Description
Summary:Owing to the characteristics of ultralow loss and antielectromagnetic interference, using optical fiber to deliver time and frequency signals has been a preferred choice for high-precision clock dissemination and comparison. As a brilliant idea, one has been able to reproduce ultrastable signals from one local station to multiple users. In this paper, we take a step further and propose a concept of multiclock (in different locations) dissemination for multiterminals. By injecting frequency signals into one stabilized ring-like fiber network, the relative stabilities of 3.4 &#x00D7; 10<sup>&#x2212;14</sup>&#x0040;1 s for a master clock dissemination and 5.1 &#x00D7; 10<sup>&#x2212;14 </sup>&#x0040;1 s for a slave clock dissemination have been achieved. The proposed scheme can greatly simplify the future &#x201C;N&#x201D; to &#x201C;N&#x201D; radio-frequency dissemination network, especially in the situation of multiclock comparison.
