Peak Performance, Pushing the Limits: Why OFSCN® 700-C-SST is the Industry Gold Standard for High-Temperature Optical Cables

In the world of industrial sensing and specialized communications, there are "no-go zones" where heat is intense enough to melt most plastics and corrosive gases are strong enough to devour conventional metals. The OFSCN® 700-C-SST seamless stainless steel tube high-temperature optical fiber cable, launched by Beijing Dacheng Yongsheng Technology Co., Ltd., was born specifically to establish connections within these forbidden zones.

It is widely recognized as the industry benchmark because it demonstrates overwhelming technical strength across four critical dimensions.

1. An Unrivaled Temperature Range: From -200°C to 700°C

While most specialized cables begin to struggle at 300°C, the 700-C-SST pushes the design boundary directly to 700°C.

• Beyond Just Heat Resistance: It can equally withstand extreme cold down to -200°C. This means it performs effortlessly in both cryogenic monitoring (like liquid nitrogen environments) and the fiery heart of an industrial boiler.
• Physical Stability: Utilizing specialized Silicon Dioxide (SiO2) fibers and proprietary coating processes, it ensures no sudden optical loss or physical embrittlement during extreme thermal cycling.

2. "Submarine-Grade" Protection: Laser-Welded Seamless SST

Many manufacturers use wrapped or braided stainless steel jackets, but the 700-C-SST utilizes true Longitudinal Laser-Welded Seamless Steel Tube technology.

• Hermetically Sealed Structure: This 316L stainless steel "skin" is 100% airtight. It completely prevents the infiltration of hydrogen, water vapor, and corrosive fluids, eliminating the "hydrogen darkening" issue that has long plagued the fiber optic industry.
• High-Strength Armor: Though it looks like a thin wire, it possesses immense tensile and crush resistance, making it rugged enough for the most complex downhole installation environments.

3. Dual-Purpose Design: The Unity of Sensing and Communication

The 700-C-SST is more than just a signal-carrying cable; it is an array of tens of thousands of sensors.

• Distributed Sensing: When paired with DTS/DSS (Distributed Temperature/Strain Sensing) systems, it provides real-time monitoring of temperature gradients and strain variations along the entire length of the cable.
• High-Bandwidth Transmission: While ensuring physical toughness, it retains the high-bandwidth characteristics of optical fiber, guaranteeing real-time and stable data transmission even in harsh conditions.

4. Extreme Thinness and Flexibility

Despite being encased in hardened stainless steel, the 700-C-SST maintains an astonishingly small diameter (common specifications range from 0.6mm to 1.2mm).

• Lightweight and Agile: Its minimum bend radius is remarkably small, allowing for flexible routing similar to standard electrical wires.
• Micro-Invasive: The ultra-fine diameter means it requires almost no structural changes to existing equipment during installation, making it the ideal choice for the digital transformation of legacy systems.

Conclusion: Choosing OFSCN® is Choosing Ultimate Reliability

In the global field of specialized optical fibers, Beijing Dacheng Yongsheng Technology Co., Ltd. consistently uses advanced material science to challenge physical limits. The OFSCN® 700-C-SST is not just a product; it is our highest commitment to industrial safety and precision monitoring.

When your multi-million dollar equipment requires "eyes" in an extreme 700°C environment, the 700-C-SST is the ultimate tool to help you see it all.
