Analysis of application scenarios of products with different transmission distances of the module

As a photoelectric conversion device, in the optical communication network, the optical module is the most common product. Among the characteristics of optical modules, the transmission capacity is the most important parameter that has attracted the most attention. In addition, the transmission distance of the optical module is another core parameter that cannot be ignored. In different fields and links of optical communication network transmission, the characteristic requirements of optical modules are also different.

Analysis of application scenarios of products with different transmission distances of the module

According to the different transmission distances of optical modules, they can be divided into three types: short-distance optical modules, medium-distance optical modules, and long-distance optical modules. Among them, long-distance optical modules specifically refer to optical modules with a transmission distance of more than 30km, which can meet The need for long-distance transmission of network data.

In the actual use of long-distance optical modules, in many cases, the maximum transmission distance of the module cannot be reached. This is because a certain degree of dispersion occurs during the transmission of optical signals in optical fibers. In order to solve this problem, long-distance optical modules use Only one dominant wavelength is my DFB laser as the light source, which avoids the problem of dispersion.

There are long-distance optical modules in SFP optical modules, SFP+ optical modules, XFP optical modules, 25G optical modules, 40G optical modules, and 100G optical modules. Among them, the long-distance SFP+ optical module uses EML laser components and photodetector components, which reduce the power consumption of the optical module while also improving the accuracy; the long-distance 40G optical module uses a driver and a modulation unit in the transmission link, which is The link uses optical amplifiers and photoelectric conversion units to achieve a maximum transmission distance of 80km.

However, the transmission distance of the optical module is not as far as possible, and appropriate solutions should be adopted in due course. The long-distance applications are mainly in server ports, switch ports, network card ports, security monitoring fields, telecommunication fields, Ethernet, synchronous optical fiber networks and other fields.
