With the continuous advancement of network technology, KSD cable products have been used in large-scale applications such as telecommunications network construction, national information highway construction, and FTTH fiber to the desktop. At this time, our quality requirements for fiber optic cables are getting higher and higher, so what are the problems related to the quality of ADSS fiber optic cables?
Today, we mainly analyze the quality of ADSS optical cable from the following four aspects:
1. Check the manufacturer’s qualifications and corporate background. It mainly depends on whether it is a big manufacturer, a big brand, whether it is committed to the development and production of optical cable products, whether there are many successful cases, whether it has ISO9001 quality system certification, whether it meets the ROHS directive, etc.
2. Check the product packaging. The standard length of optical cable supply is generally 1km, 2km, 3km, 4km and customized length specifications. Positive and negative deviations are allowed, and the deviation range can refer to the factory standard of the manufacturer. Check the outer sheath of the optical cable to see if it has obvious marks such as the number of meters, the name of the manufacturer, and the type of the optical cable. Generally speaking, the factory optical cable is wound on a solid wooden reel and protected with a wooden sealing plate. The two ends of the optical cable are sealed. The following marks are on the optical cable reel: product name, specification, reel number, length, net/gross weight, date, A/ B-end signs, etc.; check the optical cable test record, there are normally two copies, one with the cable reel on the inside of the wooden reel, the optical cable can be seen by opening the wooden reel, and the other is fixed on the outside of the wooden reel.
3. Check the sheath of the optical cable. The outer sheath of the indoor optical cable is generally made of polyethylene, or flame-retardant polyethylene, or low-smoke and halogen-free materials. The high-quality appearance is smooth and shiny, and the hand feels good. It has good flexibility and is easy to peel off. The outer skin of poor quality optical fiber cable is not smooth. When peeling off, the outer skin is easy to adhere to the tight sleeve and aramid inside. Note that some products use sponge instead of aramid material. The PE sheath of the outdoor optical cable should be made of high-quality black polyethylene. After the cable is formed, the outer skin is smooth, bright, uniform in thickness, and free of small bubbles.
4. Check the steel wire for reinforcement. Many structural outdoor optical cables generally contain steel wires for reinforcement. According to the technical requirements and production requirements, the steel wire in the outdoor optical cable needs to be phosphated, and the surface is gray. After the cable is formed, there is no increase in hydrogen loss, no rust, and high strength. However, some optical cables are replaced by iron wires or even aluminum wires, and the metal appearance is white, and the bending resistance is poor.
