[Free sample available] The optical fiber is protected by a metal tube, making it highly resistant to environmental conditions and easy to install.
The optical fiber for distributed optical fiber sensing is strongly protected by various seamless metal tubes, making it highly resistant to environmental conditions and easy to install. 【Features】 ◎ The optical fiber is encapsulated within the metal tube in a state of negative excess length. ◎ The optical fiber is intermittently fixed to the metal tube by crimping. → Appropriate tension is applied to the optical fiber in advance to ensure initial sensitivity as a sensor. → Prevents sensor damage caused by local large deformations due to phenomena such as crack formation. ◎ Sensor application environments: Stainless steel tube type: Normal atmospheric conditions. Incoloy tube type: Environments requiring resistance to chlorine, hydrogen sulfide, and electrocorrosion. *Environment: Stainless steel or Incoloy can be selected according to the application environment. *Additionally, it can also be used for temperature sensors and FTTH. ★☆★ Free samples available ★☆★ If you would like a free sample, please contact us with your intended application (planned use) using the contact information below.

Company information
Nippon Steel & Sumitomo Metal Corporation Welding Industry Division began developing metal tube optical fibers by applying welding material manufacturing technology in 1984, with the concept of "optical fibers that can be handled like electric wires," inserting optical fibers into thin, unseamless metal tubes. In 1988, they started selling the product under the name "PICOLOOP." Since then, they have responded to customer needs by releasing products such as "Picoflex," which can be flexibly bent, and the portable "Picodrum." Furthermore, recently, they have utilized the characteristics of optical fibers themselves as sensors, contributing to the construction, management, and maintenance of social infrastructure, as well as disaster prevention and security, fostering a safe, secure, and comfortable society.
