Optical modules are the core components of optical communication systems and play a crucial role in fiber optic communication. They mainly perform photoelectric conversion functions. Do you know how long the lifespan of an optical module is?
The service life of a normal optical module is 5 years. Based on the usage of the optical module over time, if problems occur after about 1 or 2 years, it can be roughly judged that the quality of the module itself is a problem or that it is a second-hand module.
The second-hand light module has problems such as light path pollution, low receiving sensitivity, external cavity damage, high or low working temperature, and short service life. Defective merchants are reintroducing it to the market, and everyone should pay attention to lightning protection!
