Breaking the Limit: How the OFSCN® 120℃ High-Temperature Fiber Optic Patch Cord Achieves “Zero” Fault Communication in High-Heat Industrial Environments

Introduction: The Invisible "Heat" Challenge

In critical sectors such as modern industrial automation, oil and petrochemical, aerospace, and nuclear power, equipment demands unprecedented stability and reliability from data communication. However, many core components operate in high-temperature environments, often exceeding 80℃ or even 100℃. Traditional standard fiber optic patch cords see their transmission performance degrade rapidly and their coatings age prematurely at temperatures near 85℃, leading to communication outages and significant economic losses.

Beijing Dacheng Yongsheng Technology Co., Ltd. (DCYS) recognizes this critical bottleneck. Engineered specifically to solve extreme environment communication challenges, we proudly introduce the OFSCN® 120℃ High-Temperature Fiber Optic Patch Cord. This product is designed to help your systems achieve true "zero" fault communication, even in the harshest thermal conditions.

I. Core Breakthrough: A Dual Guarantee of Thermal Reliability

Our 120℃ high-temperature patch cord is not merely a jacket upgrade; it represents a fundamental innovation in its two core components: the optical fiber and the connector.

1. Specialty Fiber: Core Resilience to Thermal Stress

Traditional optical fiber uses a standard acrylate coating, which can decompose and embrittle under high heat, leading to increased micro-bending loss. The OFSCN® 120℃ patch cord utilizes a Modified Acrylate Coated Fiber:

• Temperature Rating Up to 120℃: This far exceeds the limits of standard industrial-grade fibers, ensuring structural integrity during continuous high-temperature exposure.
• Ultra-Low Attenuation: The optimized coating material ensures that when the fiber expands and contracts due to heat, micro-bending loss is strictly controlled, minimizing signal attenuation. We provide comparative insertion loss (IL) data at 20℃, 85℃, and 120℃ to empirically prove its performance stability under heat.

2. High-Temperature Connectors: Long-Term Connection Reliability

The weakest point of a patch cord often lies at the connector interface. OFSCN® utilizes specially engineered 120℃ high-temperature connectors:

• Heat-Resistant Ceramic Ferrule: We select ceramic materials with an extremely low thermal expansion coefficient, ensuring that the ferrule’s end-face geometry remains stable even with dramatic temperature swings.
• High-Temperature Epoxy and Curing Process: Standard epoxy is replaced with a dedicated high-temperature adhesive to ensure the fiber-to-ferrule bond remains secure at 120℃. This eliminates fiber pistoning and end-face degradation.

II. Indestructible: All-Metal Armor for Harsh Physical Environments

High-temperature environments are often accompanied by severe vibration, high pressure, and corrosive gases. The OFSCN® 120℃ patch cord offers maximum physical protection.
