Applications such as public mass transport system control and monitoring require a serial fiber network to deliver signals fast and accurately with the high noise immunity, high signal quality, long networking range and isolation surge protection. The Korenix JetCon 2401 serial fiber converter provides an effective solution in combination with legacy RS-232/422/485 serial devices or with GE Fanuc Genius Serial Bus PLCs.Via a pair of JetCon 2401-s serial-fiber converters with single media mode, Korenix extends the control range of Genius Serial Bus of GE Fanuc PLCs by up to 40 kilometers, a significant enhancement compared with the maximum length of twisted-pair cable run of 2283 meters.In testing, two JetCon 2401-s units endured a heavy load of signal transmission by wiring 22 GE VersaMax PLC units in multidrop connection of Genius Serial Bus with a GE Fanuc SERIES 90-30 CPU-364 module. Connecting the serial fiber network with two JetCon 2401 serial fiber converters in single media mode in between the 90-30 CPU and the first VersaMax PLC unit, the serial signal propagation delays of Genius Serial Bus measured in 440 nanoseconds with control signal running at 153.6Kb baud rate.
