Overcoming the pain point of 2.0 duplex optical cable outer diameter to make production smoother
For 2.0 duplex optical cables, the quality of the outer diameter is a key factor in determining product quality. Its dimensional accuracy and shape regularity not only directly impact subsequent installation but also crucially influence the stability of signal transmission. Deviations in this process can lead to construction delays, or even lead to quality risks such as excessive transmission attenuation. Therefore, avoiding these common outer diameter issues during production is of great practical value in improving production efficiency and ensuring communication reliability .
Common Problems and Solutions
1. Outer diameter deviation
Problem: The dimensions exceed the standard tolerance range,resulting in reduced installation adaptability and affecting system compatibility.
Main reasons:Imbalance in the ratio of pulling and extrusion speed, insufficient calibration accuracy of the diameter gauge and fluctuation in the melt fluidity of the sheath material.
Solution :
2. Poor roundness
Problem : The cross-section is not a perfect circle, resulting in uneven insulation protection and increasing the risk of mechanical damage.
Main reasons: insufficient mold precision or excessive wear, the bare optical fiber itself is out of roundness, the tight sleeve material is unevenly plasticized or contains impurities, and the tight sleeve material has abnormal lubrication.
Solution :
3. Adhesion problems
Problem : The core wire sheath and the outer coating are adhered to each other, which can easily cause micro-bending damage to the optical fiber during subsequent processing.
Main reasons: low melting point of the sheath material, insufficient cooling rate, mismatch of material hardness, and unreasonable process parameter settings.
Solution:
4. Rough or defective surface
Problem : Particles, cracks, bubbles and other defects appear on the surface of the sheath, reducing environmental resistance and service life.
Main reasons: insufficient plasticization degree of raw materials, unreasonable cooling process, and deviation in cross-linking parameter settings.
Solution :
Addressing the outer diameter issues of 2.0 duplex optical cables requires comprehensive quality control throughout the entire process. By precisely adjusting equipment parameters, rigorously selecting raw materials, and regularly maintaining molds, stable outer diameter quality can be achieved. Implementing these measures in production effectively improves the mechanical performance and transmission stability of optical cables, laying a solid foundation for reliable communication network operation.
