Huatai DWDA-1000 series is integrated by DWDM, VOA and EDFA module in a 1RU or 3D rack. Each channel of DWDM with a high-resolution factor electronic control adjustable optical attenuator will adjust and equilibrium the power. The insertion loss, power loss because of the channel equilibrium of DWDM will be amplified and compensation by the build-in gain flatness EDFA. Compact and simple device structure, thereby reducing the connections between devices to improve the index and reliability of the system. Can be used in DWDM system power equilibrium, optical add and drop multiplexed (OADW) flexible and expediently.
Each of the DWDA-1000 has a optical output power monitor, inspect precision≤±0.1dB. It can be set auto power control mode. According to different network application DWDA-1000 has MU, DE, DM and AD four types optical electric mode and configure relevant EDFA (PA, LA, BA and MSA) available. RS232 and RJ45 provide communicate and network management interface, LCD in front panel provide the working parameter and fault alarm of the whole unit. All of the optical ports can be installed in front panel; also can choose the back panel.
