DVOA - Dynamic Variable Optical Attenuator
HYD Technology has developed a DVOA card, also known as an intelligent attenuation card which is used to resolve the issue of unstable optical power in the optical lines of communication.
This card automatically adjusts and protects the optical receivers, and it can be connected in series to avoid interruptions in communication with the fiber link.
It contains a panel with buttons that can be used to ensure proper installation, and the panel has an LED indicator that also shows the system’s status. This module can work well in harsh design and is used in intelligent adjustment systems in optical lines like SDH, Ethernet, WDM, and PDH.
- Offers easy maintenance and is hot-swappable.
- Manual and intelligent adjustment methods are supported.
- Offers a design that has excellent heat dissipation and is adaptable to all kinds of environments and temperatures.
- Offers a redundant backup power supply and adapts to a wide range of voltage.
- Supports SNMP networks and methods like CLI and NetRiver.
