Taw qhia: Thaum lub teeb mus los ntawm huab cua
Hauv kev saib xyuas kho qhov muag pom zoo, cov paib teeb pom kev hais tawm los ntawm cov iav tub ntxhais, tsuas txwv los ntawm cov khoom nonlineEarity thiab latency. Hollow-Core fiber ntau (HCF) Qhov paradigm no travels los ntawm huab cua hauv lub tshuab nqus dej nrawm (30% sai dua!), Nrog ze-xoom tsis muaj kev poob. Raws li muaj cov kws ua haujlwm muaj fiber ntau, Kuv yuav coj koj los ntawm qhov tseeb 2023 tawg thiab kev ua lag luam nyuaj ntawm qhov no "cov thev naus laus zis."
Tshooj 1: Kev Tawm Tsam-HCF peb qhov kev ua si-hloov cov txiaj ntsig
1.1 physics-defying kev ua tau zoo
Kev ua kom zoo dua: Kev Tshaj Tawm Cov Kev Tshaj Tawm Txog 299,792 km / s (vs. 204,190 km / s nyob rau hauv ib txwm fiber ntau), txo latency los ntawm 31.6%.
Ultra-Low Nonlinearity: Huab cua Core tshem tawm cov kerr teebmeem, txhawb 10x siab dua hwj chim (twb ua tiav 5kw laser kis).
Hluav Taws Xob Kuj: Cov paib kev ua kom nyob hauv thaj chaw ib puag ncig yog 1, {1}} x qis dua li cov fiber ntau.

Kis mus deb surpassed 10 km (Microsoft Azure & Lumenisity's ib-hom, Rephuav sim).
Ntau tus tub ntxhais HCF: NTT ua tiav 19- sore tseem ceeb hcf nrog muaj peev xwm ntom ntawm 1.5 PBPS / MMP.

Tshooj 2: Cov ntawv thov-ntawm Lab Mus Rau Lub Ntiaj Teb Tiag
2.1 ultra-qis latency nyiaj txiag sib koom tes
Cov ntaub ntawv: Chicago↔nnyc high-frecency trading kab txo tau latency rau 28.5ms (vs. 41.2ms nrog cov fiber ntau).
Tus nqi: $ 120 lab / xyoo cov sij hawm txiav txim siab rau ib 1ms nce (Goldman Sachs 2023 kev kwv yees sab hauv).
2.2 High-High Muaj Zog Tsav Tsheb Laser
Kev tawg: Trumpf (Lub teb chaws Yelemees) siv HCF los xa cov lasers rau Aerospace titanium vuam).
Ntug: xoom thermal lensing, tshem tawm fiber ntau-end burnout nyob rau hauv ib txwm muaj.
2.3 Qhov Chaw Sib Txuas Lus Tawm
NASA kuaj: Artemis Lunar Reints saws HCF, txhawb hluav taws xob tiv thaiv hluav taws xob los ntawm 1, {1}} x.
Cov Ntaub Ntawv Tus Nqi: 100GBps Lub Ntiaj Teb-Moon Kis nrog Ber<10⁻¹².
Feem 3: Kev Lag Luam Kev Lag Luam & Kev Txhim Kho Kev Txhim Kho
3.1 Raug Hurdles
Mob Qhov Mob: Photonic Bandgap qauv yuav tsum tau sub-micron precision (yuam kev<50nm), yield rate just 35%.
Nrhav:
Femtosecond laser 3D printing (femtoprint, Switzerland).
Tus kheej-ua ke nano cov xim mos (mit's atomic-txheej alumina tso nyiaj).
3.2 fusion splicing sib ntaus sib tua
Cov xwm txheej: HCF↔SMF Splice poob txog 2dB.
Kev daws teeb meem:
Tapered Transition Fibers (OFSS PATIC).
Ntshav-ua haujlwm Spricing (Fujikura fs -130 +} dua).
3.3 Cov nqi Cliff Nkhaus
Tus nqi tam sim no:
5 {0 0 / metre (vs.500 / metre (vsh0.3 / meter rau ib txwm fiber ntau).
Txoj kev txiav nqi:
Pawg ntau lawm: Lumenisity lub Hoobkas tshiab Hoobkas $ 50 / 'meter txog 2025.
Cov khoom sib pauv khoom: Silica → polymer-raws HCF (UNIV. NTAWM SOUNDAMPTON PROTOTYPE).
Ntu 4: Txoj kev yav tom ntej ntawm txoj kev kaus hniav -2030 lub zeem muag
Cov hom phiaj ua tau:
Attenuation tsawg dua los yog sib npaug rau 0. 15 db / km (txuam nrog fiber ntau).
Ib-fiber muaj peev xwm ntau dua los yog sib npaug rau 1 PBPS (Full C + L + S BAND SIV).
Kev Siv Siv Kev Siv Siv:
Quantum Kev Sib Tham: Photon Lub Xeev ncaj ncees ↑ rau 99.99%.
Lub hlwb-tshuab cuam tshuam: submicron hcf nkag siab cov ntshav-hlwb teeb meem.
Kws ua choj txoj kev npaj ua
