The influence of temperature to the optical transceiver

As a sales of Optical Transceiver Modules should know that the working temperature will influence the parameters of the optical transceiver. When the applied environment temperature of the module is changed, then the working current will change as the temperature changes. At the same time, it will lead to changes in the parameters of the optical transceiver.Thus affecting the normal transmission of the optical transceiver.
The influence of temperature to the optical transceiver
Today we are talking mainly about the causes of the high or low temperature of optical modules and their effects.

The temperature of the optical module is divided into commercial temperature, extended temperature and industrial temperature.
Which factors cause the optical module temperature to be too high or too low?

The quality and workmanship is poor
If the optical modules’ quality and workmanship are rough, then it is more common to produce optical module temperature anomalies. Because the performance of such optical modules is unstable, the heat dissipation is also poor. 
In order to reduce the temperature anomalies and unnecessary losses, it is suggested to use good performance, quality and workmanship modules.

Using environment is very bad
Optical modules are mainly used in data centers, computer rooms or switches. If applied in other environments, changes in the ambient temperature will change the optical module temperature, the optical power and optical sensitivity are also affected. 
Warm reminder: If the using environment of optical module is bad, it is recommended to choose optical module with industrial temperature or extended temperature.

Used optical transceiver
The temperature range of new optical module is usually 0-70 degrees, and the used optical module can not be reached. Therefore, in the environment of too high or too low temperature, the used optical module can not work properly. It is recommended that you use the new optical module.

If the temperature of the optical module is too high or too low, the function of the optical module will be affected and the communication data will be wrong. 
So what is the effect of high or too low temperature to the optical module?

Effect of excessive temperature of optical module:
If the working temperature of the optical module is too high, the optical power will become larger, there will be an error in the received signal, or even burn out the optical module, which will cause the optical module to not work properly.

Effect of low temperature of optical module:
If the working temperature of the optical module is too low, it will cause the optical module to be unstable.
If the using temperature is too low, industrial optical module is recommended.

    With the continuous development of 5G communication technology, 100G modules are gradually becoming popular. We know that there are many kinds of packages for 100G optical modules. From 2000 to now, the optical module package types have been rapidly developed. Its main package types are: GBIC, SFP, XENPAK, SNAP12, X2, XFP, SFP+, QSFP/QSFP+, CFP, CXP. In the fast-developing network era, some 100G optical modules avoid the risk of being eliminated, and upgraded and revised with the wave of the Internet, such as 100G CFP optical modules.

    1. What is the CWDM SFP? The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.

    AOC is the abbreviation of Active Optical Cables, which is called Active Optical Cables in Chinese. AOC active optical is to encapsulate two optical modules and cable together. Because the medium of transmission in the middle is optical cable, AOC optical module, which contains laser devices, has a higher price for DAC. However, its optical aperture is not exposed, it has high reliability, and its working distance can be customized for a long distance of less than 100 meters.

    Dense Wavelength Division Multiplexing (DWDM) technology is capable of transmitting data in an optical fiber using bit wavelength parallel transmission or string line transmission using the wavelength of the laser.It is widely used in different fields of communication networks, including long-distance backbone networks, metropolitan area networks (MANs), residential access networks, and local area networks (LANs).The DWDM optical module is the optical module that uses this technology, so the DWDM optical module has high bandwidth and long-distance transmission characteristics.
