• Support multi‑axis motion control with stable, low‑error data transfer

• Designed for long‑distance external routing between separated machine cabinets

5. Installation Instructions

1. Power Off: Connect/disconnect only when system power is fully cut off.

2. Bending: Do not bend sharply; maintain ≥35 mm bending radius.

3. Connector Care: Keep end faces clean, dry, and free of dust/contamination.

4. Routing: Avoid running near high‑voltage cables or strong EMI sources.

5. Protection: Use cable trays/ducts for external runs; avoid direct chemical/extreme heat exposure.

6. Replacement: Use only FANUC original fiber cables; do not substitute with Ethernet or generic fiber.

7. No Cutting: Do not cut or extend the cable; select the correct length for your application.
