With the rapid growth of Internet IP data service, the demand for transmission line bandwidth is increasing. Now the application of 10G optical module is more and more widely, at the same time, 10G optical module manufacturers also began to increase, now to the user how to choose better cost-effective products raised a lot of doubts.

　　When selecting a 10G optical module, you should pay attention to the following points to select the best product with good quality and suitable quality.

　　1. Choose professional manufacturers and well-known module brands.

　　Professional fiber module manufacturers have professional production lines, detection equipment and dust-free environment in the production of optical modules. The optical modules produced have better reliability in quality. Compared with the production environment of small workshops, the laser of optical modules has better stability and reliability in terms of optical attenuation and sensitivity.

　　In addition, well-known brands are more guaranteed in after-sales service. WT brand is a well-known SFP module brand in China, which is used in major networks, databases and operation centers, and has a strong market influence.

　　2. Select the core materials for the optical module

　　SFP+ 10G optical module adopts imported brand new laser and chip, so that 10G optical module has better and more consistent optical power, sensitivity, extinction ratio, and the module can run stably in the subsequent work and adapt to better temperature environment.
