Cov kev cai tshwj xeeb rau cov kab hluav taws xob kho qhov muag hauv AI cov chaw zov me nyuam

Kev tawg ntawm AI cov chaw zov me nyuam (cov chaw siv computer ntse) yog qhov hloov kho cov qauv kev sib txuas network tag nrho. Tus nqi ntawm kev sib txuas ntawm cov khoom siv kho qhov muag siv yog 5 mus rau 10 npaug ntawm cov ntaub ntawv ib txwm siv. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua kom nruj ntawm kev xa tawm siab thiab xoom pob ntawv poob rau kaum tawm txhiab tus GPU pawg, AI cov ntaub ntawv chaw tau muab rau plaub qhov kev cai nruj heev rau cov khoom siv kho qhov muag:

1. Extreme space density: smaller, denser, and softer. Qhov chaw hauv AI racks thiab cov kav dej yog qhov tsawg heev, thiab ib qho kev hloov pauv yuav xav tau kom haum ntau dua 20,000 fibers optical. Miniaturized sab nraud txoj kab uas hla: Nws yog feem ntau yuav tsum tau siv 200 micron sab nraud txoj kab uas hla coated optical fiber (ib txwm 250 micron), thiab tag nrho cov thickness ntawm cov kho qhov muag cable yuav txo tau mus txog 60% kom alleviate cable trough congestion thiab xyuas kom meej cua kub dissipation. Cov qauv ribbon tshiab: Mainstream kev saws me nyuam ntawm cov ribbon hloov tau yooj yim cable technologies xws li Corning's Flow Ribbon tau ua rau kom cov bundled cores ntawm micro- kho qhov muag cables nyob rau hauv lub pipeline. Bending insensitivity: Rau siab - fibers optical ceev nyob rau hauv ib tug txwv txee qhov chaw, G.657.A1 los yog G.657.A2 qib khoov-insensitive optical fiber yuav tsum tau siv los xyuas kom meej tias tsis muaj teeb meem pom tseeb dabtsi yog khoov poob yog tshwm sim ntawm ib tug me me dabtsi yog khoov vojvoog.

2. Kev ua haujlwm tshwj xeeb raws li CPO architecture: kev saib xyuas polarization thiab poob qis. Raws li kev suav fais fab hloov mus rau 800G thiab 1.6T, qhov sib kis ntawm cov kab hluav taws xob ib txwm siv (DAC) tsuas yog tsawg dua 3 meters, thiab photoelectric co- ntim (CPO) thev naus laus zis tau dhau los ua qhov tseem ceeb. Loj - nplai daim ntawv thov ntawm polarization- tuav fiber ntau (PMF): Kev sib raug zoo ntawm lub teeb sab nraud thiab cov silicon photonic nti nyob rau hauv CPO architecture yog qhov tsis tshua muaj siab rau lub xeev polarization ntawm lub teeb. Raws li kev lag luam tso cai tsom xam, qhov kev thov rau polarization- tuav cov fiber ntau hauv cov chaw siv computer ntse tau ntsib kev loj hlob ntawm 10 mus rau 20 zaug kom ntseeg tau tias muaj kev sib txuas ruaj khov thiab txwv tsis pub nkag mus. Qhov loj siv tau zoo thiab ultra- poob qis: Cov qauv kev cob qhia loj yuav tsum muaj kev tswj xyuas lub zog siab rau lub sijhawm ntev. Cov fiber ntau kho qhov muag yuav tsum muaj thaj chaw ua haujlwm loj los tiv thaiv cov teebmeem uas tsis yog-linear, thiab yuav tsum muaj ultra-tsawg poob (ULL) kev ua tau zoo los txo qhov kev siv zog tag nrho ntawm qhov txuas.

3. Hla-kev sib txuas hauv tsev kawm ntawv (DCI) qis heev-latency AI faib kev cob qhia yuav tsum kom lub network ncua ntawm tus ntoo khaub lig-cov chaw zov me nyuam (DCI) yog infinitely ze rau xoom. Hollow core fiber (HCF): Raws li kev cuam tshuam thev naus laus zis hauv AI era, kev sib kis ceev ntawm lub teeb hauv huab cua ntawm hollow fiber ntau yog li 35% sai dua li cov iav quartz ib txwm muaj. Qhov no tuaj yeem txo cov latency network ntau dua 30% thiab muaj ultra-siab zog kam rau ua.

4. High-kev tsim khoom thiab cov khoom siv technology, precision dispensing thiab kev ntseeg siab: Vim tias AI optical fiber ntau yog qhov zoo heev thiab ntom, cov tuam txhab kho qhov muag loj (xws li YOFC, FiberHome Communications) tau qhia siab -cov kua xa tawm cov txheej txheem xws li Nordson EFD (Nordson) loj loj rau hauv txhua qhov kev tsim khoom loj { optical fiber bonding point muaj cov neeg kho tshuab kev ntseeg siab heev thiab ntev -lub sij hawm stability.
