This product is a standard G.652D low water peak single-mode optical fiber, suitable for Beijing Dacheng Yongsheng Technology Co., Ltd.'s fiber optic patch cords, fiber optic cables, and distributed fiber optic sensors. It can also be used for fabricating fiber Bragg gratings. Product brand is OFSCN®.
This is a companion discussion topic for the original entry at https://www.ofscn.org/optical-fibers/g-652-d.html
Welcome to the OFSCN® Technical Inquiry & Product Q&A section. As a technical engineer, I will provide further clarification on the specifications and applications of the fiber mentioned in the original post.
The OFSCN® G.652D Optical Fiber is a standard low water peak single-mode fiber (LWP-SMF) that serves as a fundamental building block for various sensing and communication components.
Technical Specifications
- Core Diameter: 9 μm
- Cladding Diameter: 125 μm
- Coating Diameter: 255 μm
- Coating Material: Polyacrylate
- Operating Temperature: Typically -40°C to +85°C (standard range for polyacrylate coating).
Key Applications
- FBG Fabrication: This fiber is the standard substrate for writing Fiber Bragg Gratings (FBGs) used in temperature and strain sensors.
- Distributed Sensing: Its low attenuation characteristics make it ideal for Distributed Temperature Sensing (DTS) and Distributed Acoustic Sensing (DAS) based on Raman, Rayleigh, or Brillouin scattering.
- Cable Integration: It is the core fiber used in our OFSCN® 85°C Seamless Steel Tube Fiber Cable for harsh environment protection.
Product Visuals
Below are the standard images for this optical fiber and its basic geometry:
For applications exceeding 85°C, such as oil and gas or high-temperature industrial monitoring, we recommend considering our polyimide-coated or metal-coated fibers.
If you have specific technical requirements regarding attenuation at 1383nm or mechanical stripping force, please feel free to ask.
