Serial Modules for Long Distances
Application
The optical protection-interface modules are used for long distances over multimode or singlemode optical
fibers. In the case of the protection interface, they serve the purpose of point-to-point transmission between 2
devices. One possible application is the transmission of differential protection data. For example, if you wish
to transmit only binary data and measured values, you can equip all SIPROTEC devices with these protection
interfaces.
