For connection to DTS temperature measurement equipment; equipped with connectors that can be plugged directly into the equipment without the need for pigtail splicing
For temperature sensing environments such as tunnels, subways, bridges and dams, and for fire alarm systems
Features
High tensile and crush strength
Good environmental adaptability, tolerant of high and low temperature differences
Meets the national standard flame retardancy requirements for optical fiber cables
Soft, flexible and easy to splice, making it especially suitable for on-site cabling installation
The cable structure can be modified to meet customer requirements, further enhancing its special adaptability
