L'\u00e9quipement de transfert de temps de haute pr\u00e9cision T900-P \u00e0 fibre optique est un syst\u00e8me de chronom\u00e9trage de haute pr\u00e9cision bas\u00e9 sur une liaison WDM, et le syst\u00e8me est divis\u00e9 en deux parties : la station centrale et la station terminale. La station centrale de chronom\u00e9trage se compose principalement d'une unit\u00e9 d'interface temps-fr\u00e9quence, d'une unit\u00e9 de mesure du temps-fr\u00e9quence, d'une unit\u00e9 d'encapsulation du signal temps-fr\u00e9quence, d'une unit\u00e9 de conversion optique\/\u00e9lectrique et \u00e9lectrique\/optique, et d'une unit\u00e9 de multiplexage et de d\u00e9multiplexage de la longueur d'onde. La station terminale de synchronisation se compose d'unit\u00e9s de multiplexage et de d\u00e9multiplexage des longueurs d'onde, d'unit\u00e9s de conversion optique\/\u00e9lectrique et \u00e9lectrique\/optique et d'unit\u00e9s d'asservissement pour la mesure du temps-fr\u00e9quence. Le syst\u00e8me de synchronisation utilise la m\u00e9thode classique de comparaison temporelle bidirectionnelle et s'appuie sur le canal de fibre optique (canal de longueur d'onde DWDM) pour r\u00e9aliser une synchronisation temps-fr\u00e9quence de haute pr\u00e9cision. L'\u00e9quipement fonctionne de mani\u00e8re stable et est tr\u00e8s r\u00e9sistant aux interf\u00e9rences. Il peut atteindre une pr\u00e9cision de synchronisation de 50ps sur 100 km.<\/p>\n

Le T900-P est un dispositif de transfert de temps de haute pr\u00e9cision par fibre optique bas\u00e9 sur une liaison WDM, adoptant une architecture de station centrale et de station terminale, combin\u00e9e \u00e0 une technologie de comparaison de temps bidirectionnelle, pour r\u00e9aliser une synchronisation temps-fr\u00e9quence stable et anti-interf\u00e9rence dans un canal DWDM. Le syst\u00e8me supporte une distance de transmission de 100 km avec une pr\u00e9cision de synchronisation sup\u00e9rieure \u00e0 40ps. Il est largement utilis\u00e9 dans les sc\u00e9narios de synchronisation de haute pr\u00e9cision tels que l'exploration de l'espace lointain, la d\u00e9fense nationale et la recherche scientifique.<\/p>","protected":false},"featured_media":3995,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[54],"product_tag":[],"class_list":{"0":"post-3967","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-54","7":"pa_--pps-todnmea-0183","8":"pa_-197","9":"pa_----2u","10":"pa_--0-c--70-c","11":"pa_-military-aviation","12":"pa_-metrology-and-testing","13":"pa_-communications-infrastructure","14":"pa_-229","15":"pa_-10mhz-sine-wave-square-wave-output","16":"pa_-irig-bdcls-am","17":"pa_-todrs-232-nmea","18":"pa_-ac-220v","19":"desktop-align-left","20":"tablet-align-left","21":"mobile-align-left","22":"ast-product-gallery-layout-first-image-large","23":"ast-product-gallery-with-no-image","24":"ast-product-tabs-layout-horizontal","26":"first","27":"instock","28":"shipping-taxable","29":"product-type-simple"},"acf":[],"yoast_head":"\n
