The demand for 4G construction optical modules has grown the most. 4G network construction generally uses the "optical fiber extension" (BBU + RRU) method, and the demand for optical modules is much higher than in the 2G / 3G era (2G basically does not use optical modules, and 3G networks have not been on the scale). At the same time, the demand for optical modules is extremely insensitive to changes in 4G station building methods (co-site / new building).
The demand for optical modules is very persistent. After the 4G network is deployed to a certain scale, as data traffic continues to increase, 4G network expansion will become the focus of future construction. It is manifested by the large increase in RRU and the expansion of the transmission network, which will further stimulate the demand for optical modules.
According to the situation of mainstream companies in the grassroots research industry, monthly shipments in August this year are expected to be 2-3 times the average monthly shipments last year, which can support the judgment of the industry.
Guangxun Technology (WTD) is the country's largest optical module manufacturer, with a market share (base station-type optical modules) estimated at about 40%, which will fully benefit from the future growth in network construction demand.
The bidding of China Mobile's main equipment has been implemented. With the substantial development of 4G construction, the monthly shipments of optical modules have further increased; the bidding of China Telecom and China Unicom's 4G trial network has been implemented.
