The utilization rate of plastic optical fiber has increased, but market competition is still insufficient

With the rapid development of the optical communication industry, optical fiber, as the transmission medium of optical signals, plays the role of
information superhighway.
In recent years, with the rapid development of short-distance, large-capacity data communication systems and lighting industries, the utilization rate of plastic optical fibers has become higher
and higher.
Although plastic optical fibers have excellent tensile strength, high durability and small footprint, they look
at it as a whole.
Plastic fibers are not competitive enough
.

Some industry analysts pointed out that the rising use of plastic optical fiber does not mean that it has occupied an absolute advantage
.
Although plastic optical fiber has the advantages that quartz optical fiber does not have in short-distance communication and optical fiber sensing, in terms of temperature stability, plastic optical fiber has high temperature resistance, performance is not competitive, and its price does not have a strong competitive advantage
.

From the perspective of loss, the loss of plastic optical fiber is large, the loss of quartz fiber is only 0.
18db/km, while the loss of plastic optical fiber is 0.
5db/km, and the loss per kilometer of plastic optical fiber is too large
.
The optical fiber has not yet entered the family, or in the pilot, there are relatively few domestic plastic optical fiber manufacturers, and there is still a large gap
in transmission bandwidth with foreign countries.
In terms of price, the price of foreign quartz optical fiber has dropped to about 40 yuan, while domestic plastic optical fiber is still 600 to 700 yuan, which is not comparable
.

However, it is undeniable that it has an important position
in the data transmission of home intelligence, office automation, industrial control networking, vehicle-mounted airborne communication network and military communication network in the future.
China should vigorously develop the plastic fiber industry, should establish a technical standard alliance, reduce standardization risks and costs, and coordinate technical standard language intellectual property contradictions
.
Cooperation between enterprises and the Soviet State Engineering Laboratory for Optical Fiber should also be strengthened
.
Through the National Engineering Laboratory, the enterprises of the plastic optical fiber communication industry chain are united to jointly solve technical difficulties
.
In addition, joint efforts should be made to address international trade barriers
.
Domestic optical fiber enterprises should unite and cooperate and actively protect their legitimate rights and interests
under the organization of industry associations.
Only in this way can the full potential
of plastic fibers be fully realized.

Although the utilization rate of plastic fiber has increased in recent years, due to the constraints of loss and price, compared with traditional quartz optical fiber, it has not formed its own distinct competitive advantage, how to reduce loss, improve bandwidth and heat resistance make the key
to improving its competitive advantage.
