SPC X-Bus RS485 to Fiber Converters

The FDX60 multimode fiber units allow the X-Bus transmission to be converted from 485 protocol to optical and back to 485. This allow the data between the SPC expanders to travel further distances. (max 4.5Km). It is recommended to use a maximum of 3 pairs per data channel or 3 pairs in the overall X-Bus data loop.

SPC X-Bus RS485 to Fiber Converters

The ComNet FDX60(M,S)[-M] data transceivers provide point-to-point transmission of simplex or duplex EIA RS232/RS422/RS485 (2W/4W) data signals over one or two optical fibers. The transceivers are transparent to data encoding allowing for broad-range compatibility. Models within this series are available for use with multimode or single mode optical fiber.
