Hello, everyone!
Today, I want to continue to explain a new topic – ODN engineering and maintenance. Now, I will continue to explain ODN engineering. Today, the topic is construction safety.

Before the start of construction, it is necessary to obtain a building permit for the works. During the installation of optical cables, we must constantly pay attention to safety. Prior to the execution of works, the construction site must be secured. Different types of fences and bumpers are used, as well as appropriate traffic signs. The construction site must be clearly visible even in situations of poor visibility - fog, snow, rain, and night.
On the construction site, all persons must have personal protection - helmet, protective gloves, special footwear, and clothing, etc.
Complete tools and instruments must be tested, calibrated, and safe to operate. Staff must know all the tools, instruments, and equipment they work with. Occasional training is also organized.
All active equipment, metal cabinets, and boxes, and optical cables with metal elements must be properly grounded.
Special care should be taken when working in environments where there is a risk of ignition and explosion. For example, the entrance and splicing in manholes are wounded until the amount of flammable and explosive gases is determined. Before entering, the manhole is required to be open for some time, and measurements are made with a special instrument. If it is safe, entry is allowed, but splicing is not allowed. The tool is carefully lowered, etc.
Fiber optics should also be handled carefully to avoid injury as the optical fibers are visually impaired. They can easily stay on clothes, fly into food or water. Therefore, one should be careful. Smoking is not allowed during splicing.
PON requires high optical power, especially if CATV is enabled. These are optical powers from 18 to 22 dBm, which is an extremely high optical power. Care must be taken during the operation not to direct the fiber into the eyes, as this could lead to injury.
This is the end of this article. I will continue to explain this topic in the next article >> ODN Engineering and Maintenance (20).
Thank you!
