Common causes of optical module damage

As one of the essential accessories for optical network communication, optical modules are widely used in application scenarios such as data centers, base stations, local area networks, and backbone networks. As an accessory product, the optical module will naturally be damaged during use, and this damage includes natural damage and man-made damage.

The factors of natural damage are very simple. Generally, the optical module has reached its service life, naturally aging, and the components do not work or the operating efficiency is very poor; we mainly talk about the damage of the optical module caused by man-made.

1. The optical module interface is polluted

The optical module is often used as the last link of the network construction. Sometimes it will be idle after purchasing, plug in the network equipment, unplug the dust plug, and it will not run. In the long run, dust will inevitably cause the interface of the optical module to be polluted; the use will be polluted The jumper will also pollute the interface of the optical module. Therefore, the dustproof plug should not be removed before using the optical module, and a new uncontaminated jumper should be connected when using it;

2. Electrostatic damage

Electrostatic damage is a relatively common phenomenon, and the electrostatic discharge process will cause serious damage to the optical module. At the same time, when the electrostatically adsorbed dust accumulates to a certain extent, it will change the impedance between the lines, which will not only affect the normal use of the optical module, but also shorten the life of the optical module. When using the optical module, you should pay attention to the electrostatic protection work, and you need to wear an electrostatic wristband or anti-static finger cot;

3. Optical power overload

Optical modules are divided into short-distance, medium-distance and long-distance transmission. The long-distance working environment often uses the corresponding distance module. If the long-distance transmission optical module is used to transmit short distance, the received optical power of the optical module will be reduced. If the value is too high, the optical module will be burnt out. In order to prevent the module from being burned out, an optical attenuator should be added to reduce the received optical power.

Whether it is an optical module or other network equipment, it can generally adapt to its working environment. As long as the corresponding operating specifications are followed during operation, it will not cause damage.
