Driven by both technology and ecology, we delve into the core business scenarios of government and urban governance, empowering high-quality development

1. Optical transmission board

The optical transmission board is the basic board type of OSN3500, and its main function is to achieve optical transmission. According to different transmission media, optical transmission cards can be divided into SDH optical transmission cards and WDM optical transmission cards. SDH optical transmission cards can achieve STM-1/4/16/64 transmission, while WDM optical transmission cards can achieve DWDM and CWDM optical transmission.

2. Optical switch board

Optical switch board is an important type of board used in optical transmission networks, whose main function is to implement optical path switching and wavelength switching. According to different switching methods, optical switching cards can be divided into optoelectronic conversion switching cards, electro-optical conversion switching cards, and optoelectronic optical switching cards. Optoelectronic conversion exchange cards and electro-optical conversion exchange cards can achieve conversion between different wavelengths, while electro-optical exchange cards can achieve exchange between different optical paths.

3. Optical monitoring board

Optical monitoring board is an auxiliary board type used for optical transmission networks, whose main function is to achieve optical power detection and optical path monitoring. The optical monitoring board can achieve optical power detection of optical signals and status monitoring of optical paths, thereby achieving monitoring and maintenance of optical transmission quality.

4. Other board types

In addition to the three common types of cards mentioned above, OSN3500 also has other types of cards, such as protection cards, expansion cards, etc. The protection board can achieve protection switching of the system, thereby improving the reliability and stability of the system; Expansion cards can expand the functionality and capacity of the system to meet different network requirements.
