1.4G all come, 3G 2G still have a place to use it? In the same way, 10G 40G is definitely useful. Different options with different options!

　　2. There is still demand for 155 and 622 modules, but it is only a matter of quantity.

　　3.40G should be a transitional product. This year's volume has come down. The demand for 100G optical modules has become clear this year, and it should grow rapidly next year. The 100G upgrade will drive the demand for 10G SFP+. The previous 2.5G modules may have to be replaced. 10G SFP+ replaced.

　　4. No. It has been shouted for decades that light enters copper and retreats, and copper cables are still used in the field of communication.

　　5. Of course not, the research and development speed of 100G optical modules in the optical fiber industry is very fast, but it does not mean that the rest are useless. The optical fiber industry has generally entered the Gigabit era, and applications such as 10G optical fiber modules and optical fiber network cards are more common. Optical fiber industry giants and domestic brands are developing 40G and 100G. 40G does not have a real large-scale application, needless to say, 100G is used a lot. Therefore, the elimination process is very slow.

　　6. No, the cost of 100G optical modules is still very high

　　7.100G is different from 40G. It has many advantages of its own. It should develop rapidly. In 2013 alone, the three major operators are collecting large-scale data. It is believed that 100G will perform well in 2014.

　　8. Optical modules of 1-10G and higher speed will show great power in local area network and metropolitan area network. 100G can only be used for trunk lines at present, and there are many problems.
