Optical fiber access usher in the inflection point FTTH and FTTB or will coexist for a long time

July 22, 2021

On May 31st, at the China Optical Network Symposium, Zhang Chengliang, deputy chief engineer of the Beijing Research Institute of China Telecom Group, disclosed that the worldwide PON industry chain has rapidly matured recently, and optical fiber access has ushered in an inflection point to fully replace copper cable access. In the future, the domestic market will be dominated by FTTH and supplemented by FTTB, which will coexist for a long time and complement each other.

The data shows that the overall global FTTX has steadily grown in the near future, and China has become the main supporting force for the development of FTTx. According to OVUM's prediction, the promotion of broadband strategies in various countries and the explosive growth of Internet video services will promote the rapid and rapid growth of global FTTx. Among them, the influence of China is becoming more and more important. It is estimated that by 2016 China will account for 50 of the global FTTx user market. %the above.

With the rapid maturation of the PON industry chain worldwide, optical fiber access has ushered in an inflection point for the full replacement of copper cable access. According to the "12th Five-Year Plan" of broadband network infrastructure, fixed broadband access users will have a net increase of 130 million, and FTTH users will exceed 40 million, which will have a large new market in the future.

In recent years, China's telecommunications and radio and television network operators have invested in large-scale FTTB networks, which basically have high bandwidth capabilities and can be smoothly upgraded to provide higher bandwidth. Internationally, the concept of FTTH is also widely used, including FTTB. Zhang Chengliang stressed that in China, FTTB will still exist for quite some time and it will occupy an important position. The future domestic market FTTH and FTTB will coexist for a long time.

Zhang Chengliang stated that under the circumstance that the FTTB can meet the bandwidth requirements, the short-term transformation of the FTTB should be avoided to reduce unnecessary waste. In some of the more special new scenarios, FTTB is still the most economically reasonable construction mode at this stage.

The newly built area should mainly adopt the construction mode of full coverage of FTTH. The urban transformation area should be adapted to local conditions and be mainly covered by thin FTTH to avoid blindly implementing the overall translation.
