Selection of Optical Transceiver
2022/06/07 03:06:08

With the arrival of the 5G era and the wide application of optical transceiver, more and more customers are paying attention to the stability and reliability of optical transceiver. There are three types of popular optical transceiver in the market, which are original optical transceiver, second-hand optical transceiver and compatible optical transceiver.

As we all know, the price of original optical transceiver is very high, many manufacturers can only be prohibitive. On the other hand, second-hand optical transceiver, although their price is relatively low, their quality is not guaranteed. Data packets are often lost soon after they are used. Therefore, many manufacturers have turned their attention to compatible optical transceiver. In use, the performance of the compatible optical transceiver is almost the same as that of the original optical transceiver, and the price is several times cheaper than that of the original optical transceiver, which is the reason why the compatible optical transceiver is popular.

However, the optical transceiver in the market are uneven in quality, and many manufacturer is shoddy and pass away the sham as the genuine, which causes a certain difficulty in the selection of optical transceiver, how do we distinguish the new optical transceiver and second-hand optical transceiver? Let us analyze how to choose an optical transceiver from EXSENSE Electronics:

First, observe the data of the light transceiver

Data packets of second-hand optical transceiver are often lost after they are used. This is due to unstable optical power and reduced optical sensitivity. In this case, we can use an optical power meter to measure the data of optical transceiver and check whether the optical power is consistent with the parameter in the data manual. If the data difference is too large, it is a second-hand optical transceiver.

Second, observe the after-sale use of optical transceiver

The service life of a new optical transceiver is usually five years. It is difficult to determine whether an optical transceiver is good or bad in the first year, but we can determine whether an optical transceiver is second-hand in the second or third year.

Third, observe the compatibility between the optical transceiver and the device

Before purchasing an optical transceiver, we need to communicate with the supplier about the brand of the optical transceiver to better check whether the optical transceiver is compatible with the device.

Fourth, observe the temperature adaptability of the optical transceiver

The temperature of an optical transceiver is not high, but it usually works in an equipment room or a switch. If the temperature is too high or too low, the optical power and sensitivity of the optical transceiver are affected. Generally, the operating temperature range of an optical transceiver is from 0℃to 70℃. In extremely hot or cold environments, an industrial-grade optical transceiver needs to be used. Its operating temperature range is from -40℃ to 85℃.

In the process of optical transceiver use, if the function failure of optical module is found, it is generally the transmitting end failure and receiving end failure. The common reasons for failure mainly include the following aspects:

First, the optical interface of the optical transceiver is exposed to a dusty environment and is contaminated by dust;

Second, the end face of the optical fiber connector is contaminated, causing secondary pollution to the optical interface of the optical transceiver;

Third, improper use of end face of optical joint with tail fiber, such as end face scratching;

Fourth, use a poor fiber optic connector.

Therefore, we need to clean and protect the optical transceiver in daily use after purchasing the optical module correctly. After the optical transceiver is finished working, plug the dust plug in time. Otherwise, the optical contact is contaminated, which may affect the quality of the optical signal and lead to connection problems and error code problems.
