Ultraviolet (UV) - Do not apply UV-free cables to direct sunlight.
Heat - The temperature of a cable in a metal pipe or raceway is high and many polymeric materials will reduce their service life at this temperature.
Water - The moisture in a twisted pair cable in a LAN increases the capacitance of the cable, reducing the impedance and causing near-end crosstalk problems.
Mechanical Damage (Repair Costs) - Fiber optic cable repair is expensive and requires at least two termination at each breakpoint.
Grounding - If the cable's shield needs to be grounded, the corresponding standards must be observed.
The total length of the route (not only refers to the room) - The building uses outdoor LAN twisted pair cable, the total length to be limited to 90 meters. For 100Mps or 1000Mbps network, the laying distance can not exceed this limit. Such as the laying of the distance between 100 meters to 300 meters, you should choose cable.
