What is a "High-Temperature Resistant" patch cord?

If placed in boiling water at 100°C, can this patch cord still transmit signals effectively?

Yes, an OFSCN® high-temperature resistant fiber optic patch cord can transmit signals effectively when placed in boiling water at 100°C.

In fact, 100°C is well within the standard operating range for these specialized components. To provide a professional technical analysis, the reliability of a patch cord at such temperatures depends on two key factors:

1. Material Resistance

Standard communication patch cords typically use PVC or LSZH jackets, which begin to soften or release toxic fumes near 80°C. In contrast, OFSCN® high-temperature patch cords utilize specialized materials such as:

  • PI (Polyimide) Coating: Stable up to 250°C–300°C.
  • PTFE/PFA/FEP (Fluoropolymers): Resistant to heat and moisture, maintaining structural integrity in boiling water.
  • Metal Coating (Gold/Copper/Aluminum): Used for even more extreme environments.

2. Resistance to Hydroxyl (OH-) Penetration

Boiling water introduces a high-humidity environment. Standard fibers may experience increased attenuation over time due to hydroxyl ion penetration. OFSCN® high-temperature fibers are designed with specific cladding and coatings to minimize this “water peak” effect, ensuring signal stability even in submerged conditions.
