The LD-64FD can be used to provide a redundant fiber optic ring solution for equipment with RS-232/V.24 interface. The LD-64FD is mostly used in applications were high reliability is required as this unit can still function even if a
fiber or a fiber pair are broken. In event of line failure the LD-64FD is equipped with alarm outputs which can be connected to a local I/O device (a PLC) to provide a network alarm. The LD-64FD provides full duplex communication and is specially developed for master/slave protocols which demands that slaves will not receive data from other slaves.
