The LD-64 can be used to provide a redundant fibre optic ring solution for equipment with RS-232/V.24 or RS-422/485 interfaces. The LD-64 is mostly used in applications were high reliability is required as this unit can still function even if a fibre or a fibre pair are broken. In the event of line failure the LD-64 is equipped with alarm outputs which can be connected to a local I/O device (a PLC) to provide a network alarm. The LD-64 handles transmission rates up to 375 kbit/s. It is available in both multi- and single mode fibre.
