Customer background
The customer is a certain institute under the Chinese Academy of Sciences, and there is a scientific research project in 2024, part of which involves optical communication WDM transmission.
Business challenge
1. The number of DWDM wavelength-division channels required for optical communication WDM transmission involved in the subject is 32CH, requiring that the insertion loss of any channel is less than 3dB, and the isolation degree of adjacent channels is at least 40dB;
2. The isolation degree of adjacent channels of conventional DWDM wave division equipment on the market is low, only about 25~30dB;
3. The insertion loss of DWDM with a wavelength fraction of more than 16CH on the market cannot meet the requirements of any channel less than 3dB;
Solution and value embodiment
1. After repeated communication and testing with the customer, Xiantong Technology finally delivered the WDM equipment that fully meets the customer's needs;
2. The isolation of adjacent channels is greater than 50dB, and the isolation of adjacent flight channels is greater than 80dB;
3. The WDM equipment has a total of 32 channels, and after strict testing, the insertion loss of any channel is less than 3dB;
4. After customer testing, the products delivered by Xianyitong Technology not only meet customer requirements, but also exceed customer requirements, and the most popular customer scientific research project experiment has been successfully completed.
