Connect the copper conductors of the composite cable to a DC power source using terminal blocks or crimp connectors, ensuring correct polarity and secure connections while keeping the fiber optic strands intact.

Step-by-Step Guide

1. Prepare the Cable

• Route the composite cable through the intended path, such as a distribution box or conduit, ensuring it is free from sharp bends or kinks .
• Strip the outer jacket of the cable to expose the copper conductors, leaving about 5–8 mm of insulation on each wire . 2. Identify Polarity
• Determine the positive (usually red) and negative (usually black) copper wires within the composite cable .
• Correct polarity is crucial to prevent damage to connected devices. 3. Connect to Terminal Blocks or Crimp Connectors
• For terminal blocks: Insert the stripped copper wires into the corresponding DC terminal block slots and tighten the screws securely .
• For crimp connectors: Slide the crimp tube over the copper wire, press it firmly with a crimping tool, and ensure no copper strands are exposed . 4. Integrate with Devices
• Connect the other end of the copper conductors to the power input of the device (e.g., IP camera, media converter) or to a PoE media converter capable of delivering low-voltage DC power .
• Ensure the fiber optic strands are connected separately to the appropriate LC adapters or SFP modules for data transmission . 5. Secure and Test
• Use cable clamps or hangers to secure the cable along its route, preventing strain on the connections .
• Power on the system and verify that the device receives power and functions correctly.
• Optionally, test the optical fiber for signal integrity using a power meter or optical loss test to ensure proper data transmission .

Safety and Best Practices

• Always use a power supply within the voltage range specified for the cable and connected devices (commonly 24–57 V DC for hybrid cables), .
• Avoid exposing copper wires to moisture; use waterproof enclosures if installed outdoors .
• Keep fiber and copper connections separate to prevent accidental damage to the optical strands . By following these steps, you can safely connect the power portion of a composite optical cable while maintaining reliable data transmission over the fiber.
