Txuj ci

Nyob rau hauv Niaj hnub no lub ntiaj teb cov ntaub ntawv tawg kev loj hlob, cov ntaub ntawv thoob ntiaj teb ib yam tau tshaj 500, {tus tub ntxhais ib leeg kis ib leeg muaj peev xwm kis tau zoo rau lub shannon txwv. Ntau cov tub ntxhais muaj fiber ntau (MCF), los ntawm kev sib txuas ntau txoj kev sib txuas lus nyob hauv ib qho "txoj kab kev sib txuas" mus rau qhov tseem ceeb thev naus laus zis los tsoo cov peev txheej bottlenecks. Cov kab lus no nthuav tawm cov kev tsis paub txog ntawm no kev hloov kho tshuab los ntawm peb qhov ntev: cov yam ntxwv kev ua, cov tseem ceeb ntawm cov xwm txheej.

Kuv. Cov yam ntxwv ntawm ntau txoj haujlwm fiber ntau

Peb-seem spatial multiplexing architecture
Ntau cov tub ntxhais muaj ntau lub Cores ywj siab (feem ntau 4-19) nyob rau hauv tus qauv ntawm lub cheeb ntawm 125 μm. Piv txwv li, xya tus tub ntxhais kawm tau txais txiaj ntsig rau hexagonal kaw-rau-nruab nrab ntawm ib tug tib neeg cov plaub hau), ua tiav rau hauv cov ntsiab lus tseem ceeb piv rau cov tsoos fibers.

Chaw Saib Xyuas Tshwj Xeeb Tshaj Tawm (SDM) Technology
Los ntawm kev faib tawm cov kis tau raws caij raws cov nplaim hluav taws xob, txhua tus tseem ceeb ntawm cov cim sib txawv. Combined with ‌mode multiplexing‌ (supporting multiple optical modes per core) and ‌wavelength division multiplexing‌ (C+L band expansion), this creates a "space × mode × wavelength" three-dimensional multiplexing system, theoretically boosting capacity by ‌100x‌.

Ultra-Low Crosstalk Tsim
Lub trench-pab tsim qauv yog ua haujlwm: Annular cov trenches etched ntawm cores nrog qhov tob ntawm 2-5 μm thiab qhov ntsuas qhov ntsuas qis dua li cov cladding. Coupled nrog heterogeneous cov tub ntxhais ntawm cov diametal / refression index / k} db /} DB /} DB / Defpressent

Txawj ntse sib xyaw
Kev sib xyaw ua ke nrog cov tub ntxhais tub ntxhais cov tub ntxhais muaj zog siv los ntawm cov khoom siv sib txuas thiab ib leeg-tawm (Fifing Fiber ntau dua
