Guangxi OPGW fiber optic cable manufacturer, price of overhead ground wire OPGW fiber optic cable in Mudanjiang City, Heilongjiang Province

Description :

　　Prevent and reduce micro bending and stress of OPGW

　　Sharp angles are not allowed (with a minimum bending radius of 500mm);

　　The diameter of the OPGW cable reel should not be less than 1500mm;

　　The diameter of the pulley should be more than 25 times the diameter of the OPGW, generally not less than 500mm; the inner side of the pulley should have nylon or rubber pads to prevent scratching the surface of the OPGW;

　　Attention should be paid to encapsulating the ends during the construction and installation of OPGW;

　　In addition, before the OPGW arrives at the site and is installed, the optical fiber splicing should be carried out after the installation is completed, and after the completion of the entire line construction, the optical fiber attenuation acceptance test of the OPGW should be conducted on site in a timely manner.

　　Operating wavelength of 1310nm or 1550nm

　　2 Attenuation: 1310nm 1550nm<; 0.37dB/km < 0.25dB/km
