Fiber optic repeaters ensure stable, reliable long-distance signal transmission by acting as "signal translators and amplifiers":
1️⃣ Signal Conversion: Precisely convert electrical signals → optical signals for fiber transmission.
2️⃣ Long-Distance Transport: Near-zero-loss optical transmission (up to 10-20 km).
3️⃣ Signal Restoration: Reconvert optical → electrical signals at endpoints to drive devices.
Flexible Deployment Modes：
✅ Point-to-Point: Connect PLCs/VFDs/sensors beyond distance limits.
✅ Tandem Networking: Extend coverage via multiple repeaters.
✅ EMI-Shielded Zones: Install near VFD/HV equipment.
Harsh Environments: High humidity, condensation, EMI, and high voltage demand:
EMI immunity ️
Water/dust resistance
Disaster resilience ️
Analog Signal Challenges (4-20mA/0-10V):
±0.1% Linearity: True-to-source data fidelity.
EMI Isolation: Fiber eliminates noise.
Multi-Signal Support: Current/voltage/thermocouples.
Zero-Configuration: Plug-and-play operation.
