چکیده

Abstract We introduce multi-branch repeater laser stations (MLSs) for the dissemination of an ultra-stable signal from one point to multiple users and simultaneous evaluation stability accuracy links. perform study noise floor this new instrument. present then optical fiber network 4800 km built with three MLSs 13 (RLSs). show multi-user frequency on four links totalizing 2198 uncertainties below 1.1 × 10 ?19 . The robustness over two years is presented at 7 seconds integration time are finally showed.

Frequency dissemination with free-space optical links

Optical clock technology is very certain to be integrated in the next high precision time standards. The demand for higher accuracy in time synchronization makes the use of free-space optical links necessary for frequency dissemination, especially if mobile partners are involved. These links are the most suitable solution in order to disseminate high frequencies in between satellites, ground st...

Cascaded multiplexed optical link on a telecommunication network for frequency dissemination.

We demonstrate a cascaded optical link for ultrastable frequency dissemination comprised of two compensated links of 150 km and a repeater station. Each link includes 114 km of Internet fiber simultaneously carrying data traffic through a dense wavelength division multiplexing technology, and passes through two routing centers of the telecommunication network. The optical reference signal is in...

Coherent optical orthogonal frequency division multiplexing

Introduction: Orthogonal frequency division multiplexing (OFDM) has been extensively investigated to combat RF microwave multipath fading, and has been widely implemented in various digital communication standards such as wireless local area network standards (WIFI IEEE 802.11a) [1]. In this Letter, we propose an optical equivalent of the RF OFDM called coherent optical OFDM (CO-OFDM) to combat...
