With the increase in operation length, the corresponding demands for communication devices for rail transit keep increasing.
Optical cables are widely used in rail transit for their excellent safety, electromagnetic compatibility, reliability, multi-interfaces, and extensibility. Meanwhile, the security of rail transit has become more and more critical.
For the optical cables, the most severe accident is fire. Once the cable is damaged by fire, the communication might be interrupted, making it impossible to monitor the signals and control the essential devices, thus making it difficult for rescue, real-time monitoring, and equipment control.
Therefore, the communication cables are required to guarantee regular communication in the case of emergencies.
Based on flame-retardant & fire-resistant optical cables, ZION has developed optical cables for rail transit.
The cables can maintain regular communication and operation of critical equipment, send alarms and minimize losses caused by fire.
