Network rack temperature
Maintaining 68°F–77°F (20°C–25°C) minimizes overheating risks while balancing cooling expenses. ASHRAE recommends this range for modern servers, though some operators push to 80°F (27°C) for energy savings. Environmental standards are provided for rack level monitoring, ambient monitoring and water leak detection. Depending on size of the room: close to the door, center of room, center of racks and furthest point. Server rack temperature directly affects hardware reliability, energy efficiency, and operational costs. 2 °C increase in ambient temperature yields a -17. In other words, there's a clear correlation between data center temperature and rack equipment temperature. When, exactly, does this become a problem? It varies by the equipment, but most CPUs are at risk. Recommended environment: 20–24 °C and 45%–55% RH; in servers, inlet 18–27 °C according to ASHRAE.

Principle of High Temperature Measurement Optical Cable
Distributed temperature sensing (DTS) measures temperature distribution over the length of an optical fiber cable using the fiber itself as the sensing element. Temperature measurement can be achieved through various methods, including: However, these traditional systems often suffer from limited immunity to electromagnetic. Since the measuring chain is a functional combination of optical methods, optical fiber properties, and other photonic elements together with control electronic circuits, it is necessary to nd a suitable compromise between the chosen measurement method, fi measuring range, accuracy, and resolution.
