Everyone knows that the optical module is a key factor affecting the performance of the entire network. Especially in the industrial Ethernet, the network connection control is mostly large-scale industrial equipment. The stability of the optical module is particularly important. Then, how do we choose industrial-grade optical What about the module? Next, the editor of amini technology will give you a detailed introduction on how to buy industrial-grade optical modules, let’s take a look!
1. Look at the temperature adaptability of the optical module
Temperature adaptability is the most important criterion for industrial optical modules. Compared with industrial optical modules, whether the surrounding environment is higher or lower than its operating temperature range, it will affect its optical power, optical sensitivity and other important parameters. Therefore, It is particularly important to see the temperature adaptability of the optical module. The maximum working temperature that industrial optical modules can adapt is ﹢85℃, and the minimum working temperature is ﹣40℃.
2. Look at the transmit optical power and receiving sensitivity of the optical module
The emitted light power of an industrial-grade optical module is the light intensity at the transmitting end of the optical module, and the receiving sensitivity is the light intensity that the optical module can detect. Both of these are in dBm, which is an important parameter that affects the transmission distance of the optical module. Therefore, it is necessary to understand the two parameters in detail when purchasing industrial-grade optical modules.
3. Look at the compatibility of the optical module
In addition to the performance of the above parameters, compatibility is also an important consideration when purchasing industrial-grade optical modules. It is mainly judged from its compatibility with equipment and other modules. When purchasing an optical module, you can communicate with the merchant to request a real machine test of the optical module to examine its compatibility with the equipment; see whether the production standard of the optical module is the corresponding international standard and whether it has FCC certification, and meets the requirements The optical modules under these conditions are compatible with each other.
Industrial-grade optical module solution
The amini technology industrial-grade optical module has extremely low waiting time in the entire temperature range of -40°C to 80°C. It is an ideal choice for building a green data center and reducing construction costs. Using high-sensitivity photodetectors, the sensitivity is as low as -11.1dBm, and the longest transmission can reach 40km, which can provide economical and efficient long-distance data center interconnection for industrial Ethernet connections in harsh environments.
