Tuam Tshoj tus Thawj Display Quantum Secure Kev Sib Txhawj ntawm Fiber Backbone
Kev siv cov kabmob fiber ntau optic cable chaw yuav tsum tau ua kom ncav tau cov kev sib txuas lus ruaj ntseg - Tuam Tshoj tus thawj cov qauv ntawm cov ntsiab lus tseem ceeb ntawm cov ntu thiab cov kab sib dhos ntawm qhov ntev 3.6Tbps kev sib txuas lus lag luam fiber ntau qaum network
Raws li Science thiab Technology Txhua Hefei Lub Peb Hlis 9 : Tus nyeem tau kawm los ntawm Hefei High-tech Zone tias Guodun Quantum koom tes nrog University of Science thiab Technology ntawm Tuam Tshoj, Jinan lub koom haum ntawm Quantum Technology, thiab Tuam Tshoj Unicom qhia txog nws txoj kab nruab ntug qhov tseem ceeb qaum kev network rau qhov tseem ceeb quantum faib (QKD) thiab 3.6Tbps kev sib txuas lus rau thawj zaug nyob hauv lub ntiaj teb. T nws tau raug luam tawm nyob rau hauv phau ntawv "Optical Express" magazine rau Lub Peb Hlis 5.
Hauv txoj kev tshawb no, QRD khoom siv ntawm Guodun Quantum Co., Ltd. tau siv, thiab thawj thawj zaug, wavelength division multiplexing ntawm optical fiber ntawm 66km (Zhucheng-Huangshan seem) ntawm QKD thiab chaw lag luam optical fiber ntau lag luam network (Tuam Tshoj Unicom lub Jinan-Qingdao network) tau pom tau hais. Tus nqi yog 3.6 Tbps, qhov siab tshaj plaws tawm qhov muag fais fab tuag yog 21dBm, thiab spectral ntau yog 1528-1538nm.
Tsis tas li ntawd, nyob rau hauv ib tug qauv ib hom fiber ntau, siv lim lim ntawm 20 GHz, QKD tau ua tiav ib qho coding tus nqi ntawm 3.0 kbps nyob rau tib qho kev sib txuas ntawm kev sib txuas nrog kev sib txuas lus classical. Ua ke nrog cov tshiab loj G654 qes-tsawg fiber ntau, QKD coding tus nqi yuav ntxiv ntxiv rau 4.5 kbps thiab 5.1 kbps hauv tib kis tau tus mob thiab rov qab kis, feem. Kev sim ua qauv thiab kev ntsuam xyuas ntawm cov teebmeem ntawm cov khoom siv bandwidth, fiber ntau, thiab fiber ntau thaj tsam ntawm quantum teeb liab-rau-suab nrov thiab kev ruaj ntseg coding tus nqi. Nyob rau tib lub sijhawm, los ntawm cov kev xeem ntev ntawm kev ua haujlwm ntawm QKD coding tus nqi, qhov kev sim no qhia qhov kev ruaj ntseg ntawm QKD qhov system hauv wavelength division multiplexing nrog lub lag luam kev lag luam kev sib koom tes.
Rau thawj thawj zaug, qhov kev sim no siv lub lag luam fiber ntau ntawm kev lag luam, qhia qhov tsis yooj yim ntawm kev sib txuas lus ntawm kev sib txuas lus, lub zog siab dua lub teeb, Raman nrov nrawm nrov, thiab ntau yam hauv thaj tsam ntawm qhov chaw kawm, rau qhov kev paub ntawm QKD thiab cov ntawv thov kev lag luam. Kev rov qab kho qhov muag ntawm fiber ntau qaum kev sib txuas lus tes hauj lwm tau siv lub kauj ruam tseem ceeb heev rau txoj kev tsim ib tus nqi quantum network uas sib koom tes nrog cov kev lag luam uas muaj kab mob qaum ntawm cov khoom qub.
OPTICO COMMUNICATION (www.fiberopticom.com) tsom rua kev tsim cov khoom siv fiber ntau ntawm fiber ntau thiab muab kev daws teeb meem rau cov khoom siv fiber ntau txuas. Peb muab fiber ntau optic Cheebtsam. Tag nrho cov khoom siv txais cov qauv zoo nruj hauv kev tsim thiab kev soj ntsuam, kom ntseeg tau zoo heev thiab ua kom cov khoom ruaj khov zoo, thiab xyuam xim thiab muaj kev ruaj ntseg zoo rau kev siv lub sij hawm ntev.
