Material Composition Industrial‑grade optical fiber core. Reinforced tensile fiber layer. Flame‑retardant and wear‑resistant outer jacket. Precision‑molded plastic optical fiber connectors at both ends.
Structural Characteristics Flexible cable structure with fixed length. Both ends equipped with dedicated optical connectors for direct plug‑in connection. Outer jacket provides mechanical protection. Weight approximately 0.09 kilogram.
Working Principle Electrical signal from sending‑end board is converted into optical signal, transmitted through optical fiber cable. Optical signal reaches receiving end and is converted back into electrical signal. Optical transmission path does not conduct electricity, so high‑voltage and electromagnetic interference cannot pass through the link.
Installation Requirements Confirm power equipment is fully powered‑off before replacement. Insert optical connectors firmly into corresponding optical ports of two‑side boards. Reserve reasonable bending radius for optical fiber cable. Fix cable with cable tie without excessive extrusion. Verify optical communication link after power‑on.
Usage Notes Do not bend optical fiber cable below minimum bending radius. Prevent scratch, extrusion and tensile damage to cable and connectors. Keep connector end face clean, avoid dust contamination. Do not touch optical fiber core directly.
