1. The detection optical fiber is stored in the cable tray, and the protective package shall be retained before installation, and the cable tray shall be kept upright to prevent cable collapse and damage to the detection optical fiber. During storage and transportation, always pay attention to detecting the bending radius and tension limit of optical fiber.
2. During optical fiber wiring, Φ 0.9 optical fiber tension is less than 4kg; Φ 3. The tension of optical fiber is less than 10kg; The tensile force of armored optical fiber is less than 30kg
3. When paying off the optical fiber on site, use a slender rod to horizontally pass through the center of the optical fiber winding disc and rotate the winding disc for paying off. It is forbidden to put the optical fiber winding disc on the ground and rotate the optical fiber from the disc for paying off.
4. The end of the optical fiber away from the temperature measurement host shall be treated as follows: take the last 30 cm long Φ 0.9 optical fiber (if there is sheath or armor, remove it), wrap the optical fiber around a small circle with a diameter of 1cm for 10 turns.
5. The bending radius of the detection optical fiber must be greater than 30mm. The detection optical fiber shall not be seriously worn or crushed when passing through the wall and pipe.
6. When multiple optical fibers pass through the same long metal or PVC pipe, it is necessary to ensure that the optical fiber passes through at one time, and it is not allowed to pass through the optical fiber in several times.
7. The detection optical fiber shall not be dropped, bent and twisted vigorously, impacted by gravity, stretched by excessive force, etc., so as to avoid the fracture of the detection optical fiber core.
8. The type and specification of optical fiber used in the project shall meet the provisions and requirements of the design.
