The application of fiber optic splice closure has been quite extensive in radio and television networks, and the fiber optic splice closure is a weak link in the construction and maintenance of optical cable lines. In practice, some products have reasonable functional design, and various factors are considered more realistic, but there are also some. Product, functional design aspects are not considered or practical.
As a quality, some products are blindly pursuing cost reduction, resulting in structural simplification, long-term sealing, inability to cut corners, reduced strength, unsustainable life, or inferior recycled plastics, resulting in mechanical strength and corrosion resistance of fiber optic splice closures. Sexuality does not meet the requirements of the index, or the use of inexpensive sealing materials to make the sealing performance of the fiber optic splice closure drop too fast, this phenomenon is very unfavorable for long-term reliable operation of the cable line.
Because the production process of fiber optic splice closure is simple, the technical requirements are not high, and even the production can be imitated. In bad weather, such as typhoon and heavy snow, the problems are basically domestically produced some relatively poor quality fiber optic splice closures, and good quality cable joints. The box is still well sealed after immersion, and there is no water leakage problem, and it also shows good tensile resistance on overhead lines.
Therefore, according to the geographical environment, climatic conditions, and the actual needs of network construction and maintenance, the fiber optic splice closure equipment must select brands and products with reliable performance and quality, and strictly control the quality of materials. The material used for the fiber optic splice closure depends on the production date, the quality of the material is tested, and the simulation test is performed. Since the sealing tape and the rubber bead are not easily weathered for a long time, the degree of adhesion is lowered and should be checked before use. When batch feeding, it should be sampled and tested before being used.
