In 2019, operators began to deploy Gigabit broadband on a large scale and build a Gigabit broadband city. By the end of November 2019, there were 720000 fixed Internet broadband access users with access rate over 1000m nationwide. The total number of FTTH / O users in China is 418 million, accounting for 92.5% of the total fixed broadband users; the access rate of 100Mbps and above accounts for 84%.
The challenges faced by 5g network are first of all the challenges of business model. Operators need to consider where the profitable business is, 2C market is saturated, and the revenue is difficult to grow; 2B market has great potential, but needs to be cultivated, and the competition situation is complex. Secondly, the construction investment is facing challenges. How to reduce the cost of equipment, and where is the source of investment when the operators' own business growth is weak. Finally, the challenges of network technology, SBA and cloud network, NR and high-frequency communication (energy consumption, coverage), network slicing and MEC, etc.
What are the new opportunities of 5g for optical communication? 5g carrier network will increase capacity and bring some new demands. The theoretical peak value of 5g base station is about 25 times of 4G, and the theoretical average value is about 15 times of 4G; the prediction of 5g user Dou is about 6 times of 4G at present. With regard to 5g's forward and back transmission scheme, each operator has different considerations, and the key is the technical development and cost. The cost of optical modules and devices in the communication network is more and more large, which restricts the overall cost of the network. Operators hope that optical module / device manufacturers can reduce product costs and promote the rapid deployment of the network through innovative ways.
As for the collection of optical modules, operators hope to promote more open industrial chain. Operators hope to promote the opening and decoupling of the network. On the one hand, to promote the decoupling of equipment, in the future, equipment can be combined through different modules, not only limited to a certain equipment manufacturer. At present, the decoupling of fiber access is very mature, and home gateway can be purchased in the market. At the same time, the direct collection of optical modules of operators is facing technical challenges, and the compatibility of different modules of different devices. Secondly, maintenance and after-sales, responsibility division. Finally, the management and guarantee of optical module suppliers.
