Research on Test Method and Test System of WDM Device for 5G Fronthaul Network
Abstract
Wavelength Division Multiplexing (WDM) devices, as one of the core components of 5G fronthaul network, have developed rapidly in recent years. The fronthaul network has proposed new requirements for WDM devices, components and products. However, the technical requirements and test method standards of WDM devices for 5G fronthaul network are not clear. Through in-depth analysis of the problems encountered in the test of WDM devices, we propose a test method of 5G fronthaul WDM devices, and build the corresponding test system, which is compared with the manual test method. The results show that the proposed test method has 10 times more efficient than manual test method with good consistency.
