Can network patch cords be placed near a heat source?

Network pacth cords are usually not recommended to be placed near heat sources. This is mainly because the performance and maintenance of network pacth cords, especially fiber optic pacth cords, are affected by various factors, among which heat sources are an important adverse factor.
Firstly, the raw material of fiber optic pacth cords is glass, which is more fragile and sensitive to temperature changes compared to materials such as copper wire. If exposed to high temperatures for a long time, the performance of fiber optic pacth cords may be affected, such as a decrease in the strength of optical signals, and even micro cracks or permanent damage, thereby affecting the quality and speed of network connections.
Secondly, heat sources may also cause signal interference and loss, cause to slow network connection speeds, disconnections, and other issues. This is because the heat generated by the heat source and electromagnetic radiation may interfere with the optical signal transmission inside the fiber optic cable, thereby affecting the stability and reliability of the entire network.
In addition, placing network pacth cords near heat sources may increase the difficulty and cost of maintenance. Due to the irreversible damage caused by high temperature environments to network pacth cords, once a problem occurs, it may be necessary to replace the entire jumper, which not only increases maintenance costs but may also affect the normal operation of the network.
Therefore, to ensure the performance and stability of network pacth cords, it is recommended to place them away from heat sources and take appropriate measures for protection and isolation. For example, network pacth cords can be secured to walls or other safe locations using fixed devices to prevent them from coming into contact with high-temperature objects or other forms of damage. At the same time, regular inspection and maintenance of network pacth cords, timely detection and resolution of problems, is also an important measure to ensure stable network operation.
