It is applied to the surface of the fiber core in two layers to protect the optical fiber from mechanical punching.
The cost accounts for 6%-8% of optical fiber manufacturing .
Because coating products belong to the chemical category, coating products in the optical communication industry chain where the optical fiber is located have received a low degree of attention.

Because coating products belong to the chemical category, coating products in the optical communication industry chain where the optical fiber is located have received a low degree of attention.
The main raw materials of 6%-8% optical fiber coatings are polyurethane acrylate, epoxy acrylate, thinner, photoinitiator and some other additives.
Under normal circumstances, in order to save costs, companies will directly purchase polyurethane and acrylic, acrylate, ring Oxygen resin, etc.
, produce polyurethane acrylate and epoxy acrylate by ourselves.

In 2017, domestic environmental protection became stricter, and various raw materials were seriously affected by environmental protection.

In particular, in the second half of 2017, the production of photoinitiator TPO continued to be discontinued, and imported TPO was also affected.
The price of TPO rose sharply, and the prices of other photoinitiators also rose sharply.
Photoinitiators play a major role in the cost of optical fiber coatings The proportion has risen from about 5% before, and once reached more than 20% .
Up to now, this situation is still continuing.

In fact, optical fiber coatings have two main functions, the most important of which is to ensure that the optical fiber works normally.
Optical fiber is a very fragile product, and it needs coating to fully ensure high-speed and effective signal transmission.
Secondly, the optical fiber needs to use coatings to ensure that operators receive relevant revenue under certain network performance.

In 2016, the domestic output of optical fiber was 300 million core kilometers, an increase of 14% compared with 2015.
In 2017, the domestic output of optical fiber was about 350 million.
Core kilometers, an increase of 16% compared to 2016 .
At present, the domestic optical fiber supply has become saturated, and the optical fiber market is facing an oversupply situation.
According to statistics, due to the saturation of downstream demand in 2018, the growth rate of domestic optical fiber production dropped to 9% , and the output was 378.
23 million core kilometers.
It is estimated that by 2019, domestic optical fiber production will continue to maintain a growth rate of about 10% .
The market demand for domestic optical fiber Still maintain a cautious attitude.
300 million 14% 350 million 16% 9% 37823 million 10%
And China, as a major global fiber production and consumer country, has a huge market demand gap.
At present, there are only ten domestic optical fiber coating manufacturers in my country, and the foreign optical fiber coating technology is mainly in the hands of established optical fiber coating manufacturers, such as Dutch DSM Diesel.
