A New Cost-effective Solution for 100G Network:100G CFP4 Optical Transceiver

At the process of gradual network upgrade from 10G-40G-100G, 40G/100G optical components are widely applied in various industries, especially in the optical interconnect industry. In the next few years, 100G products will continue to prevail. At the same time, optical communication module based on standardized dense wavelength division will attractive more and more attention and will be widely accepted by the market. Thereinto, the CFP optical module is the product under the development of 100G technology.

The 100G CFP optical module, also called as the 100G client module, is a module with hot-pluggable form factor. The CFP series optical modules have experienced the development of CFP, CFP2, CFP4 since the CFP was launched. However, it seems that CFP4 optical module is the most cost-effective solution among them, and is widely praised. Then in this post, the introduction to this solution will be made.

A Brief Introduction to 100G CFP4 Optical Transceiver
The 100G CFP4 module is developed based on CFP, CFP4. It has the same rate as that of CFP/CFP2 optical module, but the transmission efficiency has been greatly improved. Besides, the power consumption is reduced, and the cost is also lower than that of CFP2. Therefore, CFP4 optical module has an irreplaceable advantage. Next, the advantages of CFP4 optical module will be involved in.

Advantages of CFP4 Optical Transceiver Module
By comparison, CFP4 optical transceiver is with the following outstanding advantages demanded by most of network users:
1. With higher transmission efficiency: the early 100G CFP optical module achieves the 100G transmission rate through 10*10G channels, and the 100G CFP4 optical module now achieves 100G transmission through 4 25G channels, so the transmission efficiency is higher and the stability is stronger.
2. With smaller volume: the volume of the CFP4 optical module is 1/4 of the CFP, which is the smallest optical module in the CFP series light module.
3. With higher integration of modules: the integration of CFP2 is 2 times that of CFP, and the integration of CFP4 is four times that of CFP.
4. With lower power consumption & cost: the transmission efficiency of CFP4 optical module is obviously improved, and the power consumption is decreased and the cost of system is lower than that of CFP2.

These advantages of CFP4 optical modules have attracted wide attention. Simultaneously, due to these merits, CFP4 will be preferred in the fields, such as data centers requiring ultra high bandwidth and core routers.

Conclusion
Currently, the main types of CFP4 series optics include 100GBASE-SR4 CFP4,100GBASE-LR4 CFP4 in the market. It is believed that 100G will become the future network development with the expansion of 100G deployment in the scale. In addition, the costs in the 100G optical transceiver module and entire 100G network deployment will be reduced with the advancement of network tech. Generally speaking, Gigalight considers that 100G CFP4 bring the new solution for 100G Ethernet. To some degree, it will contribute to the development of 100G at faster pace.
