Huatai VOA700 series assemble multi high-resolution electricity controlled optical attenuators into 1RU or 3D housing, mainly applied to optical adjustment and automatic equilibrium in DWDM system's and multi-channel network and optical amplify network.
VOA700 series is a high-end product series. Each attenuator has high-resolution input and output optical power monitoring and attenuator value monitoring, with automatic mode and manual mode. Client can set the automatic fixed attenuation mode and automatic fixed output mode in automatic mode. RS232 and RJ45 provide serial communication and SNMP network interface. LCD on the front panel provides every work parameter and fault alarm of the whole unit. All the optical port can install on the front panel or back panel.
