We report on the upgrade of a fiber optic network for time and frequency transfer between PTB in Braunschweig and the test center of Deutsche Telekom in Bremen, Germany. The network provides 10 MHz and 1 PPS signals at remote locations intended for the supervision of the mobile telecommunication network of Deutsche Telekom. Here we present the results of the time transfer calibration of the link.
The OPTIME project creates an ultra-precise time and frequency signals dissemination system based on telecommunication networks. End users obtain access to these signals without incurring huge costs for the purchase of their own atomic clocks, and receive the service related to laboratories generating international atomic time scales, to which any precise time must be referred. This document describes...
The main goal of OPTIME project is to design and to create an infrastructure for a long range dissemination system for transfer of ultraprecise time scale and reference frequency signals in telecommunication networks. OPTIME dissemination system is based on three main elements: reference time and frequency laboratories, local time and frequency repositories and fiber optical network with specialized...
