Can this type of cable be used on outdoor utility poles? Will the jacket crack after prolonged exposure to sunlight?
Standard indoor patch cords are generally not recommended for outdoor utility pole applications. Here are the technical reasons and a more suitable alternative based on your environment:
1. Material Limitations (PVC Jacket)
The OFSCN® Standard Fiber Patch Cord typically uses a PVC jacket. PVC is not UV-stabilized; prolonged exposure to direct sunlight will cause the plasticizers to migrate, making the jacket brittle. Over time, this leads to cracking, moisture ingress, and eventually fiber failure due to environmental stress.
2. Mechanical Strength
Indoor patch cords rely on Kevlar for tensile strength, but they lack the rigid reinforcement needed to withstand wind loads or ice accumulation on utility poles.
Recommended Solution: PE Jacketed Armored Patch Cords
For outdoor overhead environments, you should use a product with a PE (Polyethylene) jacket, which offers excellent UV resistance and weatherability.
I recommend the OFSCN® 3.0mm Steel Wire Rope Fiber Optic Patch Cord.

Why this is suitable for your application:
- UV Resistance: It features a PE jacket specifically designed to withstand outdoor sunlight without cracking.
- High Tensile Strength: It incorporates a 0.45mm stainless steel wire strand structure, providing a tensile strength of >1200N. This allows it to handle the mechanical tension required for pole-to-pole or pole-to-building spans.
- Crush Resistance: The internal 0.9mm seamless stainless steel tube protects the fiber from physical damage and environmental pressure.
