Fujitsu and Indiana University (IU) have released the results of an advanced optical networking research, which showed that fiber’s Polarization Dependent Loss (PDL) can have a considerable effect on 100 Gbps and 40 Gbps transmission capability.
IU provided Fujitsu access to both aerial and buried fibers so that the measurement of Polarization Dependent Loss can be done in a real-world environment. The research proved that Polarization Dependent Splice Loss (PDSL) exists and further research linked the fiber connection loss and PDSL to Polarization Dependent Loss.
IU Global NOC offers operation and engineering services for global research and education networks and IU’s fiber optic networks. It also supports grid operations and provides equipment and dark fiber for research experiments.
Fujitsu has invested $2.6 billion for R&D projects to develop new, sophisticated technologies for optical networks and computer servers.
The Director of Fujitsu Laboratories of America, Motoyoshi Sekiya, stated that IU enabled the company to conduct research in real-world environment and helped them to make new discoveries. Such findings can accelerate the adoption of advanced communication products.
IU’s Chief Network Architect, Matt Davy, stated that collaborating with Fujitsu allowed the institute to gain real-time experience and experimentation data with next-generation technologies.
