VOA500

GT LASERS VOA500 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.

VOA500 is a standard type product. Each attenuator with an attenuation value of monitoring. 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.

◉ DWDM system, power adjustment and automatic equalization in multi-channel.

◉ Power control into narrowband wavelength division multiplexers (WDMs) and configurable networks.

◉ In Lab.
