsig zoo rau VCSEL lasers / multimode optical fibers. HDR OM3 fiber ntau txhawb kev sib kis deb ntawm 80 meters ntawm ib leeg-channel 100G tus nqi, ua tau raws li qhov yuav tsum tau muaj ntawm ntau qhov xwm txheej fiber ntau. Piv nrog rau kev siv OM4 fibers, nws tuaj yeem txo tus nqi tag nrho ntawm kev sib txuas ntawm ntau hom kev daws teeb meem.

 

Tsab ntawv xov xwm tseem tau taw qhia tias HDR OM3 / OM4 fibers txhais cov ntsuas bandwidth rau 910nm. Lawv txhawb kev siv dual-wavelength transceivers ntawm 850nm thiab 910nm hauv Terabit BiDi MSA, ua tiav kev sib kis ntawm 80 meters thiab 100 meters, feem. Qhov no sawv cev rau kev txhim kho ntawm 77 feem pua ​​​​thiab 43 feem pua ​​​​ntawm cov qauv OM3 / OM4 fibers. Tsis tas li ntawd, kev sib kis ntawm HDR OM4 mus txog qib OM5 (100 meters) hauv kev txhawb nqa Terabit BiDi transceivers.
