Outdoor FTP CAT5E External PVC+PE Double Jacket with Messenger Data Cable
Outdoor Cat5e FTP with Messenger cables are designed for aerial installations where the cable must be suspended between poles or structures. The integrated steel messenger provides mechanical support, eliminating the need for separate support wires while maintaining EMI protection through foil shielding.

- Tensioning: Apply calculated tension (use dynamometer)
- Sag Setting: Adjust to design specifications
- Termination: Separate cable from messenger, ground messenger
- Testing: Continuity, shield integrity, performance verification
Special Considerations:
- Clearance Requirements: Minimum 5.5m over roadways, 3.5m over sidewalks
