Exceptionally fault-tolerant dual-loop optical cable
- Reduce the noise influence
- Maintain communications during an error
Highly-reliable loop topology
Fault-tolerant network
Dual-loop optical cables that provide noise-immunity to Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) are used. These robust cables include a loop-back function which ensures data communication even when there is a cable disconnection or the power supply is lost. In addition, an external power supply can be connected to modules supporting this feature, ensuring communications even if connection to the controller or computer is lost.
