Guangdong optical fiber welding | Guangdong optical fiber welding machine | Guangdong optical fiber welding quotation | Guangdong optical fiber welding optical fiber technology has a long history. Optical fiber welding is to connect two optical fibers together through equipment, which requires professional optical fiber welding equipment
Optical fiber transmission has the advantages of transmission frequency bandwidth, large communication capacity, low loss, immunity from electromagnetic interference, small diameter of optical cable, light weight, rich sources of raw materials, etc., so it is becoming a new transmission medium. The transmission of light in optical fiber will produce loss, which is mainly caused by the transmission loss of optical fiber itself and optical fiber Connector Composition of fusion loss at. Once the optical cable is ordered, the transmission loss of the optical fiber itself is basically determined, and the fusion loss at the optical fiber joint is related to the optical fiber itself and the on-site construction. Efforts to reduce the fusion loss at the optical fiber joint can increase the transmission distance of optical fiber relay amplification and improve the attenuation margin of optical fiber link.
Our company has a professional construction team for optical fiber fusion installation, which undertakes optical fiber fusion engineering and integrated wiring engineering, optical fiber access, campus network construction, Security Monitoring system, enterprise wiring. Professional optical fiber welding technicians are available door Fused fiber.
1、 Main factors affecting fiber fusion loss
There are many factors that affect the splicing loss of optical fiber, which can be roughly divided into intrinsic factors and extrinsic factors of optical fiber.
1. The intrinsic factors of optical fiber refer to the factors of optical fiber itself, mainly including four points.
(1) The fiber mode field diameter is inconsistent;
(2) The core diameters of two optical fibers are mismatched;
(3) The core section is not round;
(4) The concentricity of core and cladding is poor.
Among them, the fiber mode field diameter inconsistency has a great impact. According to the recommendations of CCITT (All Telegraph and Telephone Advisory Committee), the tolerance standards for single-mode fiber are as follows:
Mode field diameter: (9~10 μ m) ± 10%, that is, the tolerance is about ± 1 μ m;
Cladding diameter: 125 ± 3 μ m;
Concentricity error of mode field ≤ 6%, cladding out of roundness ≤ 2%.
2. The non intrinsic factor that affects the fiber splicing loss is the splicing technology.
(1) Axial misalignment: the single mode fiber core is very thin, and the axial misalignment of two butt joint fibers will affect the splicing loss. When the dislocation is 1.2 μ m, the connection loss reaches 0.5dB.
(2) Axis inclination: when the optical fiber section is inclined by 1 °, it will produce about 0.6dB of splicing loss. If the splicing loss is required to be ≤ 0.1dB, the inclination of single-mode optical fiber should be ≤ 0.3 °.
(3) End face separation: the connection of movable connector is not good, which is easy to cause end face separation, resulting in large connection loss. When the discharge voltage of the welding machine is low, it is also easy to produce end separation, which can be generally found in the welding machine with tensile test function.
(4) End face quality: When the flatness of the end face of the optical fiber is poor, it will also produce losses, even bubbles.
(5) Physical deformation of optical fiber near the connection point: tensile deformation of optical fiber cable during erection, too large pressure of clamped optical fiber cable in the connection box, etc. will have an impact on the connection loss, and even the welding can not be improved for several times.
3． other Influence of factors.
Operation level, operation steps, winding process level, cleanliness of welding machine, welding parameter setting, cleanliness of working environment
