Considerations for Cold Aisle Applications

• Material Selection: LSZH, PTFE, or PUR tubing ensures low smoke, flame resistance, and chemical stability.
• Flexibility and Bend Radius: Tubing must accommodate tight bends in data center cold aisles without inducing microbends that increase signal loss.
• Environmental Resistance: Tubes should withstand temperature fluctuations, humidity, and potential mechanical stress.
• Compatibility: Ensure tubing is compatible with fiber types and connectors to maintain low insertion loss. These manufacturers provide a range of solutions tailored for low-loss, high-protection fiber management in cold aisle and other demanding environments, making them suitable for data centers, industrial, and specialized optical applications.
