1. Under the eaves. Standard LAN cables can only be used when not directly exposed to sunlight or ultra-high temperatures, and it is recommended to use pipelines. Ultraviolet (UV) - Do not use cables without UV protection in direct sunlight environments.
On the exterior wall. Avoid direct sunlight on the wall and human damage. Heat - The temperature of cables in metal pipes or cable trays is very high, and many polymer materials will reduce their service life at this temperature.
3. Inside the pipeline (made of plastic or metal). If in a pipeline, pay attention to the damage of plastic pipes and the thermal conductivity of metal pipes. Mechanical damage (repair cost) - Fiber optic cable repair is very expensive, requiring at least two terminations at each breakpoint.
4. Suspended applications/overhead cables. Consider cable sag and pressure. Is the cable directly exposed to sunlight.
5. Directly laying in underground cable trenches has a limited control range. The installation of cable trenches should be checked regularly for dryness or moisture levels. Grounding - If the shielding layer of the control cable needs to be grounded, the corresponding standards must be followed.
6. Underground pipelines. For future upgrades, cable replacement, and isolation from surface pressure and surrounding environment, installing auxiliary pipelines for isolation is a better method. But don't expect the pipeline to remain dry forever, as this will affect the choice of cable type. Water - Moisture in twisted pair cables in a local area network can increase the cable's capacitance, thereby reducing impedance and causing near end crosstalk issues.
