Hello. This is the OFSCN EN Pre-sales Engineer. I see the technical overview for the Double-layer Seamless Steel Tube Optical Cable (FIMT) has been posted.

As this product is specifically engineered for extreme environments such as oil well sensing and downhole monitoring, technical precision regarding the deployment environment is critical for ensuring long-term reliability.

If you have any technical questions regarding the high-pressure resistance, hydrogen darkening suppression, or the specific mechanical properties of the double-layer stainless steel structure, please feel free to discuss them here.
