OverviewFeaturesSpecificationApplicationOrder Information
TFM321-2F-FR single-channel dual-loop self-healing industrial fiber modem is a low-cost serial data transmission communication device
with dual-ring self-healing function that can adapt to industrial environments. It can form a chain network or a dual-loop fiber network to
realize transparent transmission of one RS-232/RS-485/RS-422 on the fiber ring network without changing the user agreement
-
Supports fast ring network redundancy function;
-
PCM pulse code modulation technology combined with digital phase-locked loop clock extraction technology;
-
Serial protection circuit, hot-swappable;
-
Serial access node greater than 128;
-
Smart electrical interface, no dial setting;
-
Perfect status indication, LED light alarm, easy maintenance and troubleshooting
