What is the difference between indoor optical cable and outdoor optical cable?
1. Usage environment
Indoor optical cables are mainly used for data communication, networking and local area network transmission inside buildings, and generally use PVC or LSZH as the outer covering material. Since the indoor environment is relatively stable and is not affected by natural environments such as wind and sun, the waterproof and weather resistance requirements of the outer skin material are not high.
Outdoor optical cables are mainly used to connect buildings between buildings or multiple buildings in a connecting area. They need to withstand special requirements such as wind and rain, moisture resistance, and oxidation resistance in the natural environment. Therefore, PE is usually used as the outer sheath material.
2. Outer jacket/outer sheath
The outer jacket/outer sheath of indoor optical cables is generally PVC or LSZH, which has good flame retardancy, anti-aging, is not easy to age, and is relatively soft.
The outer jacket/outer sheath of the outdoor optical cable is made of PE material, which has strong impact resistance, fire resistance, waterproof, anti-corrosion and cold resistance.
3. Protection level
The protection levels of indoor optical cables and outdoor optical cables are also very different. Indoor optical cables do not require special protection. The generally used outer sheath materials can be soft and easy to fold, which facilitates construction and wiring.
The use scenarios of outdoor optical cables are relatively complex, so the protection level is relatively high. Generally, it is necessary to ensure that the optical cables can not be damaged in humid environments and can work normally under high or low temperature conditions.
As mentioned in the full text, the difference between indoor optical cables and outdoor optical cables mainly lies in the use environment, outer jacket/outer sheath and protection level. Choosing the right optical cable is crucial for data transmission. It is recommended that you fully consider its usage scenarios and usage needs when selecting and using optical cables.
