How Long Is the Service Life of the Optical Module?

Optical modules on the market are mainly divided into original optical modules, compatible optical modules, and second-hand optical modules. Original optical modules are expensive and generally have a service life of 5 years. If there is a problem within 1 or 2 years, then you can The rough judgment is that there is a problem with the quality of the module itself or it is a second-hand module. In addition, the scrapped optical modules can also be recycled and can be used in aerospace, petrochemical, and other fields. How long is the service life of the specific optical modules and what can be done with the recycling of optical modules, let’s take a closer look at the article!

The Service Life of the Optical Module

The optical module is the core accessory of the optical communication system and plays a vital role in optical fiber communication. It mainly completes the photoelectric conversion function. So do you know how long the service life of the optical module is?

The service life of a normal optical module is 5 years. Depending on the use of the optical module over time, if there is a problem in about 1 or 2 years, it can be roughly judged that there is a problem with the quality of the module itself or a second-hand module.

Second-hand optical modules have problems such as optical path pollution, low receiving sensitivity, external cavity damage, high or low operating temperature, and short service life. Bad merchants put them on the market again, everyone should pay attention to lightning protection!

Precautions for Selecting Compatible Optical Modules

Compared with the original optical module, the price of the compatible optical module is much lower, so what are the precautions for choosing a compatible optical module?

1. Compatibility: Equipment manufacturers of optical modules will encrypt their equipment to varying degrees, which is what we call compatibility. Modules of your own brand can only be used on your own equipment, and optical modules of other brands cannot be matched with your own equipment. Compatibility manufacturers need to perform different compatibility adaptations on optical modules, and it is particularly important to be able to perfectly solve the adaptation problem.

2. Service life: The service life of a normal optical module is 5 years. Depending on the use of the optical module over time, if there is a problem in about 1 or 2 years, then it can be roughly judged that there is a problem with the quality of the module itself. Or used modules.

3. Optical module performance: The performance indicators that affect the optical module mainly include average transmitted optical power, extinction ratio, optical signal center wavelength, overloaded optical power, receiving sensitivity, and received optical power. The performance of the optical module can be judged. It can be viewed through DDM information. In addition, it can also be judged by whether the signal of the optical module is stable, whether there is a delay, and whether there is packet loss during the transmission process.

4. Whether it is a second-hand module: When purchasing a compatible optical module, you must be careful not to blindly pursue low prices. Second-hand modules often have various problems shortly after use.

The quality of the optical module can directly affect the transmission effect of the optical fiber link. So far, more and more suppliers have a limited selection of compatible optical modules. The quality is completely comparable to the original optical module, but the price is very competitive, which can help customers save a lot of costs. To build a safe and stable network environment, reduce costs and improve efficiency, compatible optical modules are preferred.
