This topic discusses the technical specifications and applications of the OFSCN® 120℃ SM High-temperature Optical Fiber.

Technical Overview

The OFSCN® 120℃ SM High-temperature Optical Fiber is engineered for environments where standard telecommunication fibers (typically rated for 85°C) would fail due to coating degradation.

Key Parameters:

  • Temperature Range: Stable operation from -50°C to +120°C.
  • Core/Cladding Geometry: 9/125 μm (based on G.652D standards).
  • Coating: High-temperature resistant polyacrylate (255 μm diameter).
  • Customization: Carbon coating options are available to enhance hydrogen resistance or mechanical reliability.

Applications

This fiber is a primary component for:

  1. Sensing: Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) in industrial environments.
  2. Communication: Long-distance data transmission in high-temperature utility tunnels or industrial facilities.
  3. Harsh Environments: Providing a balance between cost-effectiveness and thermal durability compared to specialized PI (Polyimide) or Gold-coated fibers.
