摘要:This paper describes the installation, commissioning and testing of the 4 Gigabit Lightpath from
Onsala to Jodrell bank which is being used as part of the EXPReS project to send data from the
telescope at Onsala to the new WIDAR correlator at Jodrell Bank. The network path is truly
multi-domain, it crosses multiple administrative domains, uses equipment from different
manufacturers, and both Ethernet and SDH framing technologies are used on different portions
of the path. Measurements performed using both PC and deterministic Field Programmable Gate
Array techniques are described and results on the performance and stability of the 4 Gigabit path
are shown. Finally, plots demonstrating the successful sampling and movement of data from the
telescope to the correlator are presented.
