PRS-FINS Fiber Interface

Description

Most of the Praesideo system units have plastic fiber optic interfaces. Plastic fiber is used to interconnect nodes which are less than 50 meters apart. For distances of more than 50 meters glass fiber optic cable is used. A fiber interface converts from plastic to glass fiber and vice versa. The fiber interfaces have a power supply input to provide power to remote network sections and two control inputs. The control inputs can pass on supervision information about the power supply connected to the fiber interface.
