Recently, the latest white paper on the Fiber Development Index in 2021 released by the market research company shows that the top five countries in the world in the fiber development index in 2021 are Singapore, South Korea, the United Arab Emirates, China and Qatar, and the United States ranks first. Ranked 18th, the survey tracked and measured the development of fiber optics in 81 countries/regions. This article, ETU-LINK, will take you to see it together.

As one of the important methods of modern information transmission, optical fiber communication has the advantages of large capacity, long relay distance, good confidentiality, no electromagnetic interference and copper saving. With the adoption of FTTH and FTTC systems in my country, the integration of triple play and the continuous construction of large-scale 3G, the market demand for optical fiber and cable continues to increase, providing a strong impetus for the development of my country's optical fiber and cable industry. According to statistics, in 2021, China's optical fiber and cable industry will achieve a total industrial output value of 68.802 billion yuan, sales revenue of 64.310 billion yuan, a year-on-year increase of 24.68%, and a profit of 6.554 billion yuan, a year-on-year increase of 47.39%. The proportion of optical fiber and cable broadband users has increased from 56% at the end of 2015 to 94%, the gigabit optical network covers more than 120 million households, the scale of 4G base stations accounts for more than 50% of the global total, 792,000 5G base stations have been opened, and 5G mobile phones have been opened. The number of terminal connections reached 260 million.

The white paper pointed out that the top five countries all benefited from strong national bandwidth plans, and developed countries such as the United States, Australia and the United Kingdom lag behind in the optical fiber development index, mainly due to the lack of clear or aggressive national plans and the lack of incentives for operators.

The development trend of optical fiber communication technology mainly has the following three points:

1. Ultra-large capacity, ultra-long-distance transmission technology Wavelength division multiplexing technology can greatly improve the transmission capacity of optical fiber transmission systems, and has broad application prospects in future cross-sea optical transmission systems.

2. Optical soliton communication is to use optical soliton as a carrier to realize long-distance and distortion-free communication, and the information transmission can reach thousands of miles under the condition of zero bit error.

3. All-optical network is the highest stage and ideal stage of the development of optical fiber communication technology. The traditional optical network realizes all-opticalization between nodes, but electrical devices are still used at the network nodes, which limits the further improvement of the total capacity of the current communication network trunk.

Finally, the "White Paper" states that by 2026, the proportion of the world's population connected to the Internet will increase from the current 58% to 70%, of which 30% will access the Internet through mobile devices and 40% through the home. Fixed broadband connection.
