Selection skills of single-fiber bidirectional optical modules

All optical modules are composed of two functions of receiving and transmitting, so that photoelectric conversion and electro-optical conversion can be performed, so that the optical module is inseparable from the devices at both ends of the network. The selection skills and usage of single-fiber bidirectional optical modules believe that many people know that the components of optical modules include optoelectronic devices, functional circuits and optical interfaces, etc. The optoelectronic devices include two parts: transmitting and receiving. The optical module can convert electrical signals into optical signals through photoelectric conversion at the sending end, and then convert the optical signals into electrical signals at the receiving end after transmission through optical fibers.

Selection skills and use of single-fiber bidirectional optical modules

With the wide variety of optical modules, more and more customers have begun to pay attention to the stability and reliability of the modules themselves. At present, the popular optical modules on the market are mainly divided into three types: original optical modules, second-hand optical modules and compatible optical modules. As we all know, the price of original optical modules is very high, and many manufacturers can only stay away. As for second-hand optical modules, although the price is relatively low, the quality is not guaranteed, and packet loss often occurs after half a year of use. Therefore, many manufacturers have turned their attention to compatible optical modules.

Indeed, the performance of the compatible optical module in use is almost the same as the original optical module, and the price is several times cheaper than the original optical module, which is why the compatible optical module can be popular. However, the products on the market are mixed, and many merchants are shoddy and confused, and many consumers are miserable. In order to protect the interests of our customers and friends, Finit will tell you in detail the precautions for purchasing optical modules.

First of all, the first question, how do we distinguish between new optical modules and second-hand optical modules? We mentioned above that second-hand optical modules will lose packets after half a year of use, which is caused by unstable optical power and reduced optical sensitivity. If we have an optical power meter, we can take it out and test it to see if its optical power matches the parameters on the data sheet.

Then observe the after-sales usage of the optical module. The service life of ordinary optical modules is 5 years. It is basically difficult to see the quality of the optical module in the first year, but it can be seen in the second or third year of use.

I believe many people know the selection skills and usage methods of single-fiber bidirectional optical modules. We also need to see how temperature adaptable the optical module is. Generally speaking, the temperature range of the optical module used is 0°C~70°C. If it is in an extremely cold or extremely hot environment, you need to use an industrial-grade -40°C ~85°C optical module.
