The LD-64 can be used to provide a redundant fiber 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
fiber or a fiber 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 is available in two version, low speed (LD-64) which handles transmission rates up to 375 kbit/s and high speed (LD-64F) which handles transmission rates from 500 kbit/s up to 1.5 Mbit/s. Both versions are available for both multi- and single mode
fiber.
