This allows both connections in the DLR as well as the redundant coupling with higher-level layer-3 structures to be implemented flexibly in an application with up to four fiberglass connections. Thanks to the wide selection of SFP fiberglass modules, single and multimode connections are possible with conductor lengths of up to 80km. The switches are therefore suitable as an interface between the production network and automation cell, or when a free choice of transmission medium is important.
Support for the RSTP and DLR protocols ensures consistent redundancy throughout the entire system.
