Where should fiber optic cables be stored?
Optical cables should be stored in a dry, ventilated and UV-protected place such as a room or container. Choose a storage location with low humidity, no falling objects, no risk of chemical spills (oil, grease, etc.), open flames, or overheating. Elements such as humidity and other contaminants should also be considered when choosing a storage location. The place where the optical cable is stored should be flat and smooth. When the storage space is limited, the space can be leveled, and then put wood or bricks on the front and rear of the optical cable reel, and remember not to touch the optical cable.
Note: Although fiber optic cables can be stored outdoors, the exterior of the fiber optic spools may suffer from weathering or other damage due to weather changes. Therefore, it is recommended to store all fiber optic cables indoors.
Precautions when using fiber optic cables
For safety reasons, there are many things to be aware of when storing or using fiber optic cables, as follows:
- When storing fiber optic cables, it is best to wear a disposable apron to reduce fiber particles on clothing and keep all food and beverages away from the work area. If there are too many fiber particles, it may cause internal damage to the fiber optic cable.
- Always wear special safety glasses, a suitable hard hat, seat belt and protective gloves. Do not touch your eyes when using the fiber optic cable.
- Do not look directly into the fiber optic cable unless there is no light source at the other end of the fiber optic cable.
- Only work in a well-ventilated area and do not smoke when using the fiber optic cable.
- After using the optical cable, please wash your hands carefully.
- Do not use isopropyl alcohol to clean fiber optic cables because it is flammable.
After storing the fiber optic cable, its inspection and maintenance are also very important. Check the fiber optic cable for any damage during storage. If possible, check the condition of the optical cable protective cover first. If there is no protective cover, a heat shrink cap should be used to ensure the cable is kept sealed.
In addition to the precautions for storage, there are many points that need to be paid attention to when installing or using the optical fiber, such as avoiding sharply bending the optical cable, avoiding pulling the optical cable forcibly, and protecting the optical cable from lightning, etc. For more information, please refer to the precautions for optical cable installation.
Frequently asked questions about storage cables
Q: Can the fiber optic cable be bent at a right angle?
Answer: You can’t bend it at a right angle, which is not good for the optical fiber and is easy to damage. Optical fibers are generally bendable. Optical fibers and glass are made of the same material, both of which are silica. The reason why optical fibers can be bent is because of their structure. Because optical fibers are very thin, they are very soft. If glass can be made into optical fibers, it is so thin. Components can also be bent. However, the optical fiber can only be bent at a large angle, otherwise it will be broken like glass. The effect of fiber bending on network speed is also very small (except for breaks). The toughness of the optical fiber is relatively high. As for the degree to which the optical fiber can be bent, it is basically impossible to break the optical fiber by manpower. Some optical fibers are different. The toughness and bending lines of optical fibers between 0.2mm and 0.8mm in diameter have reached international standards.
Q: Will the bending of the fiber affect the speed of the Internet?
Answer: Yes, but as mentioned above, as long as the degree of bending is not too large, it will not have much effect, otherwise, the opposite is true.
The propagation mode of optical fiber is mainly based on the principle of total reflection. The optical signal is injected at the vertical end of the optical fiber, and propagates forward along the axial center line when it coincides with the axial center line of the optical fiber.
Q: Does the optical cable need to be sealed and stored?
A: The label on the fiber optic cable reel must be sealed and stored, because the label contains important information, such as fiber optic cable usage instructions, attenuation value, bandwidth and cable length, etc. These parameters are important information about the fiber optic cable and need to be stored well.
