1. Under eaves
The standard LAN cable can be used only when it is not directly exposed to sunlight or ultra-high temperature. It is recommended to use pipes. Ultraviolet (UV) -- Do not apply the cable without UV protection to the direct sunlight environment.
2. On the exterior wall
Avoid direct sunlight on the wall and man-made damage. Heat -- The temperature of the cable in the metal pipe or trunking is very high, and many polymeric materials will reduce their service life at this temperature.
3. In pipes (plastic or metal)
For example, in pipes, pay attention to the damage of plastic pipes and the heat conduction of metal pipes. Mechanical damage (repair cost) -- The repair of optical cable is very expensive, and at least two terminations are required at each breakpoint.
4. Overhead applications/overhead cables
Consider cable sagging and pressure. Whether the cable is directly exposed to sunlight.
5. It is directly laid in the underground cable trench, and the control range of this environment is very small. The installation of cable trench shall be checked regularly for dryness or wetness. Grounding - If the shielding layer of the control cable needs to be grounded, the corresponding standards must be followed.
6. Underground pipeline
In order to facilitate future upgrading, cable replacement and isolation from surface pressure and surrounding environment, auxiliary pipeline is a better method. However, do not expect the pipeline to remain dry forever, which will affect the selection of cable types. Water -- The moisture in the LAN twisted pair cable will increase the capacitance of the cable, thereby reducing the impedance and causing near end crosstalk problems.
