Selection Guide & FAQ

• Selection Advice: Use the 1783-ETAP2F when your network segment exceeds the 100-meter limit of copper cabling.
• Selection Advice: Ensure your power supply meets SELV/Class 2 standards to maintain isolation integrity.

• Question: What is the advantage of using LC connectors on the 1783-ETAP2F?
• Answer: The LC connector provides a small form factor with a secure locking mechanism, reducing the footprint in crowded enclosures.

• Question: Can I mix different fiber types with this tap module?
• Answer: While it supports 62.5 and 50 μm fiber, the power budget changes. Always match the fiber type across the entire channel length.

• Question: Is an external power supply required for the 1783-ETAP2F?
• Answer: Yes. As an open-style device, it does not draw power from a backplane and needs a local 24V DC source.

• Question: How does the "Auto-Negotiating" copper port benefit my system?
• Answer: It automatically detects speed (10/100 Mbps) and duplex mode, ensuring compatibility with various industrial Ethernet devices.

• Question: What are the specific clearance requirements for mounting?
• Answer: Maintain 3 inches of space at the bottom and 1 inch on the remaining sides to ensure proper cooling and wiring access.
