Extend & Stabilize CAN Networks: Comark's Fiber Optic Repeater Solution

1. Why Your CAN Network Fails?

CAN bus, the "nervous system" of industrial communication, offers high reliability but faces:
✅ Short Distance: General CAN supports only hundreds of meters—insufficient for large factories/ships.
✅ Signal Interference: EMI, ground loops, and lightning strikes disrupt operations.
✅ High Maintenance Costs: Downtime and data loss drain resources.

2. Comark's CI-AF  Series Fiber Optic Repeater: Your Stability Guardian
     1️⃣ Extend Range:

• Multimode fiber: 2km | Singlemode fiber: 40km

• Covers plants, vessels, wind farms effortlessly.
  2️⃣ Eliminate Interference:

• 4,000V lightning protection → Survives storms.

• Blocks EMI/ground loops → Zero packet loss.
  3️⃣ Industrial Durability:

• Isolated redundant power (9-36V DC) → No crashes during voltage fluctuations.

• Real-time fault alerts → Doubles maintenance efficiency.
