The safety and efficient operation of energy infrastructure depend on stable and reliable data transmission. In critical energy fields like oil, natural gas, and electric power, equipment is constantly exposed to environments of high heat, humidity, and even corrosive agents. Traditional PVC or standard acrylate-coated fiber optic patch cords quickly age and crack in these conditions, leading to data transmission interruptions that severely compromise monitoring system reliability and production efficiency.

This topic highlights a critical challenge in energy infrastructure. Standard fiber optic components often fail in harsh environments, such as oil/gas wells and power systems, due to the degradation of traditional coating materials.
To ensure stable data transmission in environments reaching up to 120°C, the selection of both the fiber coating and the protective jacketing is essential.
Technical Solution: OFSCN® 120°C Series
Based on the requirements for high-reliability data transmission in high-temperature energy sectors, the following components are engineered to prevent data loss:
-
OFSCN® 120℃ Fiber Optic Patch Cord
This patch cord utilizes a 0.9mm seamless stainless steel tube for mechanical protection, ensuring the internal fiber is shielded from physical stress and corrosive agents.
- Temperature Range: -40℃ to +120℃.
- Components: Integrated with 120℃ high-temperature fiber and specialized connectors.
-
OFSCN® 120℃ SM High-temperature Optical Fiber
The core of these systems is the fiber itself. Unlike standard PVC or acrylate fibers, this fiber uses a high-temperature resistant polyacrylate coating.
- Fiber Type: G.652D Single Mode (Multi-mode also available).
- Coating: Specialized polyacrylate designed to withstand continuous 120°C exposure without cracking or increasing attenuation.
-
OFSCN® 120℃ Fiber Optic Connector
Standard connectors use epoxies and plastics that soften at high temperatures. These specialized connectors (FC, ST, SMA905) are rated for 120°C to maintain precise alignment and low insertion loss.
Visual Reference:
For applications exceeding 120°C, such as deep-well monitoring, the technology shifts toward Polyimide-coated fibers (up to 300°C) or Gold-coated fibers (up to 700°C) combined with specialized metal-buffered cables.
