DVOA Intelligent Attenuator Board is developed by GIGALIGHT for addressing the issue of unstable optical power in optical communication lines. It serves the purpose of automatic optical gain adjustment and protecting the optical receiver. It is connected in the optical fiber communication link to ensure uninterrupted communication. The panel provides a setting button for convenient installation and debugging. The LED indicator on the panel displays the current system operating status, providing clear visibility. The system is designed to operate stably in harsh environments and is widely used in intelligent adjustment of optical lines, including PDH, SDH systems, Ethernet systems, wavelength division multiplexing (WDM) systems, and other optical systems.


Product Features
