The footsteps of 5G are getting closer and closer, and 5G information transmission not only relies on optical fiber as a medium, but also faces the demand
for a significant increase in transmission pipeline capacity.
Naturally, long-distance optical fiber transmission has become the focus
of the industry.
Recently, NEC Japan successfully demonstrated the long-distance transmission of a single optical fiber, with a transmission distance of more than 11,000 kilometers and a capacity of 50.
9Tbps, creating a new world record
.
This is the first time that a 50Tb transmission
of more than 10,000 km has been achieved using a C-L-band erbium-doped fiber amplifier (EDFA).
Behind the new record, it highlights the fierce competition
of big tech companies in long-distance fiber optic transmission.
Hengtong, Changfei, Zhongtian, Fiberhome and other enterprises are also vigorously developing low-loss, large-effective area optical fibers to meet the requirements
of long-distance trunk transmission.
With the continuous development of science and technology, the network has higher and higher requirements for data transmission capacity and transmission speed, and long-distance optical fiber due to its advantages of high capacity, high speed, long distance, etc.
, its importance is gradually highlighted, and is widely used in military, financial and other fields, especially for the submarine network connecting the world, long-distance optical fiber will have a huge impact
on the submarine transmission network.
