What is an industrial grade optical module?
Knowledge Base + 2024.01.22

Many people may not know that the optical module is an indispensable part of all network connectivity deployments. The emergence of a product often corresponds to market demand, we usually come into contact with most of the optical modules can only meet the commercial data center network deployment, so how to meet the realization of large-scale industrial network deployment? In this case, industrial-grade optical modules were born. So, what is the industrial-grade optical module?

What is the industrial-grade optical module

The operating temperature of the optical module is one of its most important parameters, it can have an impact on the other parameters of the optical module. In the optical module applied to the environmental temperature changes, its operating current and other parameters will also change, thus affecting its normal transmission. Industrial-grade optical modules are products developed to address this issue. Ordinary optical modules are mostly commercial-grade optical modules, the normal operating temperature of 0 ~ 70 ℃; and industrial-grade optical module operating temperature of -40 ℃ ~ 85 ℃, can be 85 ℃ under the high temperature and sub-zero work in harsh environments. In addition to industrial-grade optical modules in the electrical components, enclosures, etc. must be designed with scene-hardened components to ensure the service life of the module.

Application of Industrial Optical Module

Industrial optical modules are mostly used in industrial and factory automation, outdoor applications, railroads and intelligent transportation systems, marine, oil, gas, mining and other fields of industrial fiber optic media converters or Ethernet switches and other industrial Ethernet networks. Industrial-grade optical modules can meet the industrial Ethernet in the harsh operating environment of the lasting stability.

How to realize the industrial-grade standard of optical modules

The main reference standard of industrial-grade optical module lies in its operating temperature, so how to realize this standard?

1, hardware standards: industrial-grade optical modules used in the chip and laser must be used to achieve industrial temperature level products.

2, physical cooling: industrial optical modules to meet the high temperature in the stable operation must have a self-cooling function, industrial-grade optical modules mainly use heat dissipation silicone to carry out physical cooling, so that the heat generated by the laser as quickly as possible out of the heat.

3, temperature compensation: when the industrial-grade optical module in sub-zero low-temperature operation, in order to make its performance unaffected, it must be temperature compensation to ensure its normal operation at low temperatures. Temperature compensation of this work is more complex, need to consume a lot of time for technicians to calculate and write. This is the main reason why the price of industrial-grade optical modules is higher than the price of ordinary optical modules.

Well, the above content is the leap electronic on industrial-grade optical module is what? This issue is related to the detailed introduction, I hope it can help you!
